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

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.

I have bought from you before and have found your gems exceed my expectations. I have been very satisfied with all gems sent to me. I will be back. Thanks....

I was looking for a small gift for a friend- the process is the same as every other time and was very simple, and she even got her gift early! On the downside, there's no way to easily keep track of multiple Shipping Addresses, so if I want to send a gift to Friend A and to Friend B, I have to overwrite everything and it's a fair bit clunky in that regard.

I always enjoy the selection and the unique cuts I can find here. I would love to see more hex cuts tho! Maybe some rose cuts too!

All these questions, and I don't have to give any blood. What a Deal... I absolutely enjoy the Gem Select emails every month. This one today was special. I always say, I'll know it when I see it. This stone today was the One. Odd and Intriguing. Thank You So Much for all that you do.

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.
