Boston Celtics star Jaylen Brown is fresh off a brand new, $115 MILLION deal … and if that's not sweet enough, the baller got a sick, $20k chain from his good buddy, A$AP Ferg!!
TMZ Sports has learned … the "Floor Seats" rapper wanted to do something extra special for his friend's birthday, so he hit up Big Will at WS Jewelry and the guys collabed to make him a one-of-a-kind piece.
We're told the piece comes with 15 carats of natural green and white diamonds shaped in Ferg's signature logo … and it's worth around $20k.
The back of the pendant also features Jaylen's jersey number, 7, and his name.
The video is awesome … Ferg and Big Will were there to celebrate with Brown … and the dude had a BIG smile on his face when they presented him with the present.
