6.6 x 4.3 x 4.2 CM (cabinet)
A big 3.6 CM Zircon crystal is perched on a hard matrix. Most faces are rather lustrous, sharp and the crystal is unusually large. There is contacting on the back and some edges, so this is not a perfect textbook form, but this still presents well and is impressive. There are transparent and translucent areas and has a good UV florescence. The red color in some areas is very well pronounced. From a find over a decade ago.
Violet crystals of Fluorite with complex rounded faces most of which are on and included by Schorl crystals. A scattering of small Quartz and Goshenite. In excellent condition, bright and lustrous, the Fluorites have color zoning in areas with a darker red-purple and these all glow with any backlighting. A clean and attractive Erongo piece that can be displayed from almost any angle.
Very odd yet attractive specimen of two Fluorite crystals that are both pierced by scalenohedral holes in the shape of former Calcite crystals. The cavities are filled with drusy Quartz crystals that sparkle and contrast with the green Fluorite. An unusual Fluorite from the Dongpo Mine, this has 2 larger and 3 smaller casts inside the Fluorite cubes. A nice piece for those who enjoy oddities.
A very clear, sharp and lustrous Aquamarine collected in the 1940's by Warren Johannson. From the famed Mt Antero location which is a magnificent, high elevation pegmatite. In fine condition this is a pale green-blue color and fully transparent.
An early Shangbao specimen with very unusual color. The Fluorite is an iridescent, yellow to orange, and has well-defined faces. The color seems to be due to an oxide coating that is only partly inside the Fluorite. The back of the specimen is cleaved and shows that the Fluorite is colorless inside. Most Shangbao Fluorites have been typical purple and green, so this is very unusual. The cleaved backside keeps the costs of this piece much lower but is not visible on the display side. We have never seen another with this habit/ color from Shangbao.
Milpillas Mine, Cuitaca, Municipio de Santa Cruz
3.3 x 2.3 x 1.6 CM (thumbnail)
A sizable thumbnail of Brochantite from the earliest find at Milpillas. This has the mixture of very slender hairlike crystals and the more stout, thicker ones. Excellent color and condition. We saw very few good thumbnails sized pieces of Brochantite from Milpillas as most were quite large. The Brochantites found at this locale were quickly hailed as world-class and set new standards. This small piece is a choice example that is a perfect, tiny part of this important discovery.
Fluorite - USA classic locale
May Stone and Sand Quarry - Fort Wayne, Allen County
5.8 x 4.9 x 4.7 CM (cabinet)
Gemmy, sharp, pale yellow Fluorites on a blocky Dolomite matrix. The largest crystal is 1.4 CM and has a very glassy luster. This area of Indiana is very different in terms of mineralogy from the famed Southern Illinois Fluorite districts. Water-clear crystals with very flat faces and sharp edges are more typical at this locale and good specimens are far more rare. A nice older piece that is much more lustrous in person.
Bou Azzer District, Tazenakht, Ouarzazate Province
Souss- Massa- Draa Region,
7.4 x 7.3 x 4.9 CM (cabinet)
Vivid magenta-pink crystals of Cobaltoan Calcite clustered in an esthetic mass. The crystals are just over one CM in length (one is 1.6 CM)and are sharp, transparent and have a slightly textured or silky luster. In excellent condition overall, this is from a major find about 6 years ago. Cobaltoan Calcites are really only found in fine specimens at just two localities worldwide and currently neither place has produced specimens for some time. In Morocco there have been only three important larger finds in more than 40 years, and the most recent productive zone is currently flooded. Very good value for color and form.
