We are thrilled to introduce a new series of gem auctions.  We will be 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 superb mix of well-known, rare, unique and collector quality gems with reserve bids starting at $10 up to $999.  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.
