Fluorite on Quartz
stock #18-AX-20-230
La Viesca Mine, Huergo, La Collada, Siero
Asturias, Spain
6.6 x 4.1 x 3.8 CM (cabinet)
price: $260
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.
Chrysocolla (Druzy overgrowth of Quartz)
stock #18.1-432
Inca De Oro, Chanaral
Atacama Region, Chile
2.7 x 2.5 x 1.6 CM (thumbnail)
price: $110
Late Summer 2018

Bright sparkling blue Chrysocolla thumbnail with very pretty form. Druzy Chrysocolla is found sporadically in small amounts at just a handful of locations worldwide, and the electric color has made it highly desirable for lapidary as well as an esthetic, collectable mineral. The matrix of this piece is a solid dark gossan that has a scalloped surface. The Chrysocolla in this case is likely a pseudomorph of earlier Malachite crystals. Displays well with more impact that usual for the size.
Descloizite -unusual form, iridescent
stock #18.AX-12-055
Berg Aukus, Grootfontein District
Otjozondjupa Region, Namibia
5.5 x 4.3 x 2.6 CM (small cabinet/ large miniature)
price: $190
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".
Chrysocolla - drusy Quartz overgrowths
stock #18.1-433
Inca De Oro, Chanaral
Atacama Region, Chile
4 x 2.6 x 1.7 CM (miniature)
price: $280
Late Summer 2018

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.
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.
