Grouping of Copper crystals with a rich red patina. Ex. Peter Bancroft specimen.

Bright blue, spherical crystal groups of Azurite atop rolling hills of satiny Malachite. A large, flat specimen that would add a huge amount of color to any display. Undamaged, historic specimen out of an old collection built in the 1960s and 1970s.

Interconnected spherical clusters of Azurite with minor amounts of attached Malchite. This is a superb Greek Azurite specimen and was photographed in Lapis magazine. It is a floater specimen well crystallized all around and has one repair. Extraordinary color!

Large, chunky Hematite crystal with an uncommon psuedocubic form. Great luster with parallel surface striations. This is an old specimen from a collection dating back to the 60s and 70s. It came without precise locality information, but I suspect it is from the Casa de Pedra mine in Congonhas, Minas Gerais. It's complete all around with some indentations from other crystals on top near the back, but remarkably pristine with only a couple small nicks. Even the bottom is rehealed. Weighs 2 pounds and 14 ounces!

Classic Tsumeb specimen of Dioptase on white Calcite. Super lustrous, transluscent Dioptase crystals in small clusters and isolated crystals. There is damage to a couple crystals, but the vast majority are fine and undamaged. Despite the damage, this quality is rare to find now.

Deep purple blue Tanzanite crystal perched atop a matrix of Tanzanite, Calcite, and Graphite. The Tanzanite is translucent with a jagged termination, and is undamaged. A fine, showy matrix Tanzanite that won't break the bank.
