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.
SOLD Topaz- Imperial type, red-orange
stock #SOLD 17.1-193
Antonio Pereira Mine, Ouro Preto
Minas Gerais, Brazil
4.7 x 1.3 x .7 CM (miniature)
price: $0
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.
Adamite with Calcite
stock #17.1-617
Mina Ojuela, Mapimi
Durango, Mexico
4.9 x 3.8 x 3.8 CM (miniature)
price: $125
Worldwide mix summer

Bright lemon yellow crystals that are sharp and gemmy contrast with white Calcites. Choice and lustrous, this is an older specimen from the "golden era" at Mina Ojuela. Vivid Fluorescence and in great condition.
Benstonite on Fluorite
stock #15.1-967-SM-3121
Cave-in-Rock, Hardin County
Illinois, United States
6.7 x 5.7 x 4.6 CM (cabinet)
price: $450
Worldwide mix summer

Benstonite in unusual distinct crystals clustered on Fluorite cubes. Ex Charles Noll collection, a choice example of this uncommon mineral that has always been a very desirable rarity from this region. The Fluorite cubes are also very sharp and clean with strong Fluorescence. These are only available from older collections and most are just a whitish coating on other minerals. This almost certainly came from the Minerva mine but the label does not give that specific detail so we leave this listed as Cave-in Rock only.
Malachite - Primary crystals, classic locale
stock #15.1-1064-SM2923
Andrassy II. Mine, Rudabanya, Rudabanyai Mts.
Borosod-Abauj-Zemplen Co., Hungary
7.6 x 5.2 x 3.2 CM (cabinet)
price: $750
Worldwide mix summer

An old, well formed and crystallized Malachite from Rudebanya ex Charles Noll collection. The Malachite is quite lustrous and contrasts with the gossan matrix, but this is nearly all Malachite. This is also a well formed and fine Primary Malachite, not a pseudomorph. The luster is bright and satin like with clustered groups of prismatic crystals in spherical arrangements. In excellent condition, we do not know the vintage of this piece but the style is only seen in very old collections, and the locality has been mined since the copper age, it is one of the oldest mineral sites in Europe. Impossible to find specimens of this caliber today.
