Details Materials, dimensions, tips

Voici une chaîne cubaine pour homme qui ne joue pas la carte du pavage lisse. Ses maillons de 20 mm sont des grappes de diamants de laboratoire sertis clos : un relief dense, presque minéral, qui change d'aspect à chaque angle.

Le modèle : une maille cubaine tout en volume

Sur la photo à plat, on distingue nettement la construction : des pierres rondes cerclées de métal, regroupées par petits ensembles qui forment les maillons croisés de la cubaine. Le contour de chaque sertissure est finement perlé. Le fermoir, large et bombé, dessine une rosace entièrement pavée.

Comment porter une cubaine de 20 mm

Notre modèle la porte à la base du cou, sur un tee-shirt noir : le relief se détache parfaitement. C'est le rendu d'une longueur courte, 45 ou 50 cm selon votre tour de cou. En 55 ou 60 cm, elle prend un tombé plus souple, à porter sur un sweat ou sous une veste.

Diamant de laboratoire : mêmes propriétés, autre origine

Le diamant de laboratoire est du carbone cristallisé, comme le diamant de mine : dureté de 10 sur l'échelle de Mohs, éclat blanc, réaction positive au testeur de diamant. Associé au serti clos, où le métal entoure chaque pierre, il donne une chaîne faite pour être portée souvent.

Métaux et longueurs

Métal au choix À retenir
Argent 925 Argent sterling, blanc et vif, tarif le plus léger
Or 10K 41,7 % d'or pur, alliage très résistant au quotidien
Or 14K Or à 14 carats (58,5 %), le compromis le plus choisi
Or 18K La teneur en or la plus haute de la fiche, reflet intense
Longueurs possibles 45, 50, 55, 60 cm
Finition Or jaune, or blanc ou or rose. La finition se choisit sur la fiche et s'applique aussi à la version en argent 925

Le prix se calcule selon le métal et la longueur retenus.

Questions fréquentes

Quelle différence entre un serti clos et un serti griffes ?

Le serti griffes tient la pierre par de petites pointes de métal ; le serti clos l'entoure d'un bandeau continu. Le second protège davantage la pierre.

Une chaîne de 20 mm, est-ce trop large ?

Non si vous la portez seule, sur une tenue sobre. Pour comparer avec des largeurs plus modestes, parcourez la collection chaîne cubaine.

Diamant de laboratoire ou diamant naturel pour une chaîne homme ?

Les deux sont des diamants. Le naturel ajoute la rareté ; le laboratoire, la même matière créée par l'homme. Ce modèle existe en diamant naturel.

Care Keep the shine, day after day
  • Remove it before water. Shower, pool, sea, sport: chlorinated or salt water tarnishes the metal and weakens the settings.
  • Perfume and cream first. Apply them before putting on your jewellery, never after.
  • Store it separately. In its jewellery box or a pouch: jewellery that knocks together gets scratched.

Moissanite and diamonds

Soak in lukewarm soapy water, gently brush around the setting, rinse thoroughly and dry immediately.

Or 10K, 14K, 18K

The purer the gold, the softer it is: clean it with soapy water and have it polished from time to time by a jeweller.

Argent 925

It can oxidise slightly in the air: a special silver cloth or a bath of lukewarm soapy water restores its shine.

All our care tips

EMIR LUXE

Three stones, three reasons to choose

The price of a piece depends first on its stone and its metal. Here, simply, is what distinguishes the three stones in the range.

Moissanite

Type
Synthetic stone (silicon carbide). It is not a diamond.
Hardness
9.25 out of 10 (Mohs scale)
Brilliance
Very lively fire, with more pronounced coloured reflections than those of diamond.
Who it is for
Maximum brilliance for the most accessible budget in the range.

You are viewing this version

Lab-grown diamond

Type
Real diamond (pure carbon), created in a laboratory.
Hardness
10 out of 10 (Mohs scale)
Brilliance
The same as a natural diamond: same material, same properties.
Who it is for
A real diamond, without the price of rarity.

Natural diamond

Type
Real diamond, formed in the earth then extracted.
Hardness
10 out of 10 (Mohs scale)
Brilliance
The benchmark against which all other stones are compared.
Who it is for
The rarest stone, for a piece that is handed down.
