WEEKLY MINERAL & GEM AUCTIONS!

Filter By
Current Auctions

Continuing with our special themed auctions we have a selection of higher-end minerals this week with $999 reserve bids. A great opportunity to pick up excellent pieces for bargain prices! You'll find a great mix of fine quality specimens from new and contemporary discoveries plus classics and showy display specimens!

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.

Thanks for exploring this year's Dallas Symposium Benefit Auction, closing on SATURDAY, August 20th at 5:30 PM CT. Auction proceeds benefit Mineralogical Record, Rocks & Minerals, Tucson Gem and Mineral Society, and mindat.org
