Andradite var. Demantoid, Gem crystals with color change
stock #17.1-006
Antetezambato, Maherivaratra, Ambanja District
Antsiranana Province, Madagascar
6.5 x 4.9 x 3.1 CM (cabinet)
price: $900
Spring 2017

Top color and luster, bright sparkling gem Garnets are perched on a contrasting matrix of micro Garnets from white to pale green. In perfect condition damage wise, this is far better in person as the crystals are more brilliant than can be photographed. The color change from daylight to incandescent is also quite striking, daylight (or good led lighting) brings out an intense apple green as seen, the last photo shows the color by incandescent lighting. We searched out and examined a lot of the best Demantoids from Madagascar and only a few we consider great values. This is one that stands out.
Calcite with Aragonite- classic locale
stock #16.1-1275
Southwest Mine, Bisbee, Warren District, Mule Mts, Cochise Co.
Arizona, United States
8.8 x 4.9 x 4.8 CM (cabinet)
price: $225
Spring 2017

A choice Bisbee specimen with delicate needle crystals of acicular Aragonite perched on balls of Calcite. From the Southwest mine, this area intersected many voids formed by slumping of oxidized sulphide ore. These voids allowed many secondary Carbonate minerals to form in esthetic growths. As the mining entered these voids some fine specimens were saved. In perfect condition and with good luster.
Sheelite with Fluorapatite on Muscovite.
stock #17.1-AX-15-167
Mt. Xuebaoding, Pingwu Co., Mianyang Pref.
Sichuan, China
8.3 x 5 x 3.4 CM (cabinet)
price: $720
Spring 2017

A really nice combination specimen, with typical Xuebaoding matrix of Muscovite that hosts several yellow-orange Scheelite crystals and a single pink Fluorapatite. The apatite is well exposed and mostly transparent. The matrix was sawn on the back to remove it from the cleft. In good condition, there are very small chips on some Scheelites and the Apatite has a contact on the backside. Fine luster and better in person. Formerly in the Shields Flynn collection of Chinese minerals, vintage 2004 and obtained from Bert Ottens, this type of combo is no longer found. A modern classic.
Fluorapatite on Beryl V. Aquamarine
stock #16.1-167
Alchuri, Shigar Valley, Skardu District, Baltistan
Gilgit-Baltistan, Pakistan
4 x 2.7 x 1.9 CM (miniature)
price: $280
Spring 2017

A fascinating miniature specimen, both unusual and pretty. A 3.2 CM tall well formed Apatite crystal is joined by two gem clear Aquamarine crystals. Both Aquas have some unknown inclusions of brown hairlike crystals and negative crystal forms inside. The Apatite has some inclusions too but less visible as it is milky and mostly opaque. A very nice arrangement and no matrix at all. The condition is very good overall, there are very small contacts on the Aquas and the bottoms of the crystals are incomplete, but the terminations are fine. A very nice association specimen.
Carrollite with Calcite
stock #A-19-257
Kamoya, Kambove, Katanga Copper Crescent
Katanga (Shaba), Democratic Republic of Congo (Zaire)
4.7 x 3.1 x 3.2 CM (miniature)
price: $190
Spring 2017

Carrollite with very bright metallic luster on a nice miniature specimen. There have been no new finds of Carrollite for a few years now, but for a time the Kambove mine was a prolific source for the best specimens ever found. This bright miniature has sharp crystals to 1.3 CM size, there are some contacts and bruises seen on some angles but they are relatively small. More perfect, larger specimens are now trading for many thousands, this piece is a lot more modest but still has top luster and nice form. An affordable alternative that looks much better than the mine run.
Vesuvianite -textbook crystals on matrix
stock #Alec 19-252
Sierra de la Cruz, Municipio de Sierra Mojada
Coahuila, Mexico
8.7 x 4.4 x 4.1 CM (cabinet)
price: $110
Spring 2017

These Vesuvianites are nearly all equant, doubly terminated with a textbook form. Well exposed by etching from contrasting white matrix these are a pleasing golden hue with lustrous surfaces. Back in the 70s these were all labeled Lago de Jaco, but now the correct locale is known to be Sierra de Las Cruz. Most crystals are quite perfect but several have cracked and rehealed or have cracked and split apart while inside the matrix. A good example with many small crystals up to 8MM.
Anapaite- type locality.
stock #Alec 12-192
Zheleznyl Rog, Anapa, Taman Peninsula
Krasnodarskly Kray, Russia
6.6 x 4.9 x 4.3 CM (cabinet)
price: $130
Spring 2017

A good color Anapaite from the type location. This unusual Hydrated Phosphate mineral is sometimes found in association with fossil clams. This specimen has a few Clam fossil segments on the matrix but is mostly about the sheaves of sharp crystals in tight clusters. There is some bruising seen with magnification as is typical but many crystals are quite distinct, perfect and show very good green color. An affordable, moderately rare and attractive specimen.
Cerussite Reticulated twins -classic USA Locale
stock #17.1-AX-551-548
Mammoth Mine, Tiger, Arizona
Arizona, United States
4.9 x 4.3 x 3.1 CM (miniature)
price: $440
Spring 2017

An excellent Tiger Cerussite with classic form, formerly in the Larry White collection, obtained from Shields Flynn. In good condition overall, there is also some chipping damage that can be seen. These bruises are forgivable on such a well formed classic Arizona piece, especially from Tiger. Essentially all of the specimen is Cerussite in twinned habit, there is a small zone of adhering matrix and a painted number from the White collection. Q
