Clinochlore is not often seen as a display quality specie, it is usually a minor associate or coating of other minerals. Here the Clinochlore crystals are sizable, well defined and lustrous. The prismatic and sheaf-like crystals are unlike the more normal flat micacous forms. The dark green crystals contrast well with the transparent to translucent white Adularia. Some micro species are noted in spaces between large crystals, most noticable are gemmy Xenotime-Y with a yellow to orange color. A few spots of bright red Rutile crystals are also seen with magnification. Ex. Eric Asselborn Collection (France) this is a superb older Alpine specimen and exceptional for the specie, locality and habit.
Pyrite with Dolomite
Niccioleta Mine, Massa Maratima, Grosseto Province
9.6 x 9.5 x 4.2 CM (cabinet)
A fine and well-developed cluster of Pyrite crystals showing deep striations and bright luster. Ex John Marshall collection, this is a vintage piece from a locality we rarely see, but which was famed for fine Pyrite crystals and some other Sulphides (Stibnite etc). In excellent condition the Pyrites are in clusters and also in well-isolated crystals. This is a solid and stable piece there is no sign of any degeneration or oxidation.
Halite and Tolbachite
Polkowice-Sieroszowice Mine, Glogow County
Lower Silesian Voivodeship,
6.9 x 4.8 x 3.8 CM (cabinet)
Incredible, perfect hoppered cubic crystals of Halite are stacked in an eptaxial cluster. From the recent finds at Polkowice (Poland) this a a textbook example of this form. The crystals have a distinct green color and by analysis this is due to the very rare mineral Tolbachite which is a Copper Chloride not often seen in collections. I consider the better examples of these to be super esthetic and this specimen is excellent by any standard.
A small cabinet of bright drusy Pyromorphite from the famed Wheatley mine (Pennsylvania, USA). The matrix is typical for the mine, the crystals have the dark olive green color that is distinctive to the locale. This specimen is from the collection of WG Levison but unfortunately does not retain any of his labels. This dates to the 1890 era in the collection but the specimen is likely much older, as the mine had closed in the 1860's. The the crystal coverage is quite rich even though the individual crystals are small. With magnification most of these are seen as transparent, sharp and very lustrous.
A large crystalline mass of Galena is host to several cavities filled with brassy Millerite needles. A fine old German specimen from the Pfaffenberg Mine which is best known as a classic source of Galena, and rarely of Millerite. A druse of Quartz adds some contrast and sparkle as well, but the real attraction is the nests of radiating Millerites on several faces of the matrix. This mine was operated for Iron and was a major operation by the mid 1800's, though mining in the zone can be traced as far back as 1400. This was operated until 1962, the Millerites from here are uncommon on the market and are German classics.
From a relatively new find (2020-21) by Denis Beals; these are larger rose Garnets from an area of the Sierra de las Cruces. This site has produced a few relatively large Garnets embedded in a hard Rhyolite matrix. Noticeably different in habit and look from the previous finds in this region, this piece is an excellent example. A cluster of two main intergrown Grossular crystals show good luster and contrast well with the matrix. Some contacting is noted, there are geometric imprints of other Garnets and some rougher faces, as was true of every piece we examined from the find. Nevertheless, while this is not a piece for perfectionists it is still a fine and colorful Mexican Garnet unlike anything else from the region.
Very large and welL-defined cluster of Sturmanite crystals with a patina that in some light shows a iridescent color play. Not long ago Sturmanite was a very rare mineral and such huge crystals were unheard of. The great finds from South Africa changed that, but this size and level of quality is still very uncommon. Very impressive in person and now very hard to get.
A striking fine Tourmaline specimen with both fine color and nice matrix contrast. The largest multicolored Elbaite is 4.5 CM long and well-isolated, free standing. All are gemmy and have glassy lustrous faces. There are several smaller crystals scattered on the matrix including a few damaged crystals some of which are partly recrystallized. The major crystals are in fine shape and are the classic gemmy Paprock type with vivid pastel coloring. The largest crystals have flat basal termination but some others are the prismatic type. The color mix of the purple and off white matrix contrasts well with the glassy pink and green Tourmaline.
