I have purchased stones from gem select in the past and have been very satisfied. I expect to repeat that experience with this purchase as well

I love the quality, presentation and the price of the stones. I love the identification card - report they send with each stone.

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.
