Easy to use. No issues. Large selection of gems.
Overall Rating -> 10
My experience has always been fantastic. Today I saved 6 gems to email a customer looking for a particular color blend to fit into an east west setting, so her options were limited, but we found one she wanted, deleted all the others in the cart and order the gem she selected. It was helpful to be able to put them in the cart so I could save them until she selected the one she wanted without having to research all of them again.

I had a very easy time navigating the web page and using filters to find what I was looking for. The varied selection was nice to see and pricing is clear and fair.

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.
