The US Gemologists Institute is a United State & Canadian gemoligy labritory, founded to restore honesty, moral clarity, and accutate testing to the gemstone world.

We believe that every gem desersves to be seen truthfully and every person deserves to feel confident in its authenticity.

Our Mission is simple: to grade and certify gemstones with integrity, using the advanced tools and protocols that go beyond the norms (while staying current with the Labs tools and books), from short to long wavlenths to filter, screens and scopes, in a industry with zero room for error, we know the 3 C's, easy as slicing cheese.

Whether you're a collector, creator, seeker of truth, we exist to protect the bond between beauty and belief.

This is 1 of 2 Labs that have come together to give the people 1 of the most trusted gemstone stores.

The Gemologists Institute are Proud Lab Partners with Microsoft's Copilot and Nellis Lab.
