Calcite with Aragonite- classic locale
Southwest Mine, Bisbee, Warren District, Mule Mts, Cochise Co.
8.8 x 4.9 x 4.8 CM (cabinet)
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.
Fluorite on Quartz
5.9 x 4.8 x 3.3 CM (small cabinet/large miniature)
A super sharp, well exposed and choice Fluorite on Quartz matrix. The main octahedral crystal is 2.6 CM across the axis and contrast nicely with the matrix. An older piece from the first wave of specimens produced at Dean mine, this was in the Charles Noll collection. These were exposed by dissolving the enclosing Quartz with hydrofluoric acid, and tricky and dangerous task. This one is especially esthetic and has some zoning. No damage, the Fluorite looks really fine from all angles. Although a lot of these did come out in the 2005-7 era, this quality was never very common.
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
Alchuri, Shigar Valley, Skardu District, Baltistan
4 x 2.7 x 1.9 CM (miniature)
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.
