First time using this website. It was both exciting finding things in my price range and things Iam gonna save up for and use in other pieces. I love that the picture of the gem is the exact gem I'll be buying. I haven't tested the gems yes but they said they sold me 100% natural gems.

Absolutely love the website, selection and products. Can you guys add a gemstones with inclusions tab. I like those it'd be nice to have them all in one place but i do understand it would be alot of work to go through and categorize them. Thank you anyways

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.
