Witherite - fine US classic
stock #15.1-1060 CN-2017
Minerva #1 Mine, Cave-in-Rock, Hardin County
Illinois, United States
8.8 x 6.7 x 4.1 CM (cabinet)
price: $750


An excellent old time USA Witherite with great form from the Minerva #1 mine. Classic early 1960s vintage. Ex Dufoe and Noll collections, with fat barrel shape crystals showing well stepped striations on the edges. This specimen also has a good light yellow-orange color and is much more attractive than the more usual plain white. Alston Moor in England and the Minerva mine, (all long closed) produced all of the fine Witherites ever found. Fine pieces like this are now only available from older collections and getting very scarce. This is an especially choice piece, has great wet look luster and displays great from several angles.
Fluorite -rare locale
stock #16.1-424-CN3960
Gyrenspitz, Santis Massif
Appenzell-Innerrhoden, Switzerland
8.2 x 7. x 4.3 CM (cabinet)
price: $500


Ex Herbert Obodda, Charles Noll collections. A really nice, unusual Fluorite from a rare Swiss locale. The crystals are modified cubes with beveled edges and some face frosting. Unlike what is usually seen as Swiss Fluorite, the original labels give the locale as "Gyrenspitz, west of Santis". This is a significant landmark but In that location no such Fluorites are known. However the Santis Massif (Alpstein Massif) has produced Fluorite this habit and look in the past. In good condition overall, The blue color is especially strong in direct sunlight.
Scheelite on Quartz -classic European
stock #19.1-295
Cinovec, Krusne Hory Mts.
Usti nad Labem Region, Czech Republic
5.7 x 2.9 x 2.6 CM (cabinet)
price: $750


A rarely available habit of Scheelite in balls and masses of tiny crystals on a doubly terminated Quartz. This is a very old specimen from the area also known as Zinnwald (on German side of the border) in the Erzgebirge / Krusne Hory mountains. The Scheelite balls are up to 5mm and composed of masses of small crystals clustered together. With good magnification it can be seen that some of the crystals are elongated pseudo-octahedra. In fine condition the quartz is undamaged and iridescent in person. From an old Czech collection, this is the most esthetic example of this habit I have ever seen.
Rhodochrosite -Scalenohedral crystals
stock #12.1-273
Uchucchacua Mine, Oyon Province
Lima Department, Peru
4.2 x 4.1 x 2.8 CM (miniature)
price: $650
Spring 2019

Sizable doubly terminated Rhodochrosite crystals sitting on contrasting matrix. These are the "fat Scalenohedral" habit from Uchucchacua and are translucent to transparent with the largest crystal 2.1 CM. The presenting face of the specimen looks in very good undamaged condition but the crystals do have contacts and chipping on the backs and sides so this is not for perfectionists. Depending on the display angle this can look quite perfect however. The crystals have some faces showing complex striations but others are smooth and lustrous. A great value for the size, color and form.
Amethyst on Quartz -unusual scepters
stock #19.1-294
Karur
Tamil Nadu, India
3.3 x 3.2 x 1.6 CM (small miniature/ large thumbnail (toenail))
price: $280
Spring 2019

Two generations of Quartz with the later growth of Amethyst being unusual bent scepters. Excellent color and in fine condition the contrast with the white Quartz is excellent and the purple is nicely zoned, intense and lustrous. From the remarkable Amethyst discoveries in Karur, this has an especially delicate and eyecatching appeal but the real uniqueness is the unusual scepter form.
Topaz
stock #18-AX-12-226
Sherlova Gora, Adun-Cholon Range, Nerchinsk, Chitinskaya Oblast
Transbaikalia, Russia
3.1 x 2.7 x 2.8 CM (small miniature/ large thumbnail (toenail))
price: $220
Spring 2019

A single transparent Russian Topaz with a very light blue hue. Nice but not perfect, there are contacts on the back and a few small edge nicks but still displays very well. Russian Topaz from Sherlova Gora is a classic, the area was producing Topaz back into the early 1700 era. This has better clarity than typical for the locale.
Torbernite
stock #17.1-143
Musonoi Mine, Kolwezi, Western area
Katanga (Shaba), Democratic Republic of Congo (Zaire)
8 x 4.3 x 2.8 CM (cabinet)
price: $1650
Spring 2019

A big well crystallized plate of deep green Torbernite from the old finds at Musonoi. In fine condition, with individual crystals averaging over a Centimeter (up to 1.5CM). These top Congo specimens are from finds decades ago, these are already considered to be classics for the specie. Most of the crystals here are standing on edge with termination faces showing but a few are laying flat. The flat faces have a lighter green color and are a nice contrast to those showing darker edges.
Copper- arborescent and spinel twin crystals
stock #18AX-10-905
Santa Rita, Grant County
New Mexico, United States
8.5 x 2.4 x 1.9 CM (cabinet)
price: $350
Spring 2019

Chain-like stack of arborescent and spinel twin crystals from New Mexico. Ex collections of Buck Keller and William Hladysz, this has just a hint of matrix adhering, but is mostly a sculptural tower of Copper. No damage and with a nice patina, this is an older piece that predates the Chino mine find that became famous in 2001. This piece almost certainly came from the Chino mine zone too, but that is not recorded on the previous label and we do not like to attribute without certainty. The Chino is a huge pit that has now encompassed other smaller mines, so many details of locality have gotten lost over time. A very nice copper from anyplace.
