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. Look for new goodies from Tucson along with new collection acquisitions to appear in the coming weeks. 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, Francesco Bedogne, Rolando Gioia, Charlie Key and plenty of pieces from Kay Robertson along with various dealers' inventories.
