Ludlamite with Vivianite
Blackbird Mine, Lemhi County
6.3 x 4.3 x 1.7 CM (cabinet)
The Blackbird mine was a small Cobalt operation that in the 1950-1960s occasionally produced well crystallized Ludlamites. Sometimes with Vivianites, these were by far best of the specie found in the US, and some can be compared to good Bolivian material. This is a good small cabinet with both species in well developed crystals. Very hard to find anything larger than a thumbnail now, this is an early 1960 vintage piece ex Charles Noll collection.
Boltwoodite on Calcite
Goanikontes Claim, Goanikontes, Arandis
10 x 8.4 x 5.2 CM (cabinet)
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
8.8 x 6.7 x 4.1 CM (cabinet)
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
Gyrenspitz, Santis Massif
8.2 x 7. x 4.3 CM (cabinet)
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.
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.
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.
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.
Sherlova Gora, Adun-Cholon Range, Nerchinsk, Chitinskaya Oblast
3.1 x 2.7 x 2.8 CM (small miniature/ large thumbnail (toenail))
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.
