Overall Rating -> 10 star ratings

Would have bought an indigo and selenite, but neither listed. But, you do offer quite a large assortment otherwise.

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 love Gem Select! When you order what you see is what you get. As soon as you make payment that particular gem is taken off the photo album. That way the one you select is a one of that kind.

I've purchased from here many times over the last decade+. I find the information easy to understand, helpful, and interesting. I have always been satisfied that I got exactly what I ordered. Pictures and descriptions are clear and unique to each stone.

I searched for the size, dimensions and quality of the stones I was looking for and then compared and ordered.
