A superb classic thumbnail specimen from the famed Neudorf area, best known for world-class Galenas and rarely some great Bournonites. In flawless undamaged condition. These Bournonites are bright, lustrous metallic crystals on a matrix of sparkling white Quartz that is also the host for fine Siderite crystals. This can be displayed in several orientations, it is almost impossible to find a choice thumbnail like this from Neudorff today. A few earlier labels are included, this sort of specimen is certainly very old.
Amethyst - sceptered crystal
Piedra Parada, Las Vigas
4.7 x 3.2 x 2.2 CM (miniature)
New Year 22
A small, well-composed specimen of Amethyst perched on a contrasting matrix with a druse of greenish Epidote. From the prolific finds at Piedra Parada, the Amethyst is distinctly sceptered and in perfect condition. These Amethyst when they are perfect like this are one of the best current values in minerals. We hope the locality can continue to produce for a long while.
A rind of tiny, glassy Gordonite crystals on a Variscite nodule that has a tiny bit of Crandallite as well. From the type locality in Utah. This is the type locality for this specie found during the famed excavation project by Ed Over and Arthur Montgomery in the 1930's. The individual micro crystals are up to 1.5 MM in size, which is fairly large for the specie. These are both isolated, free standing and in radiating sprays. Remarkably the main cluster of crystals extends across 1.5 CM which makes this specimen an incredibly rich example, very fine for this rare specie.
Senarmontite - type locality
Djebel Hammimat Mine, Ain Babouche District
Oum el Bouaghi Province,
1.8 x 1.6 x 1.5 CM largest (thumbnail)
New Year 22
A pair of sharp and very large Senarmontite crystals with classic form from the type locality. This rare Antimony Oxide was found sporadically between 1850 to 1950 at this locality by the French Geological exploration group BRGM. These remain as the best and largest crystals of this specie. These crystals are far larger than average at this locale and are well-defined. Worldwide Senarmontite is found in just a few other Antimony deposits, usually as micro-sized octahedra not often much larger than 1-2MM. Very fine for the specie and not often available, Ex Paul Sainfeld and Tunisian Geological Service collections.
Epidote - Northeastern USA classic
VAG Mine, Lowell & Eden
5.1 x 1 x .9 CM (small cabinet/ large miniature)
New Year 22
A single sharp and glassy Epidote crystal with perfect termination from the famed VAG Mine, (aka Belvidere Mt./ "Eden Mills" Vermont), find made over 35 years ago. This zone produced several very fine crystals including the largest complete Epidotes ever found in the USA (and perhaps the world). This specimen is much smaller than the giants but has no repairs (the big ones were broken). Almost never available except in older collections, this is in perfect condition, partly transparent with well-defined striations.
A large and rich cabinet sized Pyromorphite on Coronadite from Broken Hill. A classic locality and a classic association from this iconic mine. The matrix is very three dimensional, a botryoidal black background for hundreds of very lustrous olive green Pyromorphites. Under the Coronadite is massive Galena and a little Cerussite that is not seen from the display side but adds a heft to the specimen. In exceptional condition, very hard to appreciate in photos but an excellent classic in person.
Glassy octahedral crystals of Spinel from the famed gem regions of Mogok in Myanmar. At first glance this looks almost black but under good light the color is a blue to purple-red color in zones and the crystals are transparent to translucent. In person the luster is brilliant and the condition is also very fine. These crystals have the typical rounded or melted look in some places but are very sharp on most edges. Much of the Spinel from Mogok is vividly fluorescent red, this is not, but under long wave is an unusual pale green. 60.45 grams overall there are a few areas of gem clarity but most is included. A nice and very unusual Mogok Spinel.
A large and rich specimen of this uncommon Turquoise variety from the St. Austell district where this was originally described from several mines. The Rashleighite is a botryoidal green covering much of the matrix. This is set off nicely by sparkling micro crystals of what seems to be very transparent Siderite. A sizable and colorful old Cornish specimen.
