Rhodochrosite - scalenohedral crystals
stock #15.1-046
Uchucchacua Mine, Oyon Province
Lima Department, Peru
5.1 x 3.1 x 2.9 CM (small cabinet/large miniature)
price: $340

A cluster of deep red Rhodochrosite crystals up to 1 CM long contrast with the dark matrix. Rich color and very good luster, this piece from late 1990's vintage mining at Uchucchacua. Scalenohedral Rhodos are much less common than rhombohedral habit and just a few worldwide localities have produced these. There are almost always some tip cleaves on these delicate crystals, this one is no exception but not too many and not distracting. This also keeps this affordable even though it looks like it should be much more expensive. A good intense red color and the crystals are translucent to transparent.
Beryl - tabular Aquamarine on Muscovite
stock #6.2-089
Mt. Xuebaoding, Pingwu Co., Mianyang Pref.
Sichuan Province, China
5.3 x 4.7 x 2.1 CM (small cabinet/ large miniature)
price: $300

A well-defined, transparent, textbook-form tabular Aquamarine crystal perched on Muscovite. The crystal is in far better than typical condition it has some minor contacts and spots where re-crystallization patterns are seen on the wide faces. Only one chip that is not very noticeable which is remarkable, overall quite fine. This habit of Beryl is rare world wide, it was however strangely more common in 2000-2012 at Xuebaoding. The locality has not been very productive and most of the mining has moved to areas with different mineralogy. These are becoming modern classics but can sometimes still be found at a good price.
Calcite on Adamite
stock #18-AX-11-280
Mina Ojuela, Mapimi
Durango, Mexico
5 x 4.2 x 2.3 CM (miniature)
price: $165

Sparkling reddish-pink Calcites encrust and contrast with green Adamite balls. Great luster and vivid color, this is hard to fully appreciate in photos but has really good display impact. Most of the Adamite is fully encased under the Calcite but it is seen clearly at some angles. Ojuela has produced many fine Adamites in many habits during a long history. This color combo is not so common, this miniature piece is in fine undamaged condition and would go well in a suite of choice Mexican minerals.
SOLD Alkali Beryl
stock #SOLD 19.1-874
Deo Darrah, Khash / Kuran Wa Munjan Districts
Badakshan, Afghanistan
3.9 x 2.3 x 1.5 CM (miniature)
price: $0

A very choice specimen of intense blue Alkali Beryl from the amazing discovery two years ago. These tabular habit Beryl have a unique stacked structure, are zoned with the middle being a deeper hue. This is in perfect undamaged condition. When these were first found it was thought they were a new specie or were Vorobyevite (another rare Beryl family specie). The final conclusion is these are super rich in Alkalai so classified as an Alkali-Beryl and have distinctive appearance but are not a separate specie. There were not many found and these are now highly prized as esthetic, rare and a major modern discovery. This is an especially choice piece. Looks fine from almost any angle, this is a fine addition to any serious suite of pegmatite minerals, Beryls or an esthetic cabinet, the color is exceptional in person.
Milarite on Valencianite and Quartz
stock #18-AX-10-589
Valenciana Mine (Mina La Valenciana), Municipio de Guanajuato
Guanajuato, Mexico
7.8 x 5.8 x 5.4 CM (cabinet)
price: $160

One of the more uncommon Beryllium Silicate species, Milarite is a real "mineral collectors" specie. This piece is from the find some decades ago in Guanajuato, Mexico. The Matrix is a mix of Quartz and Valencianite (variety of Adularia). The Valencia Mine is the type locality for the Feldspar and was the source of these small bright yellow Milarites which were big news in the mineral world. This piece has several very small crystal and one a bit larger (about 8mm). These are flat habit and the structure is not as evident without good magnification. A fair example of the find that is not crazy expensive.
Elbaite - gem-clear Indicolite
stock #20.1-294
Barra do Salinas Mining District, Coronel Murta
Minas Gerais, Brazil
2.6 x .7 x .5 CM (thumbnail)
price: $150

Deep blue transparent Indicolite crystal with a contrasting termination. An older specimen (1960's) this has a subtle zoning but is mostly a consistent blue color. In choice condition, this is an attractive thumbnail with complete termination and glassy luster.
Pink Fluorite, Epidote, Adularia, Chlorite, Quartz etc.
stock #AX-10-864
Val Cristallina (Cristallina Valley)
Grischun (Grisons), Switzerland
15.7 x 9.3 x 4.9 CM (cabinet /museum)
price: $520

A large, colorful Swiss alpine specimen featuring several well-crystallized species in scattered clusters. The centerpiece is the pink octahedral Fluorites many of which are gem clear. In addition, there are a few small colorless Fluorites and a few areas of dark nearly black Fluorite which is coated by and included with Chlorite. The specimen is also multi-colored fluorescent and amazing when examined under good magnification. Gem clear Quartz crystals show typical alpine habits and sharp transparent Epidote and Adularia crystals add contrast. Very pretty in person this looks even better as you look closer.
Chalcocite pseudo after Covellite - Classic USA
stock #13.1-375
Leonard Mine, Butte, Silver Bow County
Montana, United States
3.4 x 3.3 x 2.2 CM (small miniature/ large thumbnail (toenail))
price: $2400

Fantastic form and a killer pseudomorph. This vintage Butte specimen shows perfectly the form of the original Covellite crystals which are almost fully replaced by Chalcocite. It looks like a tiny bit of Covellite may remain on the backside, but if so it is minor. This is an early specimen with excellent provenance, a tattered Roy Hopping (NYC Mineral dealer vintage 1898) label is included. This was also in the collection of Louis Zara (famed NYC collector, author and publisher of the Mineral Digest. His label is also included. The specimen is in exceptional condition, fully undamaged and attractive from almost any angle. Well-crystallized Covellite is remarkably rare worldwide with only two significant localities, both long closed. It is even less common to see a well-defined pseudomorph with sharp crystals like this.
