Post Malone is celebrating a new addition to his already impressive jewelry collection -- a blinding 23 carats worth of diamonds, and all that bling is just for the littlest finger of them all.
Guess his hand was feeling a little light, because sources close to Post tell TMZ ... he called up his pals at Angel City Jewelers to hook him up with a new piece for his pinky.
Angel City's owner, Isaac Bokhoor, came through with the goods while PM was making a recent tour stop in Las Vegas ... and unveiled the "Rockstar" sized ring ... which we're told set the singer back about half a million bucks!
For that kinda dough, ya better love it ... and Post clearly does. Check out his reaction right after getting it backstage -- you're looking at a 5-carat Emerald cut center stone, with another 5 carats of round diamonds on the side. There are 13 more 1-carat stones around the band.
Of course, the "White Iverson" is no stranger to getting blinged out by Isaac and co. -- remember, he was the master behind Post's $250k Dallas Cowboys chain.
He got it back in 2019, appropriately while he was in Dallas at AT&T Stadium. That one came with 3,000 stones, 9.7 carats of baguettes, 13.5 carats of sapphires and 8.7 carats of diamonds.
As for the new pinky ring, Post couldn't look happier -- that is, unless his Cowboys win a Super Bowl. Until then, the diamonds should keep him smiling.
