Spangolite with Brochantite, Barite etc
stock #19.1-450
Blanchard Mine, Bingham, Hansonburg District, Socorro County
New Mexico, United States
8.2 x 6.3 x 2.7 CM (cabinet)
price: $140
Spring 2020

A complex specimen with a mix of bright blue Spangolite crystals in several patches mixed with Brochantites. The Spangolites are sharp and gemmy under good magnification, the matrix is quite colorful and more rich than typical from this great USA locality. Typically Spangolite is a micro mineral in most collections, this has enough good coverage to be visible by naked eye but certainly far more beautiful under magnification.
Rhodochrosite with Fluorite, Quartz etc
stock #13.1-136
Mine X, Mt Bress, Alma, Park County
Colorado, United States
11 x 7.1 x 3.2 CM (cabinet)
price: $1450
Spring 2020

A large plate of complex Fluorites crystals mixed with multiple minerals including Rhodochrosite Rhombs, Sphalerite, Quartz and misc Sulphides. The Fluorites are mostly a pale purple to almost colorless but a few smaller crystals have a distinct pink color caused by being formed on top of Rhodochrosite. Nearly all the crystals on this plate are lightly frosted and have a slightly "melted" look. This locality is located on the same mountain as the famed Sweet Home and Detroit City Mines. This locality is a small propect with minimal devolopment has been worked for specimens by a small crew for a few weeks each year. They choose to not name or provide exact location of the site to protect it. The Fluorites are clearly different in habit from most that come from the mountain and the overall esthetics of this piece are quite choice.
Chrysocolla Pseudo after Malachite after Azurite
stock #20-FC-025-(9121)
Whim Creek Copper Mine, Whim Creek, Roebourne Shire
Western Australia, Australia
6.8 x 5.2 x 4.2 CM (cabinet)
price: $420
Spring 2020

A super example of this classic Pseudomorph with excellent sharp form and intense blue-green color. The Chrysocolla has completely replaced the Malachite which had replaced rosettes of Azurite. These rosettes are perfectly preserved. As a bonus the matrix on this is heavily sprinkled with small, gem clear Wulfenite crystals. The last find of this habit was in 1985, the mine is long closed and no more are to be had. These Chrysocolla rosettes have excellent sharp detail, waxy luster and the incredible color. Choice.
Witherite on Fluorite
stock #20.1-083
Minerva #1 Mine, Cave-in-Rock, Hardin County
Illinois, United States
2.8 x 2.6 x 1.8 CM (thumbnail)
price: $140
Spring 2020

A complete ivory colored Witherite crystal sitting on a blue crystalline Fluorite showing classic form. From the famed Minerva #1 Mine, this is a well formed thumbnail specimen in very good condition. The faces of the Witherite have the characteristic tiny stepped structures that are so definitive for this locality.
Chrysoprase (nickle rich Chalcedony)
stock #20.1-107
Murramunda Community, Meekatharra Shire
Western Australia, Australia
8.2 x 5 x 2.4 CM (cabinet)
price: $85
Spring 2020

A very pure seam of good, dense green Chrysoprase with excellent translucency. Nearly all gem grade weighing over 96 Grams. From an older collection a 1966 vintage chunk.
Brazilianite -gem crystals, classic locale
stock #20-FC-064 (9173)
Conselheiro Pena, Doce Valley
Minas Gerais, Brazil
5.2 x 4.3 x 3.3 CM (small cabinet/large miniature)
price: $580
Spring 2020

A cluster of thick lustrous gem grade Brazilianites from the unusual locality of Conselheiro Pena. In fine condition as seen, only one small edge chip can be found which is not visible on any display angle. The two famed Brazilian localities (Telerio and Corregio Frio both in Linopolis) have a distinctly different look, color and habit from each other and from the less common Conselhiero Pena specimens. This piece has a small amount of matrix but is almost a complete floater. Choice and not often available,
Epidote with Albite
stock #20.1-108
Amis Gorge, Brandburg Complex, Daures
Erongo Region, Namibia
6.8 x 4.8 x 3 CM (cabinet)
price: $330
Spring 2020

Sharp dark green free standing Epidote mixed with contrasting Feldspar (Albite) crystals. From a small find made almost 20 years ago, this is far above average and displays well from any angle. The condition of the crystals is very fine. Unlike any other Epidotes from Namibia and even quite unlike most any location anyplace else.
Malachite PS after Copper, ex Bosch, Smithsonian
stock #15.1-947-(SM2855)
Tsumeb
Otjikoto Region, Namibia
5.7 x 3.6 x 2.5 CM (cabinet)
price: $600
Spring 2020

A super Pseudomorph with an outstanding, long provenance from the early years at Tsumeb. Radiating flower like structure that seems to be fully replaced by Malachite. Close to 100 percent Malachite, there is just a sliver of matrix on the base. An unusual form, as most Malachite Pseudos are clearly replacements of Azurite but this seems to be a replacement of a native copper structure. The bottom or underside has been sawn to make a flat spot so this sits perfectly on display. From the famed Carl Bosch collection (1874-1940) with his handwritten label and "code" to the Smithsonian institution and Charles M Noll, this has belonged in several major collections. The Bosch label code is described in the Mineralogical record, and if I can read this writing correctly it was obtained on July 17,1913 for 300 marks, a costly piece at that time. This is also a quite early specimen as the mine would not yet have reached level 6 at that date (it would eventually reach level 46) and this piece would have been found well before that date. There are relatively few specimens preserved from the earliest discoveries at the worlds greatest mineral locality. This is one.
