GemSelect Certified Store Reviews

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

Overall Rating -> 9 star ratings

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.

Great selection of gems at a reasonable price

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.

Very fast navigation and purchase, which is good. I need to strike while the iron is hot.

I am never let down by GemSelect. I love that you get the exact stone you want. Shipping is always in a few days. I have spread the word about GemSelect on social media jewelry creating groups that I attend. This sapphire is going to make one gorgeous ring

Always find more niche sizes/shapes as my unconventional designs require from this website. Recommending to fellow designers in the creative atmosphere on the usual, specially due to the quality and certification of gems.

Buy gems by weight. Shop from our extensive range of beautiful, natural 15-carat gems. Browse the largest selection of natural loose colored gemstones available in 15 carats. Our large gemstone selection includes many popular gem types, such as amethyst, citrine, topaz and turquoise, and lesser-known gems, including ruby-zoisite, ammolite and maw-sit-sit. From here, you can use our filters at the top or on the left-hand side to find gems by gem type, color, shape, cut and so on. For example, select 'tourmaline' to see all of our 15-carat tourmaline gems. Select 'multicolor' to shop for 15-carat multicolor gems. You can also filter by single, pairs, lots, faceted gems or cabochons by using the check boxes at the top.
