Drake is showering himself with expensive gifts for his 33rd birthday ... dropping more than half a million dollars for a custom diamond ring in the shape of a heart.
Sources with knowledge tell TMZ ... the "Hotline Bling" rapper purchased a 22-carat, heart-shaped diamond ring from Gemma Fine Jewelry as a bday present to himself, and the piece is valued between $600,000 and $800,000.
As you can see, the diamonds are mounted in a platinum setting ... and we're told it's extremely difficult to make a heart-shaped ring of this size -- making this a very rare find.
As we reported ... Drake hosted a star-studded birthday bash at Goya Studios in Hollywood, partying with big celebs like Adele, Snoop Dogg, Kylie Jenner and French Montana.
Drake debuted his shiny new bling at the party -- what better occasion, right -- and on another finger he was rocking his customized $150K Toronto Raptors NBA championship ring.
Our sources say Drake was heavily involved in designing his newest ring, working alongside Gemma Fine founder Ori Vechler … and he's adding it to a growing collection of heart-shaped jewelry.
Yes, Drake loves him some Drake.
