Nate Diaz is giving his fighters a helluva welcoming gift ... 'cause he hooked 'em all up with iced-out pendants to make sure everyone knows they're the "Real" deal!!
TMZ Sports is told ... the MMA legend reached out to the famous Icebox shop to get something special for the folks who joined the Real Fight Inc. promotion he launched in 2022.
We're told he ordered a total of seven two-toned pendants ... and each comes with just under 10 carats of VS diamonds and over 50 grams of gold. The pieces also come with a matching 14K gold rope chain.
Unsure which fighters will get the new bling ... but the badasses listed on Real Fight Inc., excluding Diaz, are Chris Avila, Alan Sanchez, Jose Aguayo and Luciano Ramos.
Diaz -- who last fought Jake Paul in August -- is taking his promotion very seriously after he left the UFC last year ... saying his goal is to focus on boxing, MMA and BJJ.
"I said when I get out, I was going to do my own promotion like Jake was doing with Most Valuable Promotions (MVP)," Diaz said on Full Send.
"Well, I just jumped right in, and I felt like the business was mine the whole time."
He also stated the new business won't interfere with his status as a fighter ... most recently claiming he wants a rematch with Paul in December.
