Fluorite on Quartz
La Viesca Mine, Huergo, La Collada, Siero
6.6 x 4.1 x 3.8 CM (cabinet)
Late Summer 2018
A multi-color phantom Fluorite nicely perched on a sculptural matrix covered with druzy Quartz crystals. Excellent transparency and in fine condition, there are a few additional Fluorites on the specimen one of which is a slender, highly elongated cube. A classic European locale, the La Viesca Mine is famed for vibrant color varieties and general quality of its Fluorites. This one is a bit unusual but still has the look and style well known from this venerable locality.
Descloizite -unusual form, iridescent
Berg Aukus, Grootfontein District
5.5 x 4.3 x 2.6 CM (small cabinet/ large miniature)
Late Summer 2018
There are many different habits seen in the Descoizites of Berg Aukus, which is certainly the premier locale for this mineral. This specimen has a rounded series of crystal aggregates that present curved faces and a colorful patina. The iridescence is most striking and at first glance this looks like a fine Chalcocite. Undamaged, pristine condition, and crystalized all around, the underside is a hollow cup holding more traditional forms of small bright red Descloizite crystals. We have handled and seen many fine Berg Aukus specimens but this piece is unique in my experience. Ex William Hladysz collection, his catalog notes "very rare habit, unlike any other".
Super bright color and sparkling luster, this has a tiny bit of Malachite remaining but most all is pure Chrysocolla. The Chrysocolla shows the elongated forms of primary Malachite crystals which it has replaced. The brilliant blue fingers on this piece are radiating outward from a Gossan matrix and are fully encased with clear, sparkling Quartz. Fine and delicate, in excellent condition and with strong display impact.
The very best Yaogangxian Cassiterite I have ever seen, with the largest crystals as well. An excellent multi-specie piece mostly composed of superb Cassiterite. This locale has produced thousands of excellent mineral specimens but Cassiterite is very rare from this famed locale. Sharp lustrous crystals to almost 3 CM are arranged in a radiating cluster on a very complex matrix. I count at least 7 mineral species on this miniature, but the Cassiterite is clearly dominant and is in fine condition as well. A superb modern classic and a very important Yaoganxian specimen.
Beryl var Aquamarine on Albite
Mt. Xuebaoding, Pingwu Co., Mianyang Pref.
7.1 x 5.1 x 4.1 CM (cabinet)
Late Summer 2018
An esthetic and sharp edged piece. The Aquas are super clear, mid-range blue, (largest is 4.2 CM across,) tabular crystals consisting of two pinicoids and no prism faces. This is a less common form for Aqua at Pingwu (and very rare worldwide) normally there are prism faces present. The albite is well crystalized and some is quite gemmy too. The piece has a saw marks on base and side (from the collecting) not visible on display side. Displays very well as seen, but is better in person. There are some contacts and tiny edge chipping present that is not distracting yet keeps this from being a far more expensive specimen.
Hale Crek Mine, Mad River Rock, Trinity County
8.1 x 6.9 x 6.4 CM (cabinet)
Late Summer 2018
Superb old USA (California) Inesite with large and very fine crystals lining an open pocket. Hale Creek Inesites could still be collected about 45-50 years ago, but not recently, they are a US classic, rarely available in this quality. This specimen is in fine condition, with prismatic crystals up to 1.7 CM but most are about 1.2 CM (which is huge for the locale and specie). Displays well from several angles, the open vug shows several differing habits and radiating clusters. Ex William Hladysz and Ara Dildillian collections, this is by far the best California Inesite I have seen for sale in 20 years.
A very old (18th century) Tyrolian Garnet specimen from the Zillertal. This area has been the source of Almandine for centuries, these were sold and traded worldwide. This comes with an early Julias Bohm label and a much older (crumbling) one as well as an affixed one on the specimen back. The matrix is an unusual one, a complex mix with Actinolite, Hematite, Magnetite, Quartz and more unusual, small Galena and other Sulfides. Not the usual mica Schists we typically see from the Tyrol. The main crystal is well exposed and complete 1.5 CM in diameter and has some good translucent areas.
A long (2.7 CM) terminated twin Cinnabar on a crystallized Dolomite vug. A strong piece with esthetic structure, the back has been sawn to aid collecting this piece, the saw marks are not visible on display. With strong light the crystal is quite translucent and glows a deep cherry red. The termination shows the complex re-entrant angles (drill bit type) of twinning. There is a crack near the base of the crystal that looks like an old repair, checking with Acetone did not reveal any problem but we have priced this as if it was repaired (a previous price of 1100.00 was a very good value if not repaired). The better Chinese Cinnabar crystals are well known as the worlds best and were eagerly sought for more than 150 years. For a while in the past two decades these were more available but now the old mines are closed. We will hope that the future produces more.
