Avi The Gem Guy
Avi Rahmanim
Avi Rahmanim is a Chicago gemologist. He buys, grades and sells colored gemstones, diamonds and fine jewelry from the showroom at 5 S. Wabash Ave, Suite 1010. On YouTube, TikTok and Instagram he shows people exactly what they're buying, and he and his team design custom pieces around the stones they choose.
How we work
The standards behind the stones and jewelry we sell.
Every stone, graded
Each stone is examined individually. No catalog photos of stones you'll never see.
Treatments disclosed
If a stone is heated, oiled or otherwise treated, we say so, and back it with a lab report where there is one.
The exact stone pictured
What's in the photo and video is what arrives at your door.
Made with you
Custom work is designed with Avi and his team, and you approve every step.
On top of the great goods, Avi is a pleasure to deal with — made the transaction super easy from start to end.
