Big Sean just bought a big ring, but it ain't for Jhene Aiko. He bought the ring as a birthday present to himself. For turning 30, Sean bought a 4 carat Colombian emerald that's surrounded by 15 carats of VS diamonds.
The ring was made in NYC and was delivered to him in L.A. just in time for his birthday party. Oh, how much was the ring bling birthday present?
It set Sean back $120K, or to put it in the simple words of TMZ, "he bought a G-wagon for his finger."
