Boltwoodite on Calcite
stock #19.1-297
Goanikontes Claim, Goanikontes, Arandis
Erongo Region, Namibia
10 x 8.4 x 5.2 CM (cabinet)
price: $1650


An especially choice large specimen of Boltwoodite on a contrasting dark brown druse of Calcite. Protected by this shallow pocket, the radiating clusters of sharp bright yellow to orange needles are in excellent condition as seen. The radiating areas are about 1 CM across which is larger than typical as well. Special arrangements are needed in shipping or this can be delivered in person at a mineral show. Fine overall esthetics and rich density of Boltwoodite on matrix make this a top specimen for the specie.
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.
Proustite on Quartz - Classic
stock #18-AX-12-209
Freiberg
Saxony, Germany
2.2 x 1.8 x 1.7 (thumbnail)
price: $200


Deep red small crystals of Proustite scattered on a complex mix of tiny yellowish Quartz crystals. A nice thumbnail of a "noble" Silver mineral that has several different habits showing. With magnification some broken areas are noted which is typical for most Proustites but all in all this is a cute and fairly rich specimen from a classic locale. Ex. Wm. Hladysz collection, he acquired this in 2003.
Cassiterite, Aquamarine and Muscovite
stock #18-AX-15-161-C273
Mt. Xuebaoding, Pingwu Co., Mianyang Pref.
Sichuan, China
8.8 x 4.3 x 3.1 CM (cabinet)
price: $1100


Exceptionally lustrous and choice specimen of Cassiterite crystals clustered with light blue Beryl (Aquamarine) and set off by well crystalized Muscovite. Ex Shields Flynn collection, this is an older Mt. Xuebaoding specimen that is unlike any of the later finds and is especially esthetic in person. In excellent condition as seen, the display face is in perfect condition the only damage is on the outside edges where this was removed. The bright glassy luster of the Cassiterites is hard to capture in photos it is really brilliant in person.
Realgar -doubly terminated crystals
stock #6.2-838
Shimen (Jiepiayu) Mine, Shimen County, Changde Prefecture
Hunan Province, China
4.5 x 3.3 x 1.3 CM (miniature)
price: $380


Sharp, bright gemmy red Realgar with intense color. This specimen has minimal matrix and has not been displayed in bright light so it is still very impressive. This was mined in 2005 so it has held its color very well. Minimal bruises on a few edges are not easily seen by naked eye and the main crystals are in fine shape. The Shimen mine was at one time a prolific source of super (maybe the worlds best) Realgars, but it is no longer operating. The backside of the specimen has just a hint of matrix on it and is contacted where it was attached but the rest is very well crystallized and nearly all crystals show double terminations. Unusually fine for one of these.
Grossular green-core "frog egg"
stock #18 -AX-392
Jeffrey Mine, Asbestos
Quebec, Canada
1.7 x 1.6 x 1.4 CM (thumbnail)
price: $290


A small thumbnail showing intense green core clear Grossular crystals. This habit was often called "frog egg" and was only found at the Jeffrey Mine, and only rarely. Ex Larry White collection, he obtained this in 1975, at that time it was labeled as a Uvarovite, a common error when these were first found. This specimen has super sharp, gemmy crystals with a small bit of matrix. The luster is bright glassy, transparent and is over all in fine condition. Looks especially great under magnification where small details can pop out. These have become very hard to get and it seems there will never be more. Small but very eye catching.
