A half nodule from the famed Variscite locality of Clay Canyon. This is quite an unusual nodule, it has complex zoned "eyes" showing these three Phosphates in concentric circles. An impressive illustration of the sequential deposition and alteration of these minerals, the details are especially striking. With good magnification it can be seen that there are small open cavities between some of the rings which contain micro crystals of other unidentified species. An early piece from the classic finds by Ed Over and Arthur Montgomery. In excellent condition, the color is a little brighter in person, overall a choice and mineralogically interesting piece of a type I have never seen before.
A complete and perfect elongated crystal of Pyrrhotite is perched on a complex crystalized matrix. The Pyrrhotite looks very much like two crystals side by side but is in fact a single crystal. Fine stepped growths and silky patina on all sides of the specimen. The Galena and Sphalerite are both very lustrous and the whole piece is damage-free. An older specimen from Dalnegorsk, this is vintage about 1996.
A very esthetic and unusual specimen from the remarkable finds at the Rudna Mine. A radiating spray of sharp, transparent bladed crystals of Gypsum are on a green matrix that has been determined to be in part Paratacamite. In excellent condition, many of the blades show fishtail terminations indicating that most are twinned. A fine example from recent discoveries, this can be shipped but we can also deliver to any of the major mineral shows that we attend.
Apatite on Albite with Clinochlore
Tormiq Valley, Haramoush Mountains, Skardu District
5 x 4.1 x 4.4 CM (small cabinet/ large miniature)
Compound crystal of Apatite CaF 4.7 CM across is perched nicely on a snowy white Albite matrix sprinkled with Clinochlore. Well-defined faces, good luster and with nice striations, the crystal is a cream-yellow color and transparent in parts. Good fluorescence also. An alpine style habit and association, this from Pakistan though, it really looks like a fine Austrian piece. Older labels included, Ex Nick Carruth (Cornwall, UK) David Crawford and Charles Noll (USA). In very good condition no obvious damage and better in person too.
Microcline var. Amazonite
Lake George area, Teller County
7.3 x 4.6 5 CM (cabinet)
Pale-green blocky crystals of Amazonite in a classic cluster from Colorado. The main crystals are complete and perfect condition, the outer edges are broken as is typical when removed from a shattered pocket. An affordable specimen from this famed region, attractive on all sides.
