2 Chainz: But I Got Me a Few New Ones On ... Worth $65k

2 Chainz added a few more in an all out shopping spree at what sounds like his favorite spot in the world.

We got Tity Boi outside Avianne Jewelers in NYC, and you can tell from the video ... he was in the mood to do some serious shopping.

We spoke with owner Joe Avianne who told us Chainz left with a 25 karat black onyx stone ring outlined in diamonds, a 25 karat diamond tennis necklace, and an upgraded 30 karat diamond bracelet. Total damage -- $65,000.

We're guessing he was splurging to celebrate his new project with Lil Wayne, "ColleGrove."

As 2 Chainz would put it -- when he dies, bury him inside that jewelry store.
