POST-TUCSON SPECIAL MINERAL COLLECTION LIQUIDATION AUCTION - ends Thursday March 7, 2019

ends Thursday March 7, 2019
at 6:30 PM (Central Time Zone)

THIS AUCTION INCLUDES MANY OF OUR FAMOUS $1000-CASE LIQUIDATION PIECES from the Tucson Main Show. We're back from Tucson with a great selection of specimens. We have pieces set aside specifically for the auctions that didn't make it to the shows, along with new finds and old collections we've purchased. You'll find gem crystals, rare species, old classics, and many good specimens that are hard to find at any price, let alone at auction! Plus, we included a number of holdbacks from other old mineral collections we have liquidated, for a great variety of specimens including pieces worth $1000+, starting at only $10.


Some of the highlights from this week's include:

1. Rare PSEUDOMORPHS from the Ken Roberts Collection.
2. Superb POWELLITE on STILBITE from India
3. Rare STAK NALA species
4. Striking SMOKY QUARTZ/AMETHYST
