Tekashi 6ix9ine just unveiled his new multi-color grill and if you want one like his ... it's going to cost you a pretty penny.

We're told the new rainbow piece is actually made from 14-karat white gold, which is obviously expensive. The real art here is in the different color enamel applied by the celebrity jeweler Jimmy Boi (aka TheStreetsJeweler).

The $5,000 grill was made two months ago, but the "Billy" rapper took to social media today to show off his new bling.

The good thing is if 6ix9ine is successful in his bet with boxer Adrien Boner, he will be able to buy a rainbow grill for all his homies in Brooklyn.
