Gemstones For Sale

What makes us different to other websites selling gemstones? Most importantly, our Gemstone Sheriff program is unique to Gem Rock Auctions. It is the industry’s first program to review any gemstone sold online to make sure it’s natural. A panel of independent gemologists reviews any item upon customer requests. This program ensures a high level of item accuracy. We are proud to say that we have not sold a synthetic or man made gemstone since .

Second all of our sellers are handpicked and approved by the Gem Rock Auction team. The sellers must have extensive product knowledge, customer service skills, and they have to have a passion for the gemstone industry. Any vendor approved to sell on our website has been vetted in order to become one of our Verified Sellers.

Plus, we have no-reserve gem auctions available, also known as absolute auctions, where the sale will be awarded to the highest bidder. Alternatively, you’ll have the convenience of placing a bid or you can decide to “buy now” if you prefer. Our gemstones dealers are dedicated to providing you with every opportunity to make a wise and exciting purchase.

Online Gem Auction Categories

We have organized each Auction in to categories by gemstone so that it is easier to find the mineral you are looking for. For example, single faceted stones can be found under the Gemstones category and any rough material can be found under the Rough category.

There is a special category for matched Pairs of gems for sale because these can difficult to find when you’re customizing a specific piece of jewelry such as earrings. Specimens is a special category for items that are still in the rough state but are not suitable for faceting. These specimens are perfect for seeing how the natural stones form.
