Rhodochrosite with Quartz
Wutong Mine, Liubao, Cangwu Co. Wuzoh Pref.
2 x 1.6 x .8 CM (thumbnail)
Small, but very cute, cluster of sharp and slightly-etched Rhodochrosite rhombs. Several faces show complex stepped modifications that add extra pop. Aside from a tiny spray of Quartz crystals, there is no matrix, just Rhodochrosite. This thumbnail from an important find at Wuzoh in 2009, this was one of the last of this form, as most later pockets have more flattened and disk-like crystals. Nice color, form and presentation, if this was larger, it would be a very costly specimen!
A single black octrahedral crystal from vintage 1930's ex. Warren Johansson collection. Dr Johansson was a prolific field collector and active trader well into his nineties. His label is with the specimen. Very nice face modifications and a slight melted look as is classic for the specie. Most Frankinites have considerable damage or are incomplete, but this one is all there, with only minor edge rough spots and one clean contact. Of course this is from the type locality which is really the only source of any sizable crystals worldwide, yet these were at one time plentiful in Franklin. A nice piece that can fit a Thumbnail box but just barely.
Crocoite on Gibbsite
Adelaide Mine Dundas Mineral Field, Zeehan District,West Coast Municipal
9.5 x 6 x 2.6 CM (cabinet)
Slender bright red-orange crystals of Crocoite rise above a contrasting white Gibbsite matrix. A choice specimen with most crystals in good shape, terminated and a few with hoppered form. Minimal damage as is almost inevitable with this sort of fine needles, but most is not visible by naked eye. From a 2014 pocket, this has the color and luster that is most desired, the needles are up to 1.6 CM.
a cluster of sharp Babingtonite crystals perched nicely on a matrix of Prehnite and clear Quartz crystals. The Babingtonite has good mid range natural luster, in our experience the very bright luster on some pieces is often a result of an oiling or plastic coating, which is for us a form of fakery.
This is clearly a fully natural specimen ex Shields Flynn collection. For almost a century the wolds best Babingtonites were from a small quarry in Western Massachusetts. Very few were ever found of this size and quality. Even today a specimen from Massachusets this fine would be sold quickly for thousands. The Chinese discovery has allowed many more people to own a choice piece for reasonable cost..
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.
Esfahan (Ishfahan) Province,
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.
