Silver -branching crystals and wires
stock #18.1-271
Port Radium, Great Bear Lake, Mackenzie Disrtict
Northwest Territories, Canada
2.1 x 2 x .2 CM (thumbnail)
price: $125
Worldwide mix summer

A delicate Silver specimen with branching feathery crystals and no matrix at all. From the Larry White Thumbnail collection, this has a few bright metallic areas and lots of nice dark patina. The last mine in the area closed down in 1982, the area is now reclaimed and abandoned, so this specimen is certainly older than that. In fine condition, the habit is similar to some Batopilas specimens, but the structure is a bit more hefty.
Krohnkite - large crystals, rare habit
stock #A18.1-AX- 18-037
Chuquicamata Mine, Calama, El Loa Province
Antofagasta Region, Chile
4.7 x 3.6 x 3.4 CM (miniature)
price: $580
Worldwide mix summer

Bright, large blocky habit Krohnkite crystals in a cluster with minimal matrix. From the type locale, Chuquicamata which is the only place where this rare Copper Halide was ever found in such fine crystals. While and non micro crystals are rare most of those are fibrous growths or slender clusters. Prismatic habits like this are far more uncommon, and were all found long ago. Most of the existing specimens were collected long before 1934 (the early 1900 era was most productive) but it is probable a few came out later. The zone where these were found was long ago disappeared, consumed by the largest open pit mine on the planet. Only seen now from old collections.
Langite
stock #16.1-1282
Spania Dolina, Banska Bystrica County
Banska Bystrica Region, Slovakia
12.2 x 9.1 x 5.3 CM (cabinet)
price: $360
Worldwide mix summer

Incredibly rich, a large old Langite specimen with a fine blue-green color that is quite intense. This secondary copper Sulphate specie is a dimorph of Wroewolfeite and can be confused with it or Posnackite. While Langite is found as micros at many localities, the best and largest specimens are mostly from old Slovakian mines. The matrix here has at least some Langite on every side, but the 3 main faces have the best coverage and most distinct crystals. This could easily be made in to several very good specimens but we like the large size for impact. Formerly in the Vrzal collection in Brno, Czech Republic.
Smithsonite - muti colored multi layered
stock #17.1-607
Choix, Municipio de Choix
Sinola, Mexico
6.8 x 5.6 x 2.6 CM (cabinet)
price: $260
Worldwide mix summer

A choice small cabinet Smithsonite made of purple and pink botryoidal layers over a green core. There is minimal matrix. From the now defunct Choix locale, this has a fine color and luster that is much better in person. In undamaged condition, these Smithsonites are no longer being found. A modern classic locale, better specimens like this really do stand out and are a good value.
Topaz- Imperial type, red-orange
stock #17.1-193
Antonio Pereira Mine, Ouro Preto
Minas Gerais, Brazil
4.7 x 1.3 x .7 CM (miniature)
price: $1750
Worldwide mix summer

A very clean, gem clear Topaz with a strong pink- red color in the core with the more orange zones on the edges. The rarest and most valued colors of Imperial Topaz are the red and purple hues. This is an especially choice clear single prism with glasslike faces, no damage or cleaves. The color is stronger and a bit deeper in person, the bulk of this is of facet grade. Mined in 2016 from the Pereira Mine in Ouro Preto, well known as the sole locale for the true "imperial" Topaz.
Kermesite - red crystals with Valentinite
stock #AX-27-211
Pezinok
Bratislava region, Slovakia
6.3 x 4. 7 x 2.9 CM (cabinet)
price: $320
Worldwide mix summer

Dense, rich red coverage of needles in clusters, radiating sprays and clumps. There are small Stibnites and a druse of Valentinite crystals behind the Kermesites. Unusually bright red color and in fine condition. Ex Terry Szenics collection, this presents super well under magnification with very impressive crystal structures seen. These older Slovakian Kermesites are very different from the later Chinese specimens, and the color is far brighter red.
SOLD Pyromorphite
stock #SOLD 15.1-980-SM 1456
Horcajo, Ciudad Real
Castile-La Mancha, Spain
4.6 x 3.7 x 3.8 CM (miniature)
price: $0
Worldwide mix summer

A first rate Horcajo Pyromorphite with fine color and in impeccable condition. Crystals in several habits including simple needles and barrel crystals with hoppers and pointed tip terminations. Individual prisms to 1.2 CM are thickly strewn on matrix, but despite the delicacy the condition is remarkable. Ex Charles Noll collection obtained by him over 40 years ago.
Fluorite - distinct phantoms
stock #16.1-739
Aouli. Midelt, Khenifra Province
Meknes-Tafilalet Region, Morocco
5 x 4.2 x 2.9 CM (small cabinet/large miniature)
price: $330
Worldwide mix summer

Impressive and clear, these are very sharp purple phantoms inside bright yellow Fluorite cubes. We have seen hundreds of Aouli Fluorites but never this quality of phantom. Overall sharp and displays well but not a piece for perfectionists, there are small nicks and cleaves. Despite that there is strong impact for color, form and the distinct phantoms stand out well.
