Massive Ajo Copper with a row of tall crystals to 13cm. This formed in a thin seam and has a uniform thickness throughout the specimen. 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.

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.

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 both good crystals and alot of character, looking somewhat like a 'walking copper'. Good sharp crystals and good patina.

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.
