Cuprite on Plancheite, Chrysocolla and Malachite
stock #Alec 11-048
Mupine Mine, Kolowezi District
Katanga (Shaba), Democratic Republic of Congo (Zaire)
4.8 x 3.2 CM (miniature)
price: $850
Spring 2014

A very fine, sharp and esthetic specimen! These Cuprites came out over 20 years ago, there have really been none since. Unlike any of the more recent Russian Cuprites, these Congo Piees are now classics. Most were damaged or at least chipped, so pristine pieces were rare then and unavailable now. This one is especially elegant, it has a sharp and sizable main crystal perched perfectly on the contrasting matrix. In exceptional condition. This was not photographed with a backlight, so it looks as it would in a normal display, HOWEVER these are a rich ruby red color with careful lighting. Better in person!
Amethyst Scepters
stock #13.1-267
Little Giant Basin, San Juan County
Colorado, United States
6 x 4.5 CM (cabinet)
price: $550
Spring 2014

A very nicely formed piece with light purple tips all arranged in a row. This came from an older collection with labels stating (unbelivably) it is from Creede District, Colorado. Checking this with Colorado specialists confirms that this is actually a fine Little Giant Basin piece from San Juan County, Colorado. Overall in great shape, only slicht chips noted with a careful exam and not easily seen on display. Most of these scepters were found as separated singles, such clusters are rare.
Torbernite (complex crystal aggregates)
stock #A7-038-1339
Les Bois-Noirs, Loire
Rhone-Alpes, France
4.1 x 2.9 CM (miniature)
price: $350
Spring 2014

Brilliant bright Green crystals of several habits densely cluster on the top and sides of this matrix. From the Larry White collection, this is an older piece and in pristine condition. Not just a "locality" specimen, this is very esthetic and not often available.
SOLD Adamite (manganoan)
stock #SOLD 10.1-175
Mina Ojuela, Mapimi
Durango, Mexico
3.4 x 3.1 CM (small miniature/ large thumbnail (toenail))
price: $0
Spring 2014

The worlds best Adamites have come from Mina Ojuela, there have been so many that it is hard to find specimens that stand out. This is a very esthetic "toenail" sided piece with multi-color crystals, glassy luster and in fine condition. The mix of the yellowish, pink and purple hues in the crystals helps make this a very nice display piece. The largest crystal is 1.8 CM tall which is quite sizable for the specie.
Cinnabar (twinned crystals on Quartz and Calcite)
stock #6.2-640
Yanwuping Mine, Wanshan, Tongren
Guizhou, China
5.3 x 3.8 CM (small cabinet/ large miniature)
price: $290
Spring 2014

A textbook example of twinning is well displayed on this unusually attractive specimen. The matrix is also unusual and contrast well with the Cinnabar. This comes from a small, little known mine in the Tongren area of Guizoh Province. Just 30 years ago such specimens were only known in the West from collections built well before 1909, they were legendary and unavailable. Even today with excellent sources this quality is far better than what is normally on the market. Far better in person.
Arsenopyrite with Hedenbergite and Lollingite
stock #Alec-14-312
Huanggang Mine, Chifeng Prefecture, Hexigten Banner, Ulanhead League
Inner Mongolia Region, China
6.2 x 2.7 CM (cabinet)
price: $575
Spring 2014

Simply a very esthetic and bright shiny Arsenopyrite with first rate presentation. EX Irv Brown Collection. Good Huanggang minerals are now the most sought after Chinese specimens and this is a particularly well composed piece in excellent condition. Displays well from all angles.
Grossular (pink stacked crystals with micro Diopside)
stock #17.AL-501
Jeffrey Mine, Asbestos
Quebec, Canada
4.2 x 4 CM (miniature)
price: $245
Spring 2014

Grossular from the defunct Jeffrey mine is considered some of the worlds best, especially in the rarer colors. Pink is particularly desirable and quite uncommon. This specimen is especially bright, lustrous and has strong color. The small crystals are well formed, sharp and distinctly aligned in sheets and plates giving a nice overall arrangement. Displays well from several angles, most crystals are perfect with only a few damaged ones found with magnification, and not at all noticable. A very good value.
Brazilianite (older USA specimen)
stock #A10-1059
GE Smith Mine (Chandler's Mills) Newport, Sullivan County
New Hampshire, United States
5.8 x 3.9 CM (small cabinet/ large miniature)
price: $80
Spring 2014

Brazilianite crystals of any size from outside Brazil are rare. This New Hampshire USA specimen has a main crystal prism 1.3 CM across and many smaller in a cluster that is about 3.2 CM across. For a non Brazilian piece this is darned good speciemn of this unusual phosphate. Collected in the late 60's these are not seen very often anymore.
