SOLD Grossular on Diopside
stock #SOLD 21.1-056
Orford Nickel Mine, St-Denis-de-Brompton, Estrie
4 x 2.3 x 1.9 CM (miniature)
Late Summer 2021
An unusual and cute Canadian Garnet specimen from the Orford Mine. A 1.7 CM honey-brown Grossular is resting on and included by crystals of Diopside. The Orford Mine is well-known as the source of Chrome green Grossular and Diopside specimens. The usual Grossular from here are micros rarely reaching up to 3mm in size, typically forming a sparkling druse. Larger crystals like this are very rare, I do not know of another this large and complete.
Wulfenite with minor Mimetite
Rowley Mine, (Reliance Mine), Theba, Painted Rock District
5.3 x 3.4 x 1.6 CM (small cabinet/ large miniature)
Late Summer 2021
Delicate and fine windowpane crystals of Wulfenite stand up from the matrix in a complex array. Very sharp, intense color and with glassy luster, the Wulfenites are all fully transparent. A few tiny balls of Mimetite are present but they are minor in comparison to the Wulfenite. In incredible condition which is amazing given the fragility of the crystals. From the final specimen recovery operations at the Rowley. This can be shipped safely (not recommended however for international orders). If requested we can hand deliver at a major mineral show. Much better in person, the bright luster is hard to fully appreciate on a computer screen.
Strontianite on Barite
Minerva #1 Mine, Cave-in-Rock, Hardin County
10.6 x 7.7 x 5.3 CM (cabinet)
Late Summer 2021
Superb combination specimen of Strontianite crystal ball-clusters on contrasting Barite blades. A classic southern Illinois specimen that is far more esthetic than typical for these species. The famed Fluorites from this mine tend to overshadow the excellent (and more rare) Strontianites. In perfect, undamaged condition, the Barites are in two generations and have a pale blue hue while the Strontianites in "puffball" form are a pale yellow creme color. In person the luster and sparkle are especially impressive. Strontianite is not usually a very attractive mineral but is respected especially from the classic localities on Europe, but not often an attractive specie. This specimen that is as fine as can be found from the USA and far more attractive than usual.
A fine, large doubly terminated Apatite crystal sits on an orange Calcite matrix. The Apatite is well-formed with the typical slightly rounded edges and two different types of termination. Fluorapatites are fairly common in the scattered Skarns of this region but substantial crystals like this are not found very often. There are some minor contacts but overall this is a distinctive textbook form crystal with some areas of glassy luster. A modern classic.
Malachite pseudo after Azurite - USA classic
Sacramento Mine, Bisbee, Warren District, Mule Mtns, Cochise Co.
3.8 x 3 x 2.3 CM (small miniature/ large thumbnail (toenail))
Late Summer 2021
A textbook perfect pseudomorph that has the exact form of the original Azurite crystal fully altered to a velvety Malachite. A few tiny bits of Cuprite and Copper are seen with strong magnification on the gossan matrix, but overall this is all about the very fine Malachite. A classic US specimen from the Sacremento Mine at Bisbee, we are told this is from a pre 1929 collection but there are no old labels. Certainly no specimens of this quality have been found for many decades, and will not be seen again.
Two different forms of Fluorite on Calcite matrix sprinkled with Chalcopyrite crystals. The Fluorite cubes are very sharp, gemmy zoned and vividly fluorescent. The pink portions of the Calcite are also fluorescent making a nice contrast of purple, red and cream colors. The Fluorite cubes are up to 8mm in size and in perfect condition. The cores are a yellow hue with a blue outer zone. We almost never see this locality represented in Fluorite collections but it is clear it was capable of forming some very nice crystals.
A transparent and nearly pure crystallized Pollucite that has been heavily etched. Aside from some tiny inclusions this is all Pollucite with total transparency, and curved crystal faces. Pollucite is one of the few sources of Cesium and sometimes also includes substantial amounts of Rubidium, it is an uncommon gemstone as well. The specimen is broken on the base or underside where it was attached but the visible surfaces are in fine condition and show the characteristic Pollucite structure and luster perfectly. This is just under 36 grams of gem crystal that is very lustrous in person.
A nice combination specimen of dark green (nearly black from some angles) Quartz clustered on Andradite. The Garnets are tiny sparkling orange color and make a nice contrast. In very good condition as seen, the Quartz shows the classic form where it gets wider toward the termination, yet is not a scepter. Presents well from several angles with a good balance.
