United Color Gems, Inc.

Feb 2026

I have been a very loyal customer of UCG for well over 14 years, primarily purchasing the very top grade Tanzanite and some ring semi-mounts. The Tanzanite solitaires I’ve purchased are AAA grade with perfect colors…deep royal blue with flashes of purple and red. All first class. We do business primarily at the AGTA Tucson Gem Faire, and I always make a bee-line right to Raj’s booth, opening day. The day I stop purchasing from them will either be my retirement or death! I love this company and all of it’s knowledgable employees! ❤️ (The attached photo is the large Tanzanite pendant I designed with the gemstone from United Color Gems.)
