Sold Auctions
Hi! Welcome to Gem Rock Auctions. If you are looking for loose gemstones, gemstone rough, mineral specimens, Birthstones, Diamond, Sapphire or anything else to do with gemstones than this is the place to be. Gem Rock Auctions is a global marketplace where sellers from all over the world who have been verified and approved can sell their gemstones direct to you.
What makes us different to other websites selling gemstones? Two main things set us apart.
- All of our sellers are handpicked and approved by use. They must have product knowledge, customer service skills and most importantly they must have a passion for the gemstone industry. We call them our Verified Sellers.
- Our Gemstone Sheriff program is a world first. A panel of independent gemologists review any items that a customer requests to be reviewed. This program ensures a high level of item accuracy and we are proud to say that we have not sold a synthetic or man made gemstone in over 5 years.
Birthstones
With the largest selection of Birthstones on the web you are sure to find the perfect gift. Find out what the birthstones are for each month here.
