I like the site, it's easy to navigate. There are sometimes items I'm looking for that aren't there, but mostly I can find what I need.

I enjoy doing buisness with GemSelect. It is always a pleasure and you get what you ordered!

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.
