Mr. OVO is the new owner of what soon will become 2 of America's most wanted ... these Tupac pendants dripping with diamonds and gold. The rapper commissioned the celeb jeweler, Jason of Beverly Hills, to pull off the twin pendants depicting Pac with white and yellow diamond crowns of thorns.

Each pendant comes with a diamond chain with a total of approximately 70 carats of flawless white and yellow diamonds, plus ... over a HALF KILO of gold in total. Total price for each piece was $300k!!!

We're told Jason and his crew spent about 5 weeks completing the Pac-Jesus pieces. Drake initially came to Jason with an idea about what he wanted ... and they worked together to come up with the final tribute.
