A historic specimen from Sala in Sweden the type locality of Salite, which is a discontinued name for Fe rich Diopside. This was a Lechner collection piece (Austria) which was later sold by the Schortmanns's dealership. The Schortmann label dates this to the 1940's though the specimen is probably over 100 years old. The main crystal here is distinct, terminated and is a translucent oil-green color. Some scattered Chalcopyrite adds a contrasting gold. The Diopside is exposed partly but also is well-enclosed by the matrix which is mostly more Diopside. Simply never seen on the market this is a nicely crystallized bit of mineral history.
Cobaltite -classic locale

Worldwide mix summer
An excellent sharp Swedish Cobaltite crystal on typical matrix block of mixed Sulfides (Chalcopyrite etc). The Cobaltite is a modified cube (8MM) with distinct striations and fine metallic luster that is mirror bright as seen. Looks fine by eye, but the cube has a corner contact at one edge seen with magnification and there is a small crack in the crystal not visible without 10x magnification. That said this is far better than average and as near to perfect as we have seen. These are not common and in this quality very rare, often quite pricy.

A sharp 9 MM metallic silver crystal with clear edge modifications perched in matrix. An older specimen from this classic location that has produced perhaps the best ever crystals for the specie. Some minor sulfide overgrowths are seen and the crystal has retained the bright luster that makes these so distinctive. Could easily be trimmed to make a thumbnail if desired. A good example well crystallized for this often damaged specie that is also affordable.
Very fine, sharp bi-colored Stilbites from the Malmberget Mine that is world famed for a great find of gemmy Calcite. This is a rather old specimen with a few very small near colorless Fluorites and associated minerals. The Stilbites are quite sharply terminated reaching over 2 CM long and with bright luster. In excellent condition, no visible damage.

A sizable old location piece with a Dr. Krantz in Bonn label (a little different than most Krantz labels we have seen) there are several sharp octaherdral crystals etched from a calcite matrix. This is not a highly esthetic piece but it is a classic vintage and it does show the blue to purple octahedrons well.
