Barite- perfect rosettes
stock #18.1-434
La Union Mine, Sierra de Cartagena
Murcia, Spain
5.8 x 3.3 x 2.6 CM (cabinet)
price: $380
Late Summer 2018

Remarkable, perfect and esthetic. Free standing rosettes of Barite crystals on a rough matrix arranged in a line. This locale has produced a lot of nice Barite specimens but very few have anything close to this elegant perfection. Under 40X magnification there are no chips or damage seen, which is incredible with such a delicate mineral in thin bladed crystals. Better in person too.
SOLD Kutnohorite
stock #SOLD 18-AX-14-325
Wessels Mine, Hotazel, Northern Kalahari Mn Fields
Northern Areas, South Africa
8.8 x 4.7 x 2.8 CM (cabinet)
price: $0
Late Summer 2018

Great color and fine form, a choice cabinet specimen of sculptural Kutnohorite. The Kalahari Manganese field has produced the very best specimens of this specie and this is a very choice piece with three dimensional form. No damage and nearly pure Kutnohorite there is just a tiny bit of adhering matrix on the back side. Several forms of the mineral are well presented and the whole displays well. Quality color and form like this is almost never available now, this specimen is from finds a few years ago.
Cassiterite -huge for locale, with Ferberite, Arsenopyrite, Chalcopyrite, Quartz, Muscovite, Stannite, Fluorite etc.
stock #18-AX-29-046
Yaogangxian Mine, Yizhang County
Hunan Province, China
4.8 x 4 x 2.8 CM (miniature)
price: $1600
Late Summer 2018

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.
Quartz -optically clear
stock #18.1-425
Penas Blancas, Bourbur
Boyaca, Colombia
4.3 x 2.2 x 1.5 CM (miniature)
price: $80
Late Summer 2018

The clarity and perfection of the top pieces of Penas Blancas (Colombia) Quartz are just amazing. This is a textbook perfect, clean and very lustrous crystal. Hard to fully appreciate in photos, the crystal acts a prism and the striations will diffract light unlike other Quartz. We source at the mine and select a very small percentage of single prisms, offering only the most perfect of each find. The recent finds at Penas represent a great value for price to quality that is rare in the mineral world.
Beryl var Aquamarine on Albite
stock #6.2-170A
Mt. Xuebaoding, Pingwu Co., Mianyang Pref.
Sichuan, China
7.1 x 5.1 x 4.1 CM (cabinet)
price: $330
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.
SOLD Hematite -fine single crystal
stock #SOLD 18-AX-14-384
N'Chwanning II Mine, Kalahari Manganese Filed
Northern Cape Province, South Africa
2.2 x 2.2 x 1.2 CM (thumbnail)
price: $0
Late Summer 2018

Single crystal of Hematite with mirror bright faces. An impressively lustrous thumbnail in fine condition showing textbook quality form. Crystalized all around, a growth contact is at the base but hat too is recrystallized, no chipping or dings anyplace. This find of Hematites ranks as one of the great mineral discoveries of the century (so far).
stock #18-AX-10-036
Hale Crek Mine, Mad River Rock, Trinity County
California, United States
8.1 x 6.9 x 6.4 CM (cabinet)
price: $800
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.
Garnet (Almandine)- Antique specimen
stock #13.1-387
Ziller Valley, North Tyrol
Tyrol, Austria
4.5 x 3.4 x 3 CM (miniature)
price: $140
Late Summer 2018

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.
