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've made several purchases through GemSelect in the past, although not within the last six months. Their gems are always beautiful and I have never had an issue with their prices or their stones. Even when I'm not buying, I love scrolling through their website, which is very user friendly. I especially appreciate being able to change the listing order to your own liking, such as most to least expensive, largest to smallest, etc. As with most online orders, however, I think the shipping charges are not commensurate with the actual weight of the items shipped.

I did not realize these stones were of jewelry quality. They are really beautiful, just not what I was expecting which was more of a natural stone.
