He got the G.O.A.T. rings ... now Antonio Brown is paying homage to the Greatest of All Time, Muhammad Ali, with an iced-out butterfly and bee chain worth $250k!!
TMZ Sports has learned -- the NFL superstar wanted to honor the legend and his AB nickname at the same time ... getting an insane bee with butterfly wings -- and his #84 jersey number on it.
We're told Brown went to his go-to guy, Gabriel the Jeweler, for the job ... hooking him up with the piece made with a combo of pear and baguette-shaped VVS and brilliant-cut diamonds, totaling 65 carats on the cuban chain and 50 carats on the pendent.
