Although the stones are smaller than I thought, I really don't think in millimeters, they are perfect. I plan to put one into a ring and the other into a necklace. Ordering was easy, contact kept me aware of how shipping was going, and delivery was sooner than expected. The quality of stones I have ordered in the past and this recent order is outstanding and stones I will be proud to wear.

Easy picking, fast checkout, secure shipping. Cana't ask for anything more than efficiency and a good price.

I love the ability to choose from many options of shapes, gemstone type, color, and so forth. It is fun!

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.

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.
