Fluorite with Chalcopyrite, Quartz
stock #16.1-327
Heights Mine, Durham, Weardale County
Durham, England
9.2 x 6.2 x 4.8 CM (cabinet)
price: $390


A classic, well formed English Fluorite that has a prominent, isolated main crystal that is dominant on this specimen. Chalcopyrite and small Quartz crystals are scattered on the display surface. Strong deep color, in fine condition and vividly fluorescent, ex Hitchings collection. This is a pre 1970 specimen and possibly much older, a classic Weardale piece that displays well.
Albite (v. Cleavelandite) - very fine crystals
stock #19.1-283-(3856)
Virgem do Lapa
Minas Gerais, Brazil
7 x 5.8 x 2.7 CM (cabinet)
price: $750


Large, perfect gem clear crystals of Albite with fine textbook form. Ex Rock Currier collection (label # 3856) this shows well the quality of esthetics that Rock was well known for. It is surprising how few collections or even Pegmatite suites we see have a good example of this common Feldspar. These are almost never so esthetic as seen here, this is a striking piece. Albite/ Cleavlandite is a common mineral, but crystals of this size and perfection are just very rare. These crystals are formed as thin hexagonal plates with beveled edges and transverse striations. The whole group is stacked as an epitaxial cluster and shows brilliant glasslike luster. A killer Feldspar, some edges have a dusting of small rosettes of Muscovite that add a nice contrast. Better in person, the individual crystals exceed 5 CM diameter.
Fluorite with Quartz
stock #19.1-421
Cantera Llamas, Duyos, Caravia
Asturias, Spain
2.5 x 2.1 x 2.1 CM (thumbnail)
price: $150


Pristine thumbnail of Fluorite cubes having clean beveled edges and a delicate purple hue. The cubes are fully transparent with a slight frosting on some faces which under strong magnification seems to be a complex recrystallization. In perfect condition damage wise, this is a nice example from this small but important locality that has been sporadically producing small numbers of specimens but sometimes of very fine quality. The matrix is perfectly visible through the crystals and the Fluorite is nicely perched at a nice display angle.
SOLD Samarskite (Y) -well crystallized
stock #SOLD 15.1-154
Webb Mine, Yancy County
North Carolina, United States
4.3 x 3.8 x 1.8 CM (miniature)
price: $0


A fan of terminated crystals of dark colored Samarskite nicely perched on a typical Pegmatite matrix. The crystals reach 3.5 CM and seem to be doubly terminated (lower termination is partly hidden by matrix). A nice example of this rare earth mineral from North Carolina, these are not often seen on the market from anyplace. Some adhering Mica is seen on a few faces which could be removed but it seems to add a very nice contrast to the dark Samarskite. In fine condition, usually these are rather crude crystals but this specimen is quite well defined.
Amethyst with Quartz casts after Anhydrite
stock #19.1-284-4990
Frederico Westphalen
Rio Grande do Sul, South Region, Brazil
5.7 x 3.8 x 3.2 CM (cabinet)
price: $160


Elegant form of flower-like Amethyst from the amazing collection of Rock Currier (his label number 4990) . Perfect, 360 degree specimen with the fine esthetics that Rock was well-known for. He imported large quantities of Amethyst from this area and kept just a small but choice selection, of which this is one. The Quartz casts have the square cross section and are hollow as is typical of Anhydrite replacements. This is not exactly the typical form from here and that certainly helped make this a desirable piece for Rock.
Thaumasite
stock #19.1-422
N'Chwanning II Mine, Kalahari Manganese Filed
Northern Cape Province, South Africa
3.1 x 2.6 x 2.1 CM (thumbnail)
price: $650


A sharp and very choice thumbnail of Thaumasite crystals on matrix in excellent condition. The crystals all have a pale color and are transparent with a slightly milky look at some angles. The largest prism is just under 2 CM long. No damage. The best of this uncommon specie was found a few years ago at NChwanning, and those are now quite scarce. This piece is from that find.
Agate -classic locale, fortification form
stock #19.1-392
Ojo Laguna, Estacion Ojo Laguna, Municipio de Ahumada
Chihuahua, Mexico
5.5 x 3.6 x 1.5 CM (small cabinet/ large miniature)
price: $220


A pair of sliced and polished Laguna agates with unusual bright pink, yellow and orange hues. One of the pair is the end piece of the nodule the other is a two sided slice and these match well. Fine and complete all around with no chipping or cracks, Laguna agates are now the most sought after and larger sizes have become very expensive. This is a small cabinet sized older piece that has a strong color palate and reasonable cost.
Elbaite -unusual form
stock #AX-7-464
Jove Lauriano claim, Linopolis, Divinio das Laranjeiras
Minas Gerais, Brazil
5 x 1.4 x 1.2 CM (miniature)
price: $350


An attractive but unusual Elbaite from a little known locality in Minas Gerais, the Jove Lauriano claim. A tapering crystal with a dark top that spreads out holding many tiny terminations. The shaft of the crystal is a translucent to transparent gemmy deep green, it looks dark at first glance but with backlighting the translucency is very evident. It is common to find transparent tops on dark opaque shafts but this is the reverse of that. No damage, a choice yet atypical Elbaite from the Larry White collection, his number 464, according to his catalog obtained from Tony Thurston in 1983. This locality is not well documented but produced a few nice crystals of this habit long ago.
