Colby Covington got himself a sweet pre-fight treat this week ... coppin' a $50,000 diamond chain featuring his nickname, "Chaos," before his massive scrap with Jorge Masvidal.
TMZ Sports has learned ... the MMA star hit up Boodaddy Diamonds to get the piece made prior to his headline fight at UFC 272 -- and the celeb jeweler delivered big time.
We're told the pendant features 14k solid gold, over 15 carats of VVS diamonds, and comes with a crown bale just over the "A" in CHAOS.
We're also told the tennis chain that supports the pendant has 28 carats of VVS diamonds. And, based on the pics of Colby with the chain, it's clear the dude loves it.
The drip is pretty and will look great in the pre-fight leadup ... but one thing seems for sure, his feud with his former friend-turned bitter rival is the exact opposite.
The two mixed martial artists hate each other ... and Covington told us just a few days ago the tension between him and 37-year-old Masvidal is VERY real.
In fact, Covington called it "a blood feud."
No word on if Colby will be sporting the new chain the night of the big fight ... but expect plenty of "chaos" when the two finally get their hands on one another.
