“Which finger does the engagement ring go on?” This is the question we type into our phones a few hours before the proposal, or just after saying “yes,” when we realize we’ve never talked about it with anyone.
The short answer fits in one line: in France, the engagement ring is worn on the ring finger of the left hand, which is the fourth finger counting from the thumb. But this rule is neither universal, nor mandatory, nor the same everywhere in the world.
This article answers everything: the finger, the hand, the origin of the tradition, what changes after the wedding, the order with the wedding band, the countries that do the opposite, and the special cases one is afraid to ask about.
Which finger is the engagement ring worn on in France?
In France, the engagement ring is worn on the left ring finger. This is the dominant custom, the one followed by almost all couples, and the one that those around you will immediately recognize.
The ring finger is the finger located between the middle finger and the little finger. On the left hand, looking at it with the palm facing down, it is the second from the outside.
This same finger will later host the wedding ring. The two rings therefore coexist on the same finger, which explains the next question everyone asks themselves: in what order?
Why the left hand?
For the majority of people, the left hand is the least used hand. A precious ring is subject to fewer bumps, less friction, and fewer products there.
That is a practical explanation, but the historical explanation is prettier, and we will get to that in a moment.
Is it an obligation?
Absolutely not. No law, no French religious rule mandates a specific finger. It is a social custom, nothing more.
Many left-handed women wear their engagement ring on their right hand for pure comfort, and no one finds fault with that.
Where does the left ring finger tradition come from?
The tradition dates back to ancient Egypt, then to ancient Rome, and is based on an anatomical belief that is as false as it is charming.
The vein of love
The Romans believed that a vein ran directly from the left ring finger to the heart. They called it the vena amoris, the vein of love.
Placing a ring on this finger therefore meant placing a direct bond on the heart of the loved one. Modern anatomy has disproven the existence of this unique vein, but the symbol has survived twenty centuries.
The Roman iron ring
In Rome, the annulus pronubus was an iron ring offered during the betrothal. It was not a decorative piece of jewelry but a contractual commitment: the iron symbolized strength and permanence.
This is the true ancestor of our engagement rings.
The diamond, a recent invention
The first documented diamond engagement ring dates back to 1477: Archduke Maximilian of Austria gave it to Mary of Burgundy.
But the generalization of the diamond to the general public only dates back to the mid-20th century, driven by an advertising campaign that has since become famous. In other words: the tradition of the finger is ancient; that of the stone is recent.
Left or right ring finger depending on the country
The French reflex is not the global reflex. In a good part of Europe, it is the right hand that carries the commitment.

The German case, the most confusing
In Germany, the couple wears the engagement ring on the left during the betrothal, then moves it to the right on the day of the wedding, where it becomes the wedding band.
One single ring, two successive statuses. It is an economical and elegant approach that many French couples are now adopting by choice.
The Brazilian case
In Brazil, both fiancés wear a ring on the right hand during the engagement. On the day of the wedding, each person moves their ring to the left hand.
The public gesture of switching hands is, in itself, part of the ceremony.
Which finger after the wedding?
This is where things get complicated, and where the question of order becomes concrete.
The traditional rule: the wedding band first
Tradition dictates that the wedding band be worn first, closest to the heart, therefore at the base of the finger. The engagement ring follows, on top.
Concretely, on the day of the wedding, the bride moves her engagement ring to her right hand before the ceremony. The wedding band is placed on the bare left ring finger, and then the engagement ring is placed on top.
The modern version: do as you please
More and more women are reversing the order for purely aesthetic reasons: an engagement ring with a high-set stone, placed at the base of the finger, is more visible and rubs less.
Others wear the wedding band on the left and the engagement ring on the right, to prevent the two rings from wearing each other down.
The question of wear
Two rings that are constantly touching will scratch each other, especially if one is 18K gold (softer) and the other is 14K gold.
If you want to wear them together on the same finger, choose metals of comparable hardness. We detail this point in our guide wedding band and engagement ring.
And for men, which finger?
The question still surprises, but it is becoming more frequent: many couples choose for both partners to wear a ring during the engagement.
In this case, the custom is the same: left ring finger in France. Men's models are generally wider, more understated, often without a visible stone or with a flush setting.
Each finger carries, in traditional symbolism, its own meaning. It is not an exact science, but it is useful to know before moving a ring at random.

The little finger is traditionally the finger for the family signet ring, the one bearing the crest or monogram. In hip-hop culture, the “pinky ring” has taken on a whole different dimension: a visible, bold piece, often the most impressive one on the hand.
Can you wear your engagement ring on another finger?
Yes, and it is sometimes even the best solution. A size that has become too small, manual work, pregnancy: all are legitimate reasons to temporarily move the ring.
Many women then wear it as a necklace, on a fine chain, until the situation changes. It is an elegant solution that keeps the jewelry close to you without risk.
Special cases one is afraid to ask about
Here are the concrete situations that come up most often in our exchanges with customers.
I am left-handed, should I change hands?
Nothing requires you to, but it is often more comfortable. The dominant hand suffers all the shocks: keyboard, steering wheel, bag, sports. Switching to the right protects the stone and the prongs.
My job prohibits jewelry
Caregivers, cooks, mechanics, laboratory personnel: many jobs prohibit rings for hygiene or safety reasons.
The most common solution is wearing it as a pendant during shift. A second option is wearing a silicone ring at work and the real ring outside of work.
My fingers swell, the ring no longer fits
This is extremely common, especially in summer, during pregnancy, or after a salty meal. Never force a stuck ring off.
Lift your hand for a few minutes, run it under cold water, then slide the ring off with a little soap while turning it. If it doesn't move, consult a doctor: a ring that constricts a finger long-term is a medical issue, not a jewelry issue.
We aren't getting married, but we want a ring
Nothing ties the ring to a ceremony. Many couples give an engagement ring without marriage plans, simply as a mark of attachment.
In this case, the finger has no constraints: choose the one you like and that fits you.
How do you know if the ring will fit the right finger?
All the symbolism in the world is useless if the ring doesn't fit. The ring size of the left ring finger is almost never identical to that of the right ring finger.
The rule of the dominant hand
For most right-handed people, the right ring finger is about a half-size larger than the left, because the dominant hand is more muscular.
If you plan to wear the ring on the right, never measure the left finger. It is the classic mistake that requires a trip to the workshop.
Measuring at the right time
Measure at the end of the day, at room temperature, never after sports or right after waking up. The difference between a morning finger and an evening finger can reach a full size.
Our jewelry size guide details the three measurement methods and the complete FR / US conversion table.
It seems impossible, yet it happens. In the stress of the moment, sliding the ring onto the middle finger happens more often than you'd imagine. The middle finger is the longest finger; the ring finger is the one right next to it, towards the little finger.
Measuring the wrong finger
Borrowing a ring she wears on her index finger to deduce the size of the ring finger gives an inaccurate result of one to two sizes. An index finger is almost always thicker than a ring finger.
Trying too hard to respect tradition
The best finger is the one where the ring is comfortable and visible. A rule that is two thousand years old is not worth three decades of daily discomfort.
History of the engagement ring: from Egypt to today
The question of the finger is only really understood by tracing the history. The engagement ring was not born with modern jewelry: it spans nearly five thousand years of history.
Throughout this journey, the ring has changed material, recipient, meaning, and sometimes hands. Here are the major stages, in order.
Ancient Egypt and the endless circle
The first documented engagement rings come from the Nile Valley. They were braided from reeds, hemp, or leather—poor materials that often needed replacing.
Their shape mattered infinitely more than their value. The circle, with no beginning or end, represented eternity; the void in the center represented a doorway, the passage toward a life together.
It is also in Egypt that the idea of a privileged finger, connected to the heart by an invisible canal, appears. This intuition would travel to Rome, where it would take on its Latin name.
Rome: from domestic iron to public gold
The Romans transformed a poetic image into an institution. The engagement ring became a legal object, presented before witnesses, which sealed an agreement between two families.
Two rings sometimes coexisted: an iron ring worn at home, robust and discreet, and a gold ring brought out for public occasions. The distinction indicated social status as much as attachment.
It is from this period that the first written descriptions of wearing it on the ring finger date, with the justification of the vena amoris that we saw above.
The Middle Ages and the gimmel ring
In the Middle Ages, the Church took control of the betrothal and the ring became a sign of religious as well as civil promise. Goldsmiths then invented pieces of astonishing ingenuity.
The gimmel ring, for example, consisted of two or three interlocking rings that could be separated. Each fiancé would wear a part of it during the engagement, and the rings were joined on the day of the wedding to form one.
This mechanism says exactly what an engagement ring is: half a story, waiting for its next chapter.
The Victorian era: sentiment set in stones
The 19th century invented sentimental jewelry. Colored stones were set, dates were engraved, locks of hair were hidden under an enameled lid.
Acrostic rings are all the rage: the initials of the gemstones form a word. A ruby, an emerald, a garnet, and an amethyst lined up could spell out a first name or a tender message.
At that time, an engagement ring was not necessarily a diamond. Sapphires, rubies, and pearls held at least as much importance.
The 20th century and the birth of the solitaire
The solitaire as we know it—a single, elevated stone held by four or six prongs—became standard in the middle of the 20th century. Prong settings release light beneath the stone and multiply its brilliance.
The shape has remained, but the materials have diversified. Today, a lab-grown diamond engagement ring or one in moissanite offers the same design with a different approach to the stone.
What hasn't changed since Egypt is the gesture: a circle, a finger, a promise.
The engagement ring across religions and cultures
The finger varies less by religion than by country, but every tradition has its own interpretation of the ring. Here is what is most commonly observed.
None of these practices have the status of an absolute rule: they coexist, blend, and evolve from one family to another.
Catholic tradition
In Catholicism, the engagement ring has no liturgical status. It is a social custom, whereas the wedding band is blessed during the ceremony.
In France and in the Latin countries of Western Europe, the left ring finger has become the standard for both. In Spain, however, the right ring finger remains the majority choice within the same Catholic parishes.
Orthodox tradition
Orthodox Christianity gives the engagement a much more formal role: there is an office of betrothal, distinct from the office of crowning.
The rings are blessed and then exchanged, and are traditionally worn on the right hand. The gesture of blessing is performed from right to left, which partly explains the choice of this hand.
Jewish tradition
In a Jewish wedding, the ring plays a central role: it is the object of value given to the bride, and tradition dictates that it be smooth and without stones, so that its value is immediately clear.
It is classically placed on the right index finger during the ceremony, then often moved to the ring finger afterward. The engagement ring, when it exists, remains a separate and optional practice.
Muslim tradition
Islam does not prescribe an engagement ring. The khitba, the period of betrothal, is often accompanied by a gift of jewelry, but the style and the finger remain a matter of local custom.
Depending on the region, the ring is worn on the right, the left, or not at all. Among men, solid yellow gold is sometimes avoided in favor of silver, steel, or a white metal—a subject we address in our article on white gold or silver.
Secular marriages and civil unions
Without a religious framework, freedom is total. Many couples invent their own ritual: a single ring for both stages, two rings worn on different hands, or a piece of jewelry that is not a ring at all.
Some couples choose a personalized piece of jewelry rather than a classic model. This is the logic behind our bespoke diamond pieces, conceived around a specific story.

Why some countries wear the ring on the right
This is one of the most frequent questions as soon as one has family abroad. Why does a Spanish, Polish, or Greek woman wear her ring on the right when France does the opposite?
The answer is not merely anecdotal: it blends Latin, religion, and political history.
The right hand, hand of the oath
In the ancient and medieval world, the right hand was the hand of honor. Oaths were sworn with the right hand, agreements were sealed with the right hand, and blessings were given with the right hand.
The left hand, conversely, carried an unfavorable reputation; the Latin word sinister has even given us an adjective in French (and English) that is far from flattering. Placing the ring on the right was, therefore, placing it on the noble side.
The fracture of the Reformation
In the 16th century, the finger in question became a marker of belonging. Certain Reformed movements explicitly recommended wearing the wedding band on the left ring finger, in defiance of established Roman usage.
Europe gradually split: the areas that underwent the Reformation adopted the left, while part of the Catholic and Orthodox worlds kept the right. The current map still bears the trace of this, even if no one thinks about its origin anymore.
The role of national codes and monarchies
Royal courts subsequently solidified these customs. A royal wedding protocol observed by an entire nation does more for a custom than any text.
Germany illustrates the result of these successive layers: engagement on the left, marriage on the right, with a single ring that changes hands. This switch is the vestige of a compromise between two traditions.
What it changes when you travel
In concrete terms, nothing. No one will ask you to change hands when crossing a border, and both customs meet in every major city.
One practical point, however: if you plan to wear the ring on the right, have your right finger measured. That is the only real consequence of this history, and it is the one most often forgotten.
The wedding day, minute by minute: where to put which ring
On the big day, the choreography of the rings plays out in a few seconds, in front of everyone, and no one has practiced it. Here is the complete breakdown so you don't have to improvise.
The day before: preparing the two rings
Have the engagement ring cleaned a few days before, not the night before. Jewelry returned from the workshop sometimes needs to be worn for a day to ensure it sits comfortably.
Take the opportunity to have the prongs checked. A stone that moves slightly can be fixed in ten minutes by a jeweler, but becomes a tragedy if ignored.
The morning: the ring moves to the right
If you are following tradition, move the engagement ring to your right ring finger before you leave. The left ring finger should be bare at the moment of the exchange.
Do this early, with a clear head. It is exactly the type of detail one forgets in the rush of the last few minutes.
During the ceremony: the wedding band alone
The wedding band is placed on the free left ring finger. A practical tip: slide it only to the second knuckle in front of the assembly, then adjust it yourself afterward.
Stress, heat, and emotion make fingers swell. A ring forced to the base in front of a hundred people is an unpleasant image to keep of your wedding.
Just after: the engagement ring returns
Once the ceremony is over, place the engagement ring back on the left ring finger, over the wedding band. This is the traditional order, with the wedding band remaining closest to the heart.
Nothing forces you to do it within the minute. Many brides wait for the cocktail hour, which is calmer, and keep the ring on the right during official photos.
The evening and the days following
Before dancing, check that the two rings are not overlapping crookedly. Rubbing all evening against a high-set stone leaves visible marks.
In the days that follow, a simple gentle cleaning is enough to remove traces of hairspray and lotion. Our guide on how to clean gold jewelry details the safe method.
Wearing your engagement ring as a necklace: when and how
This is neither an admission of failure nor a breach of tradition. Wearing your ring as a pendant is an old, common, and perfectly accepted solution.
However, it must be done correctly, as a poorly suspended ring is damaged more quickly than one worn on the finger.
Situations that justify it
A job that prohibits rings, pregnancy, an injured finger, intense sports, travel in a zone where you prefer to remain discreet: there are many legitimate reasons.
There is also the case of an inherited ring that is too big or too fragile for daily wear, which one wishes to keep close without risking it.
Choosing the right chain
The chain must be stronger than one might think. A chain that is too fine will open under the weight of a ring, especially if it is massive or paved.
Prefer a cable or Venetian chain of a suitable diameter, with a lobster clasp rather than a simple spring ring. Also check the compatibility of metals: a white gold ring on a silver chain will eventually leave marks.
Precautions to take
Always remove the necklace to sleep and for sports. A ring that swings against the sternum all night wears down, and a chain that gets caught in clothing snaps immediately.
Pregnancy, weight gain or loss: managing a finger that changes
A ring size is not a fixed measurement. It fluctuates with the season, the time of day, diet, physical activity, and major life stages.
Understanding why prevents panic, and above all, prevents resizing the ring at the wrong time.
Why fingers change volume
Heat dilates the tissues: a comfortable ring in January may be tight in August. Salt, altitude, a long flight, or a short night's sleep produce the same effect in the short term.
Conversely, cold and rest make the finger shrink, and a perfectly adjusted ring starts to spin. These variations are normal and do not justify any intervention.
Pregnancy
Swelling of the hands is very common during pregnancy, often starting in the second trimester and especially in the final weeks. Many women remove their rings long before they are forced to.
The right reflex is to anticipate: remove the ring while it still slides off easily, rather than waiting for the day it no longer moves. This is precisely the situation where wearing it as a necklace makes perfect sense.
Fingers generally return to their usual volume in the weeks following childbirth, but not always to the exact size as before. Wait several months before considering permanent resizing.
Lasting weight loss or gain
Significant weight fluctuation changes finger size permanently. A ring that spins constantly eventually wears down on one side and becomes deformed.
Here too, patience: wait for your weight to stabilize for several months before resizing. A ring that has been enlarged then shrunk twice loses material and strength.
Temporary solutions
For a ring that has become too big, the addition of an interior spring or comfort beads by a jeweler is reversible and discreet. Make-shift solutions glued to the inside of the ring should be avoided at all costs.
For a ring that has become too small, no trick replaces a visit to the workshop. Never force it, and above all, do not sleep with a ring that leaves a mark.

The complete symbolism of each finger of the hand
We summarized the symbolism of the five fingers above. It is worth expanding upon, as it still guides many choices, including engagement rings worn on fingers other than the ring finger.
This interpretation comes from a mix of ancient traditions, old astrology, and social customs. It is not scientific, but it is coherent and widely shared.
The thumb: willpower
The thumb is associated with strength of character and independence. It is the finger of action, the one that opposes all others and makes the human hand so unique.
People wear wide, flat, bold rings on it. An engagement ring does not traditionally belong there, but nothing forbids it on a very understated design.
The index: authority
The index finger points, orders, and indicates direction. It is historically the finger of power: ecclesiastical rings and signets were worn there.
In the Jewish tradition, the right index finger is also the one that receives the ring during the marriage ceremony. An index ring is immediately noticeable, as it is the most exposed finger to the gaze.
The middle finger: balance
Central and the longest, the middle finger symbolizes measure, responsibility, and the relationship to time. It handles massive pieces well, precisely because it is the most robust.
It is also the most frequent "fallback" finger: when the ring finger can no longer wear a ring, many move it here first, as the ring size is often similar.
The ring finger: commitment
The ring finger is, in classic symbolism, the finger of creation and emotional bonding. It is the least autonomous finger of the hand, the one that moves the least on its own.
This physical dependence is not without significance in the symbol: it is the finger that does not function in isolation, the one that needs the others. It is hard to find a better image for a commitment between two people.
The pinky: communication and heritage
The little finger is associated with communication, negotiation, and family transmission. It is the finger of both the heraldic signet ring and the contemporary pinky ring.
It accommodates both a discreet, antique piece and a very visible ring. It is probably the freest finger of the hand when it comes to style.
Left hand, right hand: two interpretations
In the most widespread symbolic interpretation, the left hand expresses who we are and what we receive; the right hand expresses what we do and what we give.
It is a pleasant framework, but it has no normative value. No symbolism should make you wear a ring on a finger where it makes you uncomfortable.
Engagement ring and work: professions concerned
For many people, the real constraint is neither tradition nor country, but their employer's internal regulations or the demands of their position.
Here are the major professional families concerned, and the solutions that truly work in everyday life.
Healthcare
Hand hygiene protocols are incompatible with wearing rings, even under gloves. A ring retains moisture and prevents correct hydro-alcoholic friction.
The universal solution in this sector is to wear the ring as a necklace during work, with it stored safely when not in use. It is also the safest: a ring left in a lab coat pocket always ends up disappearing.
Food industry
In cooking and baking, there is a dual constraint: food hygiene and safety. A claw catching on dough, a ring slipping into a preparation—these are incidents known to all chefs.
Here too, removal is the rule. Many professionals adopt a simple, smooth metal band for service, and keep their set ring for personal life.
Industry, mechanics, construction sites
This is the sector where the risk is most serious. A metal ring caught on a moving part or scaffolding can cause a serious finger injury.
No precious jewelry should be worn in this environment. Flexible silicone bands, which give way under tension, are designed exactly for this scenario.
Sports and the gym
A bar, dumbbell, or gymnastics ring crushes the bottom of the band and deforms the circle. On a pavé ring, this causes stones to loosen.
Always remove your ring before training and store it in a pouch, never loose in your bag. The gym is where the most rings are lost.
What works in practice
Three solutions cover almost every case: a necklace during service, a flexible replacement band, and wearing it on the non-dominant hand outside of work.
The choice of metal also plays a role. A harder gold stands up better to tough days, a point we compare in our article on 14K vs. 18K gold.

Broken engagement: what happens to the ring?
This is a difficult question to ask, yet it is one we are regularly asked. Let us address it simply, without drama and without lecturing.
Important clarification: we are jewelers, not lawyers. The following describes observed customs, in no way a rule of law.
First and foremost a human question
In the vast majority of breakups, the question of the object is settled between the two people, without outside intervention. The piece of jewelry crystallizes a lot of emotion, and it is better to let a few weeks pass before deciding.
A very practical piece of advice: store the ring in a jewelry box, in a safe and neutral place, while you reflect. A decision made in the heat of the moment regarding a valuable object is often regretted.
Observed customs
Three outcomes recur. Some people return the ring, considering that it was tied to a promise that did not result in marriage. Others keep it, wearing it on another finger or simply storing it away.
A third path consists of transforming the jewelry: the stone is remounted on a pendant or a cocktail ring, and the object changes meaning without being lost. This is a process enabled by our bespoke creations.
Where to get serious information
If the question becomes legal or patrimonial, do not rely on any blog post, including this one. Situations depend on the specific circumstances of each couple.
The reliable entry point for official information is service-public.fr. For aspects related to purchasing and consumer affairs, economie.gouv.fr also publishes up-to-date information.
Superstitions surrounding the engagement ring
Around such a charged object, beliefs abound. They are based on nothing, but they sincerely worry many people, so it is best to address them frankly.
Our position is simple: none of these superstitions have any basis, and most actually hide a real piece of practical advice.
Dropping the ring
Belief has it that a ring dropped during a proposal or ceremony heralds difficulties. In fact, it is a commonplace incident experienced by countless happy couples.
The real risk is material: a stone that hits a hard floor can chip, and a ring dropped on old parquet can disappear into a gap. Pick it up, inspect the stone in the light, and move on.
Letting someone else try it on
We often hear that an engagement ring tried on by someone else "brings bad luck." This idea has no basis, but it has a concrete justification.
A ring passing from hand to hand risks getting stuck on a thicker finger or falling. If you want to show it off, it is better to have it admired in the palm than on someone else's finger.
Removing your ring
Some people feel uneasy about the idea of taking off their ring, as if the gesture weakened the commitment. This is obviously unrelated: the commitment is not in the metal.
Removing your ring for washing up, baking, gardening, swimming, or applying sunscreen is actually the best service you can do for it. Chlorine and household products tarnish metals and gunk up settings.
What to remember
Behind every superstition hides a forgotten material precaution. Interpret them this way and they become useful instead of anxiety-inducing.
The only ritual that matters is regular maintenance. A gentle bath and careful drying are worth more than any good-luck charm, as we explain for silver in cleaning your silver jewelry.
How to precisely measure ring size, method by method
The right finger is useless without the right size. Here are the four truly reliable methods, from the most precise to the most improvised.
In all cases, measure the exact finger that will wear the ring, on the exact hand, at the end of the day and at a normal temperature.
Method 1: The ring sizer
This is the reference method, the one used in workshops. A ring sizer is a set of calibrated rings that you try one after the other until you find the one that passes over the knuckle without effort and does not turn freely.
The right size is the one that slides on and resists very slightly when being removed. If the ring comes off on its own when shaking your hand, go down a size.
Method 2: The paper strip
Cut a strip of thin paper about a centimeter wide, wrap it around the base of your finger, mark the point where it overlaps with a pen, then unfold and measure with a ruler.
The length obtained in millimeters corresponds directly to the French size. A finger circumference of 52 millimeters gives a size 52. Measure three times and keep the median value.
Method 3: The reference ring
If the person already owns a ring they wear on the intended finger, this is the most discreet solution. Measure the inner diameter in millimeters, then multiply by 3.14 to obtain the circumference.
Beware of the classic trap: a ring borrowed from the index or middle finger says nothing about the ring finger. Always check which finger the reference ring comes from.
Method 4: The string
This is the emergency method, the least precise. String stretches, pulls tight, and twists easily, which can easily throw off the measurement by half a size.
If you must use it, take a non-elastic string, do not pull too tight, and double-check the result with a second measurement made with paper. All FR, US, and UK conversions can be found in our jewelry size guide.
The most common errors
Measuring in the morning, measuring after sports, measuring in cold weather, measuring the finger of the other hand: these are the four main causes of a ring that doesn't fit.
A final point often overlooked: the wider a ring is, the larger it must be. A wedding band seven millimeters wide often requires half a size more than a thin ring for the same finger.
If you are hesitating between two sizes for a diamond ring for women, always take the larger one. Shrinking a ring is almost always simpler than enlarging it.
FAQ — engagement ring finger
Which finger do you wear the engagement ring on in France?
On the ring finger of the left hand, the fourth finger from the thumb. It is the same finger that will receive the wedding band on the day of the wedding.
Does the engagement ring go on before or after the wedding band?
Tradition places the wedding band at the base of the finger, closest to the heart, and the engagement ring on top. Many women today reverse this order for reasons of comfort.
Why the left ring finger and not another?
The Romans believed that a vein, the vena amoris, connected the left ring finger directly to the heart. Anatomy has debunked this belief, but the custom has remained.
Can you wear the engagement ring on the right hand?
Yes, without any problem. It is even the norm in Spain, Poland, Russia, or Greece, and a common choice among left-handed people in France.
What if the ring no longer fits on the ring finger?
Never force it. Run your hand under cold water, soap it, and rotate the ring while pulling gently. A professional resizing at a workshop will definitively solve the problem.
Do men also wear an engagement ring?
Increasingly, yes. It is worn on the same finger as their partner's, and generally adopts a wider profile and a more sober aesthetic.
Which finger should you wear your engagement ring on during pregnancy?
As long as the finger allows it, the left ring finger remains perfect. As soon as the ring becomes difficult to remove, take it off without waiting and wear it on a necklace on a sturdy chain, then wait several months after childbirth before any resizing.
Can you wear your engagement ring as a necklace?
Yes, it is an old and perfectly accepted solution, widely used by healthcare workers and those in the food industry. Choose a sturdy cable or Venetian chain, a lobster clasp, and take the necklace off for sleeping and sports.
What happens to the ring in the event of a broken engagement?
In practice, the question is settled between the two people: return, keep, or transform the jewelry into a pendant or cocktail ring. We are jewelers and not lawyers: for any legal questions, refer to the official information at service-public.fr.
In summary
In France, the engagement ring is worn on the left ring finger. Elsewhere in Europe, the right ring finger is just as legitimate. No rule is mandatory.
What really matters is that the ring is the right size for the chosen finger, that it does not hinder daily activities, and that it cohabits well with the future wedding band.
