Killer Tanzanite thumbnail that's also a great association piece.  Fine, gemmy blue Tanzanite crystal with excellent luster and great transparency with attached distinct, individual Prehnite crystals (analyzed) on the backside. Prehnite from Merelani is usually seen as rounded aggregates, yet on this specimen they occur as individual crystals to 7mm wide. In addition to the Prehnite, there are white crystals of an unidentified mineral also attached to the backside. A very nice Tanzanite, undamaged with TOP luster, good color and highly gemmy.

Single, stout hexagonal prism of Hematite, an uncommon crystal form for Hematite that reminds me of a style rarely seen in Kalahari Hematite crytals. Doubly-terminated crystal silvery in color with bright metallic luster. Complete and undamaged with uniform shape though with with a bit of cavernous growth on one termination and some indents from other crystals on some prism faces. These are found in an iron mine on an island located 8 kilometers off the coast of Iran.

Cluster of octahedral Cuprite crystals with associated bright yellow Miersite (which is a member of the chlorargyrite group of minerals). Only a small number of the recovered Cuprite specimens were associated with Miersite. Complete, undamaged floater specimen with no points of contact.

Vitreous brown Bementite, a rare hydrous manganese silicate, intergrown with Calcite over a black rock matrix. Franklin is the Type locality for Bementite, named after USA collector Clarence Bement. A rich example that comes with an old Minerals Unlimited label.

Fine thumbnail with a 1.4cm Carrollite crystal perched atop smaller Carrollite and chalcopyrite crystals. A stunner of a thumbnail with bright metallic luster.

Rich specimen of red Sarabauite in matrix. Sarabauite is a rare antimony contining mineral. The Sarabau Mine, located on the island of Borneo, is the Type locality for the species.

Floater cluster of twinned Titanite crystals intergrown with Ferro Actinolite. Olive green to yellowish brown in color with gem areas. Nice form, well crystallized all around.

Aesthetic, curved wire-like specimen of Silver. The Silver is an elongated spinel-twinned crystal with smaller attached side crystals.

Superb Rose Quartz crystal formation atop a single white Quartz crystal. A highly showy example.

Lustrous metallic black Hematite crystals on elongated black crystals of the rare mineral Gaudefroyite. Minor amounts of red Andradite add color.

Large, transparent Quartz crystal with attached and partially included black Helvite crystals. The Quartz has chlorite inclusions and has a well defined green phantom right near the termination. It also has a slight reddish cast in areas. As a bonus, the base of the crystal is completely rehealed.

Transparent, colorless Phenakite crystals with tan Orthoclase and Muscovite on matrix. The Phenakite crystals are really good and reach 6mm in size. There are 4 good crystals in the main display area and a 5th crystal on the side.

Translucent red/orange color pagoda-shaped crystal of Wurtzite. At the tips are dark areas of epitaxial Sphalerite. These recent Wurtzite specimens from the Merelani Tanzanite mines are the world's best and now rarely found.

Single, stout hexagonal prism of Hematite, an uncommon crystal form for Hematite that reminds me of a style rarely seen in Kalahari Hematite crytals. Doubly-terminated crystal silvery in color with bright metallic luster. Complete and undamaged with uniform shape though with a contact on one part of the bottom termination where it grew against other crystals. There are also smaller side crystals attached. These are found in an iron mine on an island located 8 kilometers off the coast of Iran.
