GemSelect Certified Store Reviews

GemSelect: Over 22 Years in the Gemstone Business! Thank you for trusting us with your purchase!

Overall Rating -> 10 star ratings

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.

I purchased from you before and I have never been disappointed. I always received what I expected and your products are very nice.

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 love the gems and your website, every time I want to buy I usually spend between 6 and 8 hours on your website.

The site provided lots of detail, factual data, and good photos. I also like the availability of searching by price range as well as by the type of stone.

Nice website I just don't know much about the quality until I receive the stone.
