An incredible, crazy little Tsumeb thumbnail! A ball-like cluster of Calcite rhombs most of which are colored a cadmium yellow. In some other zones the color is deep red from included needle crystals of Chalcotrichite and a few are green from included Malachite. Malachite balls in chains along some areas add a nice green accent making a bright, very colorful specimen. In perfect condition damage wise, this is crystalized all around, a floater. It is not clear what is causing the Cadmium yellow color, it is not typical at all. Ex Hitchings collection dating to mid 1960 vintage. Unique.
Calcite- Complex twin
Daye Iron Mine, Edong Mining District, Huangshi Prefecture
7.4 x 5.4 x 4.2 CM (cabinet)
Worldwide mix summer
From the Daye mining area in 2002 before it became a well known mineral locality, this Calcite has a form unlike later finds. The Calcite is almost 6 CM in diameter, transparent (more so than the photos show) and with glassy luster. Some contacts are noted on the back (see the last photo of the back) but overall as seen it is in very fine condition damagewise. Displays well from several angles, we obtained this on one of of earliest trips to China and until recently it was in my personal collection.
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.
Calcite -complex twinned
Gralex Quarry, Mont-sur-Marchienne, Charleroi
3.4 x 3.4 x 2.3 CM (small miniature)
A choice small specimen from this noted locale. The Calcite is undamaged, mostly transparent and shows complex twinning. This locale produced many habits and some top pieces over the years, but it is now finished. This is a small, cute, affordable piece from this important locality with a nice arrangement.
Manganocalcite- Pagoda Style
Manoshan Mine, Dongpo, Suxian District, Chenzoh area
10 x 9.1 x 5.3 CM (cabinet)
Pagoda style calcite towers formed of stacked flat disklike rhombs. The color is a pale pink and the Calcite has a vivid red Fluorescence. Very sharp and undamaged on the display face, broken on the back underside where it was removed. An older specimen ex Shields Flynn collection, from a 2004 find. In this fine condition, these are very uncommon, and very esthetic in any sort of display.
stock #17.1- 125
6.7 x 4.7 x 4 CM (cabinet)
Pre Holiday 2017
A stacked habit style of Calcite from a 2016 find in Fujian, China. Resembling a pagoda or a stack of umbrellas, this habit is very distinctive, and this small cabinet specimen is in excellent condition. A delicate pink to tan color, this turns a vivid red in SW ultraviolet light. The cap or top of the stack has an especially odd form with a zoned inclusion.
Calcite in Fossil Clam
stock #Alec 19-286
Rucks Pit, Fort Drum, Okeechobee
9.4 x 8.8 x 5.7 (cabinet)
Pre Holiday 2017
A far better than average specimen of the remarkable Calcite in Clam shell fossil from the renowned Rucks pit. This was once a prolific small quarry and produced many of the Miocence age fossil Clams. Now closed to collecting and reportedly exhausted, this was a unique deposit. This example is a perfectly complete shell, well defined and showing the Clam exterior replaced by tiny Calcite crystals. The inner void is seen through an opening at the hinge and shows well formed gemmy amber color Calcite prisms to 3.1 CM long lining the inside. These were plentiful in the past, but fine, perfect examples like this were never common and are now especially desirable and rare.
This is a choice Shullsburg Calcite with the classic stepped Scalenenohedral crystals that have enlarged clear prismatic terminations. Far more transparent in person this has glassy luster and faint phantoms of internal Pyrite crystals. In excellent condition the only damage is the base and back lower edge area where this was removed. A choice older specimen, these are modern classics and this is like a textbook example of epitaxial alignment of prism faces.
