Satiny, transluscent knob of blue Smithsonite. The color is superb!!! It's essentially all solid Smithsonite, contacted on the back and bottom, with just a tiny bit of matrix that the Smithsonite grew around. Out of an old collection.

Pyrrhotite crystal groups with spinel-twin Galena, Quartz, and Chalcopyrite. Highly aesthetic example of Pyrhottite from this locality that has produced many. Damage to the top of the back crystal, otherwise undamaged and good from all angles.

Tall single crystal with good transparency. The bottom end is naturally etched, the top has some flat termination faces and one area of contact. These are no longer being found and transparent crystals of this size are uncommon. .

Elongated Pyrite groups that have replaced a previous mineral, possibly Calcite, on a matrix covered by Sphalerite. The base of one of the Pyrite crystal groups is visible and whatever was there before is all gone now - nothing but solid Pyrite. Bright, shiny luster and undamaged.

Hemispheres of blue Azurite to 1.1cm on matrix with tiny spheres of Malachite. The quality and color of the Azurite on this specimen is the best I've seen from Morenci. Undamaged.

Lustrous 1.2cm Chondrodite crystal in white marble. This is both large sized and very well formed. Most are not so uniform in shape nor do they have such well defined, flat crystal faces. Very gemmy also, with one small nick other wise undamaged. A good one.

Schist and Natrolite hosting a superb 2.8cm Neptunite crystal and about 6 Joaquinite crystals. There is also a partial crystal of Benitoite along the lower edge.

Single octahedron with trigonal surface growth features and some step growth along some edges. Gemmy, with inclusions that give it an overall grey color in normal lighting. Undamaged, weighs 5.44 carats.

Wafer-like crystals of Calcite, Chalcopyrite crystals with an irridesent blue/black surface coating, Quartz and Pyrite. Not uncommon minerals but an uncommonly pretty, balanced specimen.
