It looks like Big Sean is treating himself to some new bling for having just turned 30 years old this weekend. TMZ reports that the Detroit rapper just bought himself a brand new $120,000 ring from NYC-based Avianne & Co Jewelers.

The ring, which costs as much as a small home or exotic whip, is made up of a stunning 4-carat Colombian green emerald centerpiece that's surrounded by 15 carats worth of VS diamonds, and it's reportedly heavy as all hell too on one's hand.

The news outlet says the ring was made in New York but it was delivered to Sean in L.A. before this past weekend’s birthday festivities went down. In case you missed it, Jay-Z, Beyonce, John Mayer, No I.D., and of course his girlfriend, Jhene Aiko, were all in attendance to help celebrate Sean’s birthday. Coincidentally, John Mayer is someone Sean has been recently spotted in the studio with, and has an upcoming collab on the way.

As for the new bling, I wonder how his girl Jhene feels about it all. Do you think she wants a ring on her finger next? Check out a clip of Sean’s new bling (below) and let us know you think. Look for new music to be on the way.
