This week's auction is filled with new material we picked up over the last few months along with rarities, unusual pieces, gem crystals, classics and display specimens. You'll even find a few fossils, carvings / lapidary items and gemstones mixed in every now and then. Look for pieces mixed in from various collections we've obtained including Willard Wulff, Kay Robertson, Francesco Bedogné, and Paul Zerfass, along with dealers' inventories. Look here for the not so typical mineral specimens along with plenty of your favorites. We don't just offer the "standard 20 species", but an eclectic mix of specimens that appeal to everybody! Enjoy!
