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!

Gem Select has a user friendly website and the product is very good as is the price. The gems are described accurately and I always get what I think I'm getting.

I am very pleased with the ways you can filter your searches on this site, finding exactly what I want with little knowledge of what I am looking for is surprisingly easy!

I was looking for a site with every type of gem I could want for setting in luxury blades and assumed I would need to look outside the US, but GemSelect made it easy to get everything I wanted without leaving the house! Wide enough selection that I do not feel the need to look elsewhere and pricing the same.
