Have made 2 purchases so far from GemSelect and they have been amazing! Anytime I requested additional info, videos or pictures of a particular item, the response was always timely and helpful. This is a great place to buy, if you are looking for loose stones. Highly recommend!

this site is awesome. I was able to look at the products think about purchasing and come back and find the same products. With the amount of inventory gem select has. Its awesome to be able to filter the way that they allow you too.

I liked the selection of gems, and price. I did not like your PayPal process. I already have a PP account and you want me to sign up for another.
