Pop's inner circle reached out to New York City's Benny The Jeweler for some special commemorative bling ... according to our sources, and it was just in time for Friday's posthumous release. Ya gotta see what @bennydajeweler cooked up in Pop's honor.

Check out the 5 "Woo Star" pendants for the guys over at Forever Smoke Entertainment ... the record label founded by Pop's brother, Mike Dee, along with Ace Makaveli, Eazy, Stacks and Hunter.

There's a rose gold pendant and 4 yellow gold pendants ... and they're covered with 20 karats of VS diamonds, retailing at a cool $18,000 each. We're told the bling represents rising above adversity, as well as shooting for the stars, and aiming for the moon -- the title of the album.

Pop's girlfriend, Alyssa Danielle, is also getting some special jewelry from Benny ... an insane custom piece featuring Smoke's face surrounded by diamonds. We're told it's still in the works, and the finished product will be super colorful.

The sad news is Benny was working on a couple pieces for Pop himself before the rapper was fatally shot in February in a home invasion.

Remember, fans demanded a do-over of the cover art Virgil Abloh designed for "Shoot for the Stars, Aim for the Moon," and they're getting their wish.
