Selenite with Herbertsmithite inclusions
stock #16.1-535
Rudna mine, Lubin, Legnica
Lower Silesia, Poland
8.3 x 7.8 x 7.3 CM (cabinet)
price: $1150


A well crystalized cluster of Gypsum I(Selenite) with rich green inclusions and encrustations of the rare mineral Herbertsmithite. This find has produced what are certainly the most esthetic examples of this specie as Herbertsmithite is not usually a "display" grade mineral. Recently Herbersmithite was found to have unique properties of changeable magnetism and with quantum spin properties. This was picked up in some of the popular media and somewhat exaggerated as news, even being called a "new form of matter". There was a brief period where tiny crumbs were being sold for high prices. Despite the inaccurate hype this is a remarkable mineral and on this specimen it is actually attractive.
SOLD Bournonite - Cogswheel type crystals
stock #SOLD 19.1-856
Colavi Mine, Machacamarca district, Cornello Saavedra Province
Potosi, Bolivia
3.1 x 2.6 x 2.4 CM (small miniature/ large thumbnail (toenail))
price: $0


A fine complete cogswheel cluster of Bournonite crystals that is perfect on all sides, undamaged and with classic gunmetal luster. Bournonite is a delicate mineral and perfect clusters of this sort are quite rare. A tiny bit of adhering matrix gives some nice contrast. This is a very fine and unusually sharp specimen from Bolivia that really looks just like a vintage Herodsfoot specimen. From recent mining this is obviously far less expensive than the English classics!
Amethyst -scepter with Rutile inclusions
stock #19.1-855
Karur
Tamil Nadu,
3 x 2 x 1.3 CM (small miniature/ large thumbnail (toenail))
price: $340


A delicate slender scepter of well formed Amethyst rises from a cluster of smaller crystals. Very fine esthetics and good color in perfect condition. The scepter is included by red needles of Rutile best seen in the clear parts of the head. This specimen also has the rare hexagonal hole or negative crystal in the top of the termination, this is especially impressive with magnification. Despite the small size this has a strong visual impact and is especially choice on close examination.
SOLD Scheelite with Fluorite
stock #SOLD 19.1-854
Dongpo Mine, Yizhang County, Chenzohou prefecture
Hunan Province, China
3.7 x 2.8 x 2.3 CM (miniature)
price: $0


Sharp white octahedral Scheelites cover most of this matrix along with a sharp Fluorite and some scattered Calcite crystals. In fine condition from the Dongpo mine, a locality better known for large Fluorites. This is from a small find made this fall, these are the first Scheelites I have seen from Dongpo, It has some similarities to an older find at Huangshaping mine not very far away.
Vanadinite - large hoppered crystal
stock #19.1-853
Mibladen Mine, Upper Moulouya lead district, Midelt, Khenifra Province
Draa-Tafilalet Region, Morocco
3.2 x 2.1 x 2 CM (small miniature/ large thumbnail (toenail))
price: $180


A super sharp geometric sculpture formed by the hoppered faces of this hexagonal crystal. This year there was a major find of very find Vanadinites in Mibladen, probably the best pocket ever found. Large bright red crystals in large numbers were found in several habits, this has an especially esthetic form and is a textbook example of face hoppering. Excellent color with some faces slightly more intense red than others as is typical in this find.
HOLD Rutile on Hematite -epitaxial twins
stock #HOLD 19.1-822
Novo Horizonte
Bahia, Brazil
3.3 x 2.7 x 1.2 CM (miniature)
price: $290


A complete six ray star of golden Rutile needles radiating from a flat bright Hematite crtystal. Two small additional Hematites with Rutile are also present.Fine Brazilian Rutile twins on Hematite crystals are one of the mineral kingdoms wonders. This can be displayed from either side though the view shown is my preference. A choice textbook example of this wonderful crystal habit.
Rutile on Hematite -epitaxial crystals
stock #19.1-821
Novo Horizonte
Bahia,
4.3 x 3.9 x .9 CM (miniature)
price: $170


Fine Brazilian Rutile twins on Hematite crystals are one of the mineral kingdoms wonders. This specimen shows well the mirror bright Hematite crystal with a flat habit hosting radiating golden Rutile needles. In fine condition as seen, the specimen can be viewed from either side and shows textbook quality the star radiating form with epitaxial alignment. Choice.
Barite - Classic locale
stock #AX-10-798
Pohla Mine, Schwarzenberg District
Saxony, Germany
6.1 x 4 x 3.6 CM (cabinet)
price: $390


A very attractive Pohla Barite showing the recognizable form of a chisel-tip termination and gemmy golden tops. The very glassy prisms also show the dark inclusions in the lower sections that give a nice contrast. The tips are fully transparent and the main crystal is doubly terminated. Displays well, this looks in good condition but is not perfect (very few are when examined closely) this has some edge chipping seen with magnification that also helps keep the price low. While not for perfectionists it is still a pretty example from a famed German locality and affordable.
