San Francisco Mine, Cucurpe
6.8 x 5.9 x 4.3 CM (cabinet)
An old Mimetite specimen from the famed San Francisco mine that is better known for exceptional Wulfenites. The crystals on this specimen are unusual in that they are elongated, standing hexagons that look more like a yellow Pyromorphite than the usual orange Mimetite balls. Overall in fine condition, examination by loupe finds very few tiny bruises mostly at the edges. Overall this is a a very well defined and esthetic Mimetite with what seems to be two different generations. The matrix is a solid and substantial "non crumbly" type unlike the matrix of most Wulfenites from here. This piece has Mimetite crystals on all sides the color ranges from greenish brown to mustard yellow, quite different from the orange Mimetite balls more often seen from this mine.
Chalcopyrite on Calcite
Concepcion del Oro
9.7 x 7.4 x 6.4 CM (cabinet)
A large scalenohedral Calcite crystal is encrusted with Chalcopyrite crystals many of which are dusted with sparkling drusy Quartz. The Chalcopyrite is mostly coated with dark Bornite patina which makes a strong contrast as well. Aside from a few very small bruises the Chalcopyrite is in fine condition, has classic good form and overall is a very esthetic example from this famed locale. Ex Charles M Noll collection, I have never seen a better example from Concepcion del Oro, and this is a super esthetic Chalcopyrite from anyplace.
Nakhlak Mine, Madan-e Nakhlak, Anarak Dist., Nain Co.
4.3 x 3.9 x 3.7 CM (miniature)
Interconnected reticulated twins of smokey color Cerussite showing fine classic form. The crystal twins are all in perfect parallel position and aligned in stacks showing the geometric precision of a snowflake. The Nakhlak Mine had a major find of Cerussites about 2 years ago, the better pieces showed this quality of form and condition. This is more or less a floater, complete on all sides, no real points of attachment. From many angles this is quite perfect, undamaged but on close inspection the backside and edge have some very minor contacts/chips best seen with magnification. Given how delicate the mineral is this is incredible. Until this find any Cerussite of this quality would be far more costly, easily in the 1-2K range, but enough were found that these are now very reasonable in costs while they last.
13.7 x 2.5 x 1.9 CM (cabinet)
A large, quite old German Hematite of the type we call "pencil ore" but are also called "swords" . This has the original label from the Philadelphia Acadamy collection with notation of the donor, John Hartman (1840-1910). We know that Hartman made bequests to the Acadamy between 1879 to 1905. Three older affixed collection numbers are on the specimen as well, so it is certainly much older than that. It is likely there was some confusion regarding the locality as it is listed as Glaskopf, Saxony, probably being copied from a small nearly illegible label on the specimen. At one time the word Glaskopf referred to a form or habit of Goethite and Hematite and not a locality that we know of. Regardless of that detail, this is a nice and sizable example of an early German Hematite with classic form, color and provenance.
Doubly terminated Quartz crystals with classic "Cumberland" form in a cluster dusted with small Hematite crystals. In incredible condition, this certainly looks like a superb vintage English specimen but it is much more unusual, being from Chubb Lake in Northern New York, USA. The locality has been closed for some years but during a brief period some amazing specimens were found. This habit was wrongly called "Beta Quartz" for a time and many old labels reflect that. This specimen has fine form, the crystals are undamaged, it is possible to see inside the Quartz through glassy faces to see dense inclusions. Not often available, this was in the William Hladysz collection.
Balydonite -classic locale
Penberthy Croft Mine, St. Hillary
8 x 6.7 x 4.7 CM (cabinet)
A colorful and attractive very old Balydonite specimen from Cornwall with rich density. Ex Lechner collection (Austria) a mid to late 19th century collection that had also absorbed several earlier collections. The collection was dispursed in 1940-50 era. In 1969 sold to John Marshall via Schortmanns. This specimen is well over 100 years old, perhaps much older. The original label does not specify the mine but with the Lechner collection number (7132-13-23) it can be confirmed that this is in a sequence from the famed Penberthy Croft, and the habit etc is a perfect match for this location, which is also the type locality. The mine closed in 1840. There are several other species present that are not identified but what appears to be an area of Cornubite is noted as is some areas where the Balydonite has partly covered by a bluish-white mineral. Overall a choice classic example that has several possible display angles. Labels from Schortmann and Marshall are included.
SOLD Astrophyllite- rare Northeastern USA
stock #SOLD 20.1-166
Hurricane Mountain, North Conway, Carroll County
3.7 x 1.6 x .5 CM (small miniature/ large thumbnail (toenail))
A remarkable cluster of Astrophyllite crystals that at some angles looks almost like Brookite mass. No matrix and with a good brassy iridescent luster, this is the best example I have ever seen from the Northeastern USA, and very fine from anyplace. Collected by Les Hitchings sometime in the 60's on Hurricane Mountain, this is very unlike typical specimens that are more micacous or fibrous and lay flat on encasing matrix. Some references list Astropyllite as a "very rare" Potassium, Iron, Titanium Silicate mineral, but in recent years there have been many specimens from the Khibiny Massif coming out, so this is no longer such a rare specie. However, well defined crystals are still rare and this is a very choice example. The ends have some bruises or contacts but overall this is fantastic for a USA specimen.
This is not at all a typical Kyanite, the crystals are vivid blue, gem clear and are sharply terminated. Well presented on a massive Quartz matrix, these crystals are perfectly exposed and brilliant in person. With backlighting this glows an intense blue hue. Some zoning is noted with the "stripes" of clear and deep blue running along the C axis of the crystals. Huge amounts of Kyanite come out of Brazil but super gem grade display pieces are very rare, this is a superb example with a lot of display impact. Better in person.
