Special Denver 2023 Show Auction!

To lead up to the Denver show, we are pleased to present a very fine set of mineral specimens for online auction, featuring numerous beautiful specimens from new finds and old discoveries. We've had many specimens out for cleaning during the last several years from collection purchases such as Currier, Trancoso, Larson, and Lockhart, and we've decided to feature many of them HERE, ONLINE, for you! We also included a few choice specimens directly from our gallery cases. Selected specimens from this auction will be available for viewing in person at the Denver show at the Arkenstone booth! See you there!
