Our best selling products. Blue spinel, peridot, amethyst, ametrine, chalcedony and garnet remain our best selling gems. We sell a lot of estate jewelry. This is due to the fine quality and rareness of the gems we obtain and pricing on our gems and jewelry. We also maintain our own award-winning USA gem cutters as well as represent some of the finest gem cutters in the world who allow us to set our own pricing on their gems often lower than buying direct from the cutter. We frequently batch-test our rough with GIA and if a gem is not certified we will send it to GIA or extremely rare gems to private laboratories for intensive testing and certification.
