Prehnite crystals -Vintage Swiss
Muotta Naira, Piz Lai BlauNalps Valley, Tujetsch, Vorderrhein
11.3 x 6.4 x 2.6 CM (cabinet)
A matrix plate with clear light green Prehnite crystals to 1.4 CM scattered with smaller Prehnites and some tiny Epidote and Byssolite. Classic specimen, ex Charles Noll collection and a much older label from an unknown collection. In fine condition overall, the main crystals are pristine. Some crystals are also on the underside but the view shown is the logical display face.
Incredible form on this Indian specimen. A radiating burst of amethysts is the base for perfect scepters that are very slender, twisted and have lepidocrocite needles inside some tips with a red color. In pristine condition, no damage seen even with 10x magnification. from the amazing finds at Karur in Tamil Nadu, this level of perfection and esthetics is very very rare. Better in person this piece was selected from many hundreds of good pieces as on a quality level of its own.
Barite -window pane type
Cerro Warihuyn - Miraflores, Huamalies Prov.
7.8 x 4.7 x 4.5 CM (cabinet)
Transparent, sharp and lustrous Barites in rosette form on minimal matrix. Undamaged and with a light smoky color this has several excellent display angles with good impact. The digging at Cerro Warihuynan has been a major discovery of fine Barites. Even in the flood of good specimens, this piece is far better than typical, a very choice example with a price to quality value ratio that is hard to find these days.
Resuperferolitica Mine, Santa Eufemia
8 x 6 cm (cabinet)
Ex. John Marshall collection, a very well crystallized Santa Eufemia Pyro with large individual crystals that exceed 1.6 CM. This is overall in excellent condition and is crystallized on 2 sides with large vugs filled with sprays and freestanding individual crystals. A super display piece from a very important locality.
A cabinet sized specimen well crystalized on front and back with fine Cerussite. These crystals are green (likely caused by copper or Chrysocolla inclusions) and yellow (often called Chromian Cerussite). This is from a series of pockets found at the famed Daoping mine near Yangshao in 2004-5. Overall in fine condition, no damage seen by naked eye but a few micro dings can be seen with 10X magnification, and that only on outer edges. Since Cerussite is so delicate this peice is amazingly pristine. This sort of Cerussite has not been found for a few years, and now is being recognized as a significant find. There has been discussion (argument) as to weather or not to label these are Chromian Cerussites or Cuprian or nothing at all. It seems there have been differing results in analysis. As we await resolution we simply call this Cerussite.
A completely transparent cluster of Garnets that has no matrix and yet also has good isolation of the largest crystals. A relatively three dimensional specimen that has an unusual "etched" or melted look to several crystals. With strong magnification this is seen as complex modifications to edges and very fine striations that are not typical. An attractive and (in my experience) rare oddity that is also affordable. Internal clarity is near 100 clean facet grade gem.
A big, complete Garnet crystal with honey brown color from an uncommon locality, Zulova in the Moravian area of Czech Republic. This is quite exceptional for this old locale and the condition, size and quality are top. Some surface alterations are seen on faces with a deeper red color beneath. Matt luster overall but some faces have a glassy surface as well. All examples I know from this location are much smaller, darker and usually have considerable damage or wear. One old label is included.
Fluorite -Classic New York cube
Penfiled Quarry, Penfield, Monroe County
3.2 x 2.2 x 3 CM (small miniature/ large thumbnail (toenail))
Sharp purple-blue cube of Penfield NY. Fluorite, with both glass clear and lightly frosted faces. A much sought after locality, these few Fluorites are highly prized. Totally transparent and in far above typical condition, this had been in the Francesco Spertini collection since the sixties. With magnification some interesting growth structures can be seen on faces and inside the cube. The display side is clean and damage free but the underside has a cleave and matrix contact. That underside can be seen through the clear crystal but is easily hidden as it is the obvious base or bottom of the crystal. A good value, these are typical very costly when available.
