We have a great selection of material that 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. We'll still have selections from various collections we've obtained including Willard Wulff, Rolando Gioia, and plenty of pieces from Kay Robertson along with various dealers' inventories.
