Fluorite - gem clear
Penfiled Quarry, Penfield, Monroe County
3.2 x 2.3 x 2.3 CM (thumbnail)
An ultra clear sharp and glassy Fluorite cube perched on Dolomite. Choice thumbnail or small miniature of a Penfield New York Fluorite, this was collected more than two decades ago. Flawless with no damage at all even under strong magnification. The matrix is clearly seen through the Fluorite, which I would describe as a clear colorless ice. In some light however a very slight hint of blue is seen. A modern USA classic, New York Fluorites are relatively rare, and are prized when perfect and esthetic.
Mibladen Mine, Upper Moulouya lead district, Midelt, Khenifra Province
4 x 3.4 x 2.2 CM (miniature)
Among all the nice Vanadinite that has come from Morocco, a few pieces do stand out as having a next level of color, form or general impact. This is an outstanding miniature with that intense red color, bright luster and sharp, free standing crystals. The overall composition is attractive from almost any angle, there is just a little matrix that adds nice contrast. With the past few years production of Moroccan Vanadinites it is easy to take these for granted, yet they are clearly superb and one of the best values in the mineral market. No damage.
Calcite -"Mushroom habit"
Fengjiashan Mine (Daye Copper Mine), Edong District, Daye County, Huangs
7 x 5.4 x 4.3 CM (cabinet)
From a find in 2005 in Hubei, these mushroom like Calcites made big news then in the mineral world. We sold this example at that time and it is now back with us to be offered again. This is colored on some faces by inclusions of Hematite which adds a nice contrast. The display face is in fine condition with no visible damage, but there is a notable cleave on back of the left side that is seen from that side, and the bottom is broken at an angle so the base is also cleaved. Despite that cleave this is still an attractive displayable specimen that shows the form perfectly. The "stem" has a series of flat Calcite tabular crystal ridges that are more deeply colored red.
A striking color zoned Calcite from the San Antonia Mine, Santa Eulalia. This was mined about 20 years ago, and shows two generations of Calcite with different habits. Brilliant red color and with bright luster, the red is most likely from Hematite. The display face is in excellent undamaged condition, the only damage is along the outer edges where it was removed but even that is minimal. A distinctive, colorful Mexican piece that is much more impressive in person.
A sharp, complete and perfect textbook form Cobaltite crystal from the classic locale of Tunaberg (Sweden). The worlds best Cobaltites have come from two localities in Sweden, Tunaberg and Hakansboda. This has a trace of Chalcopyrite on one face which is more typical of Tunaberg specimens. Well above average quality, the luster and form are impeccable.
Duftite on Quartz
Black Pine Mine, Flint Creek Valley, John Long Mts., Granit Co.
12.8 x 9.3 x 4.2 CM (cabinet)
A large plate of Quartz crystals up to 2 CM in size are thickly coated with Duftite in olive-green spheres. An old specimen from the Black Pine Mine that is famed for the great Veszelyite finds there. I have not seen another specimen quite like this from any USA locality it looks like a dark botryoidal Tsumeb Duftite on a Montana Quartz. An unidentified coating of brighter yellow is also present and adds some contrast. it is a very significant and sizable Duftite specimen with a lot of character. In good condition overall there are a few tiny chips on some Quartz but most are perfect and undamaged. The Black Pine mine has a complex and wonderful mineral assemblage including many uncommon associates. This piece is significant for the locale is the best USA Duftite I know of. Ex Chris Amo collection.
Calcite with Realgar inclusions
Shimen (Jiepiayu) Mine, Shimen County, Changde Prefecture
Simply incredible! A brilliant red cluster of calcite on matrix with small realgar crystals. Killer esthetics. We obtained this at the mine in 2003 and sold it shortly after- it was the best of the find. Since then we have not seen anything like this. We are pleased to have it back again for resale, The largest calcite crystal is 7.2 CM, and the piece displays well from multiple angles, but it does have a cleave on the backside. The red color on the calcite is from both a coating and inclusions that is primarily realgar, some recent analysis of similar materials have fund trace amounts of some rare rsenic minerals, this one has not been tested for those. Really striking color, the display side has no noticable damage. This will really jump out of any calcite display!
A super sharp cluster of dark Mercury rich Tetrahedrite crystals on contrasting matrix. A classic specie and locale, this Schwatzite shows perfectly the form and habit. The individual crystals are roughly 1 CM which is very large to be this sharp and perfectly defined. Most larger crystals are more crude or have secondary coatings. Schwatzite is not a specie but a variety of Tetrahedrite which can have Silver, Bismuth or other enriching elements and hence distinctive appearance. The Mercury rich variety seems to always have this form and color and as far as I know is only found at this locality. A choice, very old and undamaged specimen.
