All sellers on Gem Rock Auctions must comply with our Verified Sellers program which ensures a high degree of industry knowledge, consistent refund policy and wholesale pricing.
The Gemstone Sheriff program allows our members to request an audit on any auction, which is completed by an independent gemologist who assesses the accuracy of the item description and pictures.
