GemSelect Certified Store Reviews
GemSelect: Over 22 Years in the Gemstone Business! Thank you for trusting us with your purchase!
Overall Rating -> 9 
the gems were smaller than I thought but I was at fault for not reading the complete discrimination
Overall Rating -> 10 
I've made several purchases through GemSelect in the past, although not within the last six months. Their gems are always beautiful and I have never had an issue with their prices or their stones. Even when I'm not buying, I love scrolling through their website, which is very user friendly. I especially appreciate being able to change the listing order to your own liking, such as most to least expensive, largest to smallest, etc. As with most online orders, however, I think the shipping charges are not commensurate with the actual weight of the items shipped.

great experience
Overall Rating -> 10
Im not a jeweler, I buy for my personal use. My dad was a jewelry maker and I love gemstones.
Overall Rating -> 10
I like the site, it's easy to navigate. There are sometimes items I'm looking for that aren't there, but mostly I can find what I need.
Overall Rating -> 10
I searched for the size, dimensions and quality of the stones I was looking for and then compared and ordered.
Overall Rating -> 10
Nice website I just don't know much about the quality until I receive the stone.
Overall Rating -> 9
Site is easy to navigate - details on cut, polish, and finish work and techniques were helpful. 3d view or wireframe diagram of stones would be nice.
