Apparently, you don't gotta play a sport to rock a championship ring -- just ask Chris Brown ... who just dropped $100,000 to make his crew look like the '96 Bulls.
Brown hit up Elliott Eliantte of Eliantte and Co. in NYC and commissioned 15 rings for himself and his best friends ... a crew that calls themselves OHB (Original Hood Bosses).
Elliott tells TMZ Sports ... each ring is made with 50 to 60 grams of 14 karat gold ... and sports roughly 3 carats worth of diamonds.
But Brown put more ice on his ring -- the boss ring -- that one has between 10 and 12 carats worth of diamonds.
We're told Brown and the group are getting their rings today.
