Post Malone has come a long way since the release of his debut album, and the same can be said for his jewelry collection. Recently tapped by GQ for a new episode of its wildly popular series On the Rocks, the artist proudly showed off his favorite pieces, from watches to rings to a handful of chains. If the pair of iced-out Hello Kitty jewelry from his first GQ On the Rocks interview was a testament to craftsmanship, the newest addition to his collection is on a whole new level of artistry and bling.

Dressed in a purple shirt and pants, the Sunflower singer showed us his favorite things, describing each piece in his usual manner. He begins with three of his watches, saying, "I spend a little too much money on watches; I feel like watches are a great investment." He adds that factory diamonds and super rare collectibles are what he always seeks out and buys—he plans to give them to his child later.

The first watch he chooses is his Rolex Rainbow Cosmograph Daytona, which he describes as unique and elegant, "but it jumps out at you and says, 'Hey, look at me.'" He then shows us one of his Patek Philippe pieces, the khaki green Aquanaut, which he says he's lucky to have because a good friend helped him get it. It's clear he loves the luxury brand; he chooses another Patek piece to present next: a factory Nautilus with three baguette diamond hour markers, 100 diamonds on the case, and 255 diamonds on the dial. This piece is a true iced-out masterpiece, with a total of 1,343 diamonds.

Speaking of diamonds, the Grammy nominee takes a break from his watch collection and briefly discusses his two rings. The first is an Isaac ring from Angel City Jewelers, which the singer claims he wears on his opposite ring finger to marry himself, stating that no one will ever love him the way he loves himself. The second is an invisible-set baguette ring made by Richie Rich, which he calls cool and awesome, adding that he likes to wear it on his pinky because of its large size.

Post Malone then continued to show off the rest of his watch collection, choosing a Richard Mille RM12 Tourbillon, his lightest tourbillon to date. He described it as so light that "it makes me feel like an astronaut." He owns two other Richard Mille watches, a white ceramic RM55 Bubba Watson, and his most expensive watch, a Skull Asia Edition watch that has 19 jewels and costs $1 million.

The Billboard Music Award winner also owns other notable timepieces, such as his Rolex Rainbow Daytona Cosmograph and an Audemars Piguet Royal Oak. He also owns a pair of Hublot watches: an 18-karat white gold Ferrari tourbillon chronograph with a sapphire case and dial, and a Skeleton tactical watch, which he likes to wear when he's at home in Salt Lake City.

The rest of his jewelry collection consists primarily of white gold pieces. The American Music Awards winner is apparently a big fan of white gold, but he also enjoys rose gold jewelry, and particularly appreciates anything baguette, from chains and pendants to watches and rings.

It's clear that Post Malone isn't just a man who knows what he wants and how to get it; he also knows how to fully appreciate and care for what he buys with his hard-earned money. Regarding jewelry purchases, he advises, "Make sure you think it through, make sure you know what you want. Take care of it; keep it nice and clean."
