Sharp yellow crystals in clusters on contrasting fingers of Gossan matrix. Ex Marty Zinn collection, a very three dimensional specimen with glassy prisms standing on end above the reddish matrix. several fan aggregates are present as well as isolated single crystals with transparent tips. In excellent undamaged condition.
A large, somewhat crude red Cuprite octahedron (3.5 CM) with some unusual growth features and complex faces sets nicely on Malachite matrix. Two of the faces have odd holes (one circular, one triangular) and several parts of the crystal show stepped regrowths. Great color contrast, with backlighting the Cuprite glows a brilliant cherry red. We have not backlit the specimen as that can be misleading, but the cuprite is fully translucent and seems to be facet grade clear red inside. Ex John Marshall collection (his label and card are included) acquired in 1990 from G. Gauthier.
Very well formed, large (to 4 CM across) rosettes of sharp and lustrous Semseyite in undamaged condition. The matrix is a mix of lustrous black Sphalerites and Sphaerosiderite balls colored by Boulangerite. A few Chalcopyrites sprinkled in add a little extra color. These are the biggest undamaged osettes we have handled, the overall esthetics is very strong and fine for the specie.
A superb large euhedral crystal (7.8 CM tall) dominates a cluster of smaller crystals. Sharp, complete all around and undamaged, this is an incredible example from the famous Linopolis find thirty years ago. Micro crystals of some unidentified Phosphates are also scattered on the specimen and add a little sparkle. Ex Charles Noll collection, the original label call this Herderite as these wwere known then, now understood to be Hydroxlherderite. Most faces show a glassy luster and are transparent in parts. The color of Hydroxylherderite from here can vary widely, this one is mostly light violet-purple but with some zones of greenish, grey and orange. Display well from all sides and the main crystal is textbook quality. These only appear now from old collections like this.
Sharp Fluorites from the classic Malmberget locality, famed for butterfly twin Calcites. Less famed but still excellent are the Fluorites and Stilbites from here. An excellent example in very good condition as seen with several mint green octahedral crystals. The main Quartz is about 2 CM tall and well decorated by bright Chalcopyrites, adding a nice contrast and luster. No damage seen by naked eye, some tiny chips can be found with 20X magnification, so very close but not quite perfect. A modern classic locale, these FLUORITES ARE NOT OFTEN AVAILABLE
Silver with Calcite
Batopilas, Andres del Rio District
4 x 3.1 x 2.1 CM (miniature)
A very delicate cluster of wires, herringbone crystals and tiny spinel twins of native Silver. From the now classic locale of Batopilas, this has several small bits of adhering Calcite much like ornaments on tree branches. Due to the fragility of this piece it is best to make a by hand delivery or we will ship in soap powder, insured. Ex Larry White collection.
Grossular (pink) w. Diopside
Jeffrey Mine, Asbestos
4.9 x 2.5 x 1.5 CM (miniature)
One of the rarest colors of Grossular from Jeffrey is pink, and especially desirable is on a contrasting green Diopside. Far above average size for the main crystal at 1.2 CM and gemmy. Sharp edges and bright luster make this especially attractive. There are some contacts and chips mostly on smaller crystals but these are not easily seen. This also keeps the cost far below the usual level for a Jeffrey pink. This could be trimmed to a very fine thumbnail if desired.
A sizable Chiastolite crystal with a distinct Fairy cross from an uncommon locale, Rwanda. One face has been ground to show the structure with the back and sides left fully natural. This is the only example I have ever seen from there, this is from a 1970s vintage collection.
