Proustite-classic ruby Silver
stock #18.1-322
Shaft 207, Niederschelm, Schelma, Schlema-Hartenstein District, Erzgebir
Saxony, Germany
1.6 x .7 x .6 CM (thumbnail)
price: $300
Late Summer 2018

A complex single crystal of bright red Proustite and just a tiny speck of adhering matrix. Classic Ruby-Silver, from the German Erzgebirge, this has very good luster and the red color shows no sign of fading. Close exam with magnification finds some chipping but most of the crystal faces show good form with glassy striations. Much better in person, this is a choice thumbnail at a very reasonable cost for this highly desired Silver mineral.
Kammererite- Brilliant red-purple crystals
stock #18-AX-30-033
Kop Krom Mine, Kop Daglari
Erzurum Province, Turkey
7.8 x 3.8 x 2.4 CM (cabinet)
price: $1100
Late Summer 2018

A killer in person, top quality chromian Clinoclore (Kammererite) in a quality that is simply not available anymore. Outstanding, unusually brilliant, rich deep purple Kammererite in large well formed crystals. These are transparent gem grade, sharp and in perfect condition. It seems there will not be anymore Kammererite from Turkey, even average pieces are now hard to get classics. Widely regarded as the very best ever found, the Kammererites of Kop Krom stand out worldwide. Most specimens were druses of very small crystals, pretty but not exceptional. However, this specimen has many big 7-8 mm plus sized prisms on a bright druse. Eyecatching display piece that is one of the best in this size.
Cerussite covered by Pyromorphite
stock #0097-JM-3854
Schapbach, Black Forest, (Wolftal)
Baden-Wurttemberg, Germany
7.2 x 5.9 x 3.2 CM (cabinet)
price: $390
Late Summer 2018

Exceptional quality for this less well known locality. The matrix is almost all Cerussite in many crystal forms, with a small area of Galena nearly all covered with tiny Pyromorphite crystals. The matrix also has a dusting of very tiny clear Quartz in doubly terminated crystals that add a lot of sparkle. There are other Phosphate minerals on the specimen that are not identified. The Pyromorphite ranges from pale yellow to green hues and the whole is very colorful. The shapes of some Cerussite twins are well defined but brightly colored by the coating of pyromorphite. This all makes a very fine look under magnification. Ex John Marshall, Heinz Stempel
Chrysoberyl -Classic, Co-type locale
stock #18.1-407
Chrysoberyl Locality, Middlesex Turnpike, Haddam
Connecticut, United States
2 x 1.7 x 1.5 (thumbnail)
price: $450
Late Summer 2018

A small but significant Chrysoberyl from the Haddam Connecticut locality that was the first place the mineral was found in situ in 1810. Mindat offers a detailed report on this long closed locality that makes great reading. https://www.mindat.org/loc-213971.html The main Chrysoberyl on this matrix is .8 CM and is sharp, translucent and a good yellow-green. Ex Larry White collection, these old Chrysoberyls are not often available. The collecting was most active in the early to mid 19th century and it seems by 1901 the original spot was no longer accessible. A choice classic thumbnail for this important locality.
Wulfenite -classic
stock #13.1-079
San Francisco Mine, Cucurpe
Sonora, Mexico
3.2 x 2.5 x .6 CM (small miniature/ large thumbnail (toenail))
price: $725
Late Summer 2018

A large complete crystal (with several coating both sides) in fine condition from the famed finds at the San Francisco Mine, Sonora, Mexico. Colorful and transparent, the luster is glassy and the lack of damage is remarkable. These Wulfenites with large crystals like this were all collected more than two decades ago. They were (and are) very fragile, so fine complete larger crystals were uncommon. A choice and showy crystal, these have gotten very expensive and harder to find.
Amethyst -zoned scepter
stock #18-AX-12-193
Murzinka Mine,Sarapulka Dist., Sverdlovskaya Oblast, Middle Urals
Urals Region, Russia
2.7 x 2.2 x 1.9 CM (thumbnail)
price: $110
Late Summer 2018

A sharp scepter of zoned Amethyst from the Urals. There are what looks like two tiny stems on this crystal , but there is really just one with an ingrown second crystal. In very good condition, ex William Hladysz collection, a choice thumbnail from this classic locality.
Galena Ps. Pyromorphite - classic
stock #13.1-412
Kautenbach, Traben-Trarbach, Hunsruck
Rhineland-Palatinate, Germany
7.1 x 6.2 x 4.6 CM (cabinet)
price: $650
Late Summer 2018

One of the most respected European classics are the Pyromorphites that were pseudomorphed by Galena from Kautenbach. This specimen has very sharp and distinct hexagonal crystals that in some cases are fully pseudomorphed to Galena and a few have a later regrowth of an outer layer of Pyromorphite. The crystals are well exposed and stand up above the matrix. Very clean damage wise, the crystals on this specimen are small but much more distinct than usual from this classic locale. Ex Seaman museum, most specimens of this sort we have handled had larger crystals but also far larger price tags, usually in the 4-8K range. This is a good example of this treasured classic that is affordable but still choice.
Richterite with Magnetite -Superb for locale
stock #0168-JM-2927
Langban (Langbanshyttan)
Varmland, Sweden
7.2 x 4.9 x 4 CM (cabinet)
price: $520
Late Summer 2018

A sizable and well crystalized red-brown Richterite from Langban that is outstanding for this classic locality. Ex John Marshall collection he obtained it in 1992. His collection card notes that he showed it to Carl Francis who said it was "considerably better than the two specimens at Harvard in the Langban case. I checked and it is" He also notes he felt it "equivalent to the specimen on display at the British Museum". All that said there are larger crystals known from several other locales, but this color and habit seem to be unique to Langban, all the other worldwide specimens are black, colorless or a light yellow. Langban minerals tend to be a bit ugly, or microscopic, this is actually a displayable, cabinet sized crystal specimen. Though not an ultra showy, pretty mineral, this is a significant and fine specimen. Crystals to 1.6 CM, there is some damage but also several complete crystals, the smallest are transparent.
