I was looking for high-quality amethyst on this site, and I was able to compare size, color, and weight in detail before making a purchase.

I needed a very specific color of tourmaline and Gem Select had it. I had to get the client to agree and then ordered the stone. It arrived better than pictured and we all were very happy.

Wonderful experience so far. I rarely order from vendors online but Ia'm hoping the gem I ordered is of good quality and not a fake.

Always find more niche sizes/shapes as my unconventional designs require from this website. Recommending to fellow designers in the creative atmosphere on the usual, specially due to the quality and certification of gems.
