Inner Mongolia Region,
3.8 x 2.6 x 1.7 CM (small miniature)
Pentahydroborite is a rare Hydrous Calcium Borate, that has only been found a few times in very few widely scattered small deposits. The most recent finds were in the 1990s in Japan and in a single pocket in 2014 in Inner Mongolia. There have been no more since. This piece is well crystallized and is in excellent undamaged condition from Inner Mongolia. There is a little Wurtzite that adds some contrast as well. The crystals are in two different habits and some are in leafy groupings.
Large, sharp, and very translucent, this single crystal of Parisite is exceptional. The bright red brown color and glassy luster make this stand out. Parisites have been found sporadically at the Emerald mines near Muzo, but usually much smaller, damaged or opaque. This is a textbook example of the tapering habit seen at Muzo. Perfectly eye clean for damage but very tiny chip can be found with 20X magnification. In 15 years of travel and worki with Colombian minerals, this is the best single crystal of Parisite we have had.
A super, small specimen in excellent condition and with top grade color. Sharp form, undamaged and un-repaired, larger specimens with this quality cost thousands. Excellent value for a vibrant, classic USA Microcline.
From the famed Bunker Hill Mine, this is a choice small specimen of sharply crystallized Cerussite with a few small Anglesite prisms as well. Both twins and single crystals are noted. The matrix also includes some small bits of Linarite and what looks like Caledonite in spots on Cerussites. Choice cognac color and sharp form protected in a shallow vug. The condition in the vug is good, the only notable damage is outside the vug itself. Choice for the locale and an attractive Lead secondary from this famed Pyromorphite locality.
The distinctive "pineapple" style Calcite from Shangbao came out sporadically in the 2000-2008 era, this is a very choice example of the habit. Set on a matrix of sparkling Quartz the addition of a few scattered purple Fluorites adds extra contrast. In fine condition as seen, the terminations of the Calcites are transparent and the body of the prism is more milky, all with the "pineapple color". Top Shangbao Fluorites are now regarded as some of the worlds best (and most expensive). 15 years ago at the mine the Calcites were more expensive from the miners than Fluorites because they were more rare and hard to extract intact. Times change.
Apatite on Muscovite
Chumar Bakhoor, Hunza Valley
Gilgit, Northern Areas,
5.5 x 4.5 x 4.1 CM (cabinet)
A prism of pink Apatite (Fluorapatite or Apatite-CaF)is nestled in a Muscovite matrix. The crystal is 2.1 CM across and has distinctive modifications of the edges of the termination. From the earlier finds of Apatite at Chumar Bakhoor, this is in excellent condition. Esthetic contrast with the matrix, the Apatite looks fine from all angles.
A starburst of glassy Hemimorphite crystals with the extra attraction of being a nice pale blue color. From 2015 finds in Mina Ojuela, this is an especially fine and esthetic specimen. Some of the best Hemimorphite ever found comes from this locale, but very little ever had this most desirable blue color. The individual prisms are up to 1.1 CM long and have a bright glassy luster. Choice and very rarely available in this quality.
