Continuing with our series of gem auctions, we are offering a selection of fine quality gemstones that we acquired from the inventory of a respected wholesaler with decades of experience in the gem business.

You will find a wonderful mix of well-known, rare, unique and collector quality gems with reserve bids starting as low as $10. Pay close attention to the quality in these auctions, as all of the stones are well-cut (many have unique custom cuts) and are not your typical "jewelry store" material. There are many gems in these auctions that one rarely sees on the market, and even the more common material is better than what you'll find in a lot of other venues.
