Gem Auction - Worldwide Stones

A great mix of assorted worldwide gemstones. You will find an interesting selection of well-known, rare, unique, and collector-quality gems with reserve bids starting at $10 up to $249. Pay close attention to the quality in these auctions, as all of the stones are well-cut (some 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.
