Gemmy single Chrome Tourmaline crystal, which is a chromium and vanadium rich Dravite. Intense, saturated green color. Undamaged, complete crystal. Small but a real gem of a crystal!!!!

Large Ajo Copper with a row of tall crystals to 13cm. The crystals formed in a  seam and the specimen has a uniform thickness it's entire length. This was in an old collection I bought and based on the other minerals in the collection, I estimate it's from the 1970s or 1980s. Reminds me of an old saw blade.

Spherical crystal groups of orange Orpiment and red crystals of Hutchinsonite on matrix. Hutchinsonite is a rare thallium sulfosalt species and these recently found red crystals are some of the best ever found. Crystals reach 7mm long.

Selenite and Chrysocolla lined vug with large, robust crystals of dark green Clinoatacamite. These are regarded as the world's best Clinoatacamite specimens. The Lily Mine is now closed.

Lot of three fantastic Quartz crystals from France, each with unusual form, exceptional luster, and transparency. They all have faden lines and are of top quality and out of an old collection.

Pyrite and red crystals of Hutchinsonite on matrix. Hutchinsonite is a rare thallium sulfosalt species and these recently found red crystals are some of the best ever found. Crystals reach 8mm long and contrast nicely with the Pyrite. Undamaged with an even distribution of both species across the front face. About as nice a Hutchinsonite specimen as you could expect and the best one I've ever had.

Specimen of solid Chalcocite from the classic Cornwall locality. The Chalcocite grew in a narrow seam and where growth allowed, well formed striated crystals to 2cm formed.

Well crystallized Copper specimen with branches that come together at the top in a mass of very sharp octahedrons of Copper crystals with individuals crystals 7mm wide. Found in 2008 by Bob Barron while metal detecting the lake floor of Lake Superior in about 15 feet of water off Eagle Harbor.
