Mimetite and Barite
Chah Milleh Mine, Anarak Dist., Nain Co.
4.1 x 3.1 x 2.2 CM (miniature)
Bright orange crusts and balls of Mimetite in a nearly pure mass with no matrix. One edge has a cluster of transparent Barite crystals with white edging on flat blades. A fine undamaged specimen that has good color and form. The Chah Milleh mine produced a few of these fine Mimetites three years ago, it has not since.
3.1 x 2.7 x 2.4 CM (small miniature/ large thumbnail (toenail))
A choice early Azurite from Tsumeb formerly in the Johannson collection obtained in trade with Harvard before 1933. Thick rectangular blades in a mass on minimal matrix. Excellent luster and a somewhat unusual form, this has some chipping and some rehealed areas that can hidden by angle of display. The edge modifications and faces on this Azurite are very unusual for Tsumeb and in fact for any locality.
For the Ahumada mine (los Lamentos) this is a huge crystal of Anglesite for that mine, and is partly altered to Cerussite on the surface. Ex Johansson collection, this is an older piece, pre 1940. In very good condition and well terminated as seen, (crudely doubly terminated) the crystal has retained the textbook form of the Anglesite. Los Lamentos is world famed for fine Wulfenite, Vanadinite and Descloisite but other Lead secondaries have been found over the long history of the mine. Large crystals of Anglesite are usually up to 2 CM, but at 4.3 CM this is one of the largest I have ever seen. A choice and substantial Mexican classic.
Rosasite on Smithsonite with Calcite
Silver Bill Mine, Gleason, Dragoon Mts. Cochise County
4.3 x 3.8 x 2.2 CM (miniature)
Spheres of blue Rosasite scattered on Smithsonite and some Calcite. A good locality piece that is especially fine under magnification. The Silver Bill mine has a long history but is not very well known outside of Arizona. It has been a source of Wulfenite and other species as well as Rosasite.
A very fine, large block of matrix well crystalized on the two largest sides with lustrous blue Lazulite crystals. One side has the association of many transparent golden Siderite crystals and clear Quartz, the other side has more Wardite crystals also very clear. with colorless to blue green hues. The rare phosphate deposits at Rapid creek are famed for the incredible Lazulite and this is a very fine showy example. The overall condition is excellent, strong magnification shows just a few chipped crystals in one area but by naked eye it is perfect. Especially under strong lighting the color is an intense electric blue, and the sparkling luster is brilliant. The Rapid creek Lazulltes are not the largest but they are the finest, sharpest, most colorful worldwide, and are especially gemmy. An excellent display cabinet specimen.
Sphalerite -gemmy crystals
ZCA Corp./Hyatt Mine, Talcville, St. Lawrence Co.
2.4 x 2 x 1.8 (thumbnail)
Late Summer 2018
A super thumbnail of fine gem clear Sphalerites that came from Talcville decades ago. in excellent condition, this looks great from several angles and the luster is brilliant. A more modern USA classic these do not turn up very often. The Sphalerites stand out well from the dark matrix making a nice three-dimensional presentation.
Mina Ojuela, Mapimi
2.7 x 2 x 19 CM (thumbnail)
Late Summer 2018
An especially esthetic, sharp flowerlike burst of Manganoan (purple-magenta tipped) Adamite. This cluster rests on a solid gossan matrix like an icecream cone, and has excellent proportions. Fine luster and condition, in person a little more purple color is noted. Ojuela produced only a few of these that looked this good, a quality, competitive thumbnail. Collected pre 2000, perhaps much older.
Spodumene Var. Hiddenite -Classic
Stony Point, Alexander County
2.4 x 1.7 x .5 CM (thumbnail)
Late Summer 2018
A superb, intense color USA Hiddenite, from the collection of Warren Johannson which he obtained in trade from Harvard in in 1934. Unlike the typical slender crystals, this is a wide and stout example, a complete floater with the top quality brilliant "Emerald" green color, weighing 17.7 ct. Complete all around, complexly etched and doubly terminated, this is a killer thumbnail that is hard to fully appreciate in photos. The Alexander County NC Hiddenites are of course the "real" thing, unlike green Spodumene from Pakistan or Brazil these do not fade, are not irradiated and can have this rare unique color unlike any others. Gem clear and lustrous, a true Hiddenite (the town of Hiddenite is about 6 KM from Stony point, the zone where this was first discovered in 1879). Classic specimen from a classic locale of a rare quality.
