Copper in Calcite
Onganja Mine, Windhoek District
4.9 x 3.8 x 3.5 CM (miniature)
An exceptional (and very unusual) Copper in Calcite from the great Onganja Mine. A large sharp transparent Calcite 3.8 CM across sits on and is included by Copper. The matrix is partly Copper, Malachite and Chalcotrichite. The Calcite is unlike most from Onganja as it is a simple modified rhomb without the complex habits or twinning that is typical from here. This displays well from most any angle, in very good condition with only very minor rub spots. The Onganja mine was once a prolific source of fine Coppers, Cuprites etc but the Calcites were always especially rare and sought after. The mine has been closed and flooded for years. This specimen is quite striking in person and a significant Copper.
A neat miniature hosting a fine Dauphine twin Quartz that has gem clear transparency. A New England classic, these are often compared with the well-known Colorado specimens but are quite different in person. the matrix is well crystallized Amazonite, with the blue green color most desirable from New Hampshire. Ex Ernie Schlichter collection, this was collected by him in the heyday of the Government pit digging. The luster is excellent and glassy on the Quartz and a pleasant matte finish on the Feldspars making a nice contrast.
These are from an old stash and are not at all common on the market
Elbaite- gem crystal
Pederneira claim, Sao Jose da Safira
4.2 x 1.1 x .8 CM (miniature)
Bright green to blueish glassy luster tourmaline crystal in excellent condition. Nearly all gem grade, this weighs 6.5 Grams, and has only a few minor internal veils. Excellent example of this style from the great Pederneira Mine, there are no chips or flaws on the entire prism or termination, althouh this is inclomplete on the bottom end where it came from the matrix. That is not visible when displayed.
A bizzare, unique, rare but attractive Aquamarine. From the Erongo Mountains, (Hohenstien Massif) this is a complete, doubly terminated crystal. The flat termination is typical although in this case the corners have modified faces. The real interest is the other termination that is a series of hexagonal steps that are perfectly centered like a stairway or a turret. The 4 main steps or platforms are very flat and some edges have a little etching, the whole is therefore a reversed scepter. Some minor contacting/chipping is noted but overall the condition is excellent. A good display piece but especially a great addition for a suite of Namibian/ Erongo minerals, Beryls or exotic crystal forms.
Calcite -Gem clear with phantom
Leiping Mine, Leiping, GuiyangCo., Chenzhou Prefecture
4.1 x 3.6 x 2.5 CM (miniature)
Bright luster, exceptional clarity and sharp form, a choice miniature from the now famous Leiping mine. In perfect, undamaged condition, this mine is famous for these superb Calcites and the bright Hematite phantoms. Very few have been available in recent years. Similar in form and habit to the classic English Calcites from the Iron fields in Egremont, these are far less expensive yet just as attractive.
A textbook perfect miniature specimen with an impact far bigger than its size. While the external form is outstanding, the insides of the Fluorites clearly show incredible, sharp, inclusions of perfect pink Dolomite rhombs. The matrix of Dolomite, Calcite and Sphalerite adds nice contrast to the glassy Fluorites. In perfect condition damage-wise which is very rare. Some faces show a secondary etching while others are perfectly smooth and transparent. The 26 sided crystals are a perfect model for this less common habit. Best appreciated in person, a very choice example of why Huanggang is the most significant mineral locality in China today.
A killer Paradamite with outstanding color, form and with contrasting Smithsonite. Paradamite is a very rare mineral and choice pieces are not often available for less than a small fortune (sometimes even a large one) From the recent find, this has the best glassy luster, several crystal habits showing and the quality is top. The last good find of Paradamite was almost 20 years ago, and disappeared right away.
Pyromorphite -hoppered crystals.
Daoping Lead-Zinc Mine, Yangshao
Guangxi Zhuang Autonomous Region,
4.8 x 3.8 x 2.7 CM (miniature)
A pretty Pyromorphite with better than average, very distinct hoppered crystals on smaller prisms. From late finds at the amazing Daoping mine, this is a not the typical color from here, it is more like an olive green hue in person. Choice and in excellent condition, Daoping has become a great modern classic locality and this sort of Pyromorphite shows why.
