HOLD Arsenic -Native crystals in ball form
stock #HOLD 20.1-604
Akadani Mine, Shimo-Ajimi-mura, One-gun, Fukui City
Fukui Prefecture, Japan
1.3 x 1.2 x .9 CM (thumbnail)
price: $190
new year 2021

A ball or nodule of rhombohedral Arsenic crystals from this famed Japanese locality. In fine condition on all sides, this is not beautiful to many people but these balls are considered to be the world's best Arsenic crystals, loved by collectors of native element crystals. This specimen is a bit sharper than average, fairly sizable (the largest are only a few MM larger) and has a good color and luster, many are very dull or have a whitish coating.

Realgar - single crystal
stock #4.2-185
Shimen (Jiepiayu) Mine, Shimen County, Changde Prefecture
Hunan Province, China
2.2 x 1.1 x .6 CM (thumbnail)
price: $220
new year 2021

A bright red crystal that is translucent to transparent, well-formed and distinctly striated. This crystal was mined in 2003, it has been stored in the dark so is fresh and bright. A few small rough spots are to be mentioned but overall this is in fine shape, well-terminated and a choice thumbnail. When these were found they were certainly the best Realgars available at that time, and are still about as fine as can be seen. Of special note, these Hunan Realgars seemed to keep their color and luster better than specimens from other localities.

Bournonite
stock #6.2-892
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province, China
3.1 x 2.6 x 1.5 CM (small miniature/ large thumbnail (toenail))
price: $350
new year 2021

A super bright "gun metal" luster Bournonite crystal which is doubly terminated. Some of the faces are perfectly smooth mirror-like while other are striated. From the Yaogangxian Mine which had the reputation for providing more fine Bournonite than the rest of the world's localities together. Before these finds this was a rather rare and sought after specie. There seems to be no twinning on this crystal which is unusual for Bournonite which is almost always twinned. Displays well as seen, there are some small chips on the terminations and the back is contacted but not damaged. While not perfect this is far better than 99.9 percent of these, and the rough areas are not excessive. As a whole Bournonites are notoriously brittle and most often incomplete.

Rhodochrosite
stock #18.1-538
N Chwaning II Mine, Kalahari Manganese Filed
Northern Cape Province, South Africa
9 x 7.4 x 2.3 CM (cabinet)
price: $1850
new year 2021

An excellent cabinet sized Rhodochrosite that is of an unusual habit for N'Chwaning. Rhodo crystals fully cover the face of this large plate of Manganite matrix. From the display side just a sliver of the underlying black Manganite crystals can be seen. The hundreds of tiny sparkling Rhodochrosite crystals are sharp transparent scalenohedra most being free standing when seen under magnification. In excellent condition, there is no damage found by naked eye and under magnification only micro bruises on edges can be found with some difficulty. The sparkling luster and undulating surface make an attractive cabinet sized specimen from this famed mine. The color is not the intense red that some N'Chwaning Rhodos have but is a good red to pink-rose hue. This is also not a 5 figure specimen it is a very good value for a sizable, undamaged Rhodo from this famed, classic locale.

Hydrocerussite
stock #17.1-058
Tsumeb
Otjikoto Region, Namibia
3 x 2.6 x2.2 CM (thumbnail)
price: $950
new year 2021

A cluster of well-defined Hydrocerussite from Tsumeb. These are coatings and replacements of the original Cerussite so are technically pseudomorphs though there may be some un-altered Cerussite deep inside the crystals. In excellent condition the luster is a pearly to dull powdery-white that is typical of the specie. Although this is not typically a "pretty" mineral, the form of this piece is a very attractive presentation of a rather rare mineral. An excellent Tsumeb piece that is just small enough to be a legitimate thumbnail. In remarkable condition, all of the main free standing crystals are undamaged on all sides, this ranks as a competition grade specimen.

Barite on Rhodochrosite
stock #18-AX-27-255
Cerro Warihuyn - Miraflores, Huamalies Prov.
Huanuco Department, Peru
3.7 x 2.1 x 1.7 CM (miniature)
price: $90
new year 2021

Thin glass-clear undamaged Barite crystals on a minimal matrix of Rhodochrosite and tiny Barites. A very clean and attractive small miniature with no damage. The Cerro Warihuyn find of Barites is simply incredible, there have been many choice pieces in several habits and colors. This specimen is a very pale yellow-green hue in the Barites which are perfectly transparent and seem almost colorless in person. These Barites are still an excellent value for quality and esthetics at a reasonable cost.

Babingtonite on Prehnite
stock #8.1-229
Meigu, Liangshan prefecture
Sichuan Province, China
7.1 x 5.2 x 2.6 CM (cabinet)
price: $680
new year 2021

Blocky, well-defined Babingtonite crystals perched on a contrasting green Prehnite. In fine condition as seen, the Babingtonites have a mixed luster, some faces and areas are slightly matte while others are more shiny. A few years ago this find produced a treasure trove of Babingtonites, the best and largest ever seen. The source seems to have been finished and these are now becoming scarce. The better pieces have the botryoidal green Prehnite matrix like this one.

Proustite - Ruby Silver crystals
stock #12.1-248
Imiter Mine, Imiter Mining Dist., Tinghir Province
DrĂ¢a-Tafilalet Region, Morocco
5.7 x 3.8 x 2.8 CM (cabinet)
price: $3300
new year 2021

A fine and esthetic specimen of nearly pure dark red Proustite in distinct crystals. Proustite is a true mineral lover's specie, the most desirable and rare of the "Ruby Silvers". Good specimens are prized and great ones are very highly valued. This is an excellent piece very fine for the locality which is one of the small number of sources for great specimens worldwide. This displays well in several orientations, it is crystallized on nearly every surface. Incredible under magnification too, with good lighting the Proustite is a brilliant ruby red and translucent. In excellent condition damage-wise, which is also rare for this delicate mineral. Several different habits are present, some seem to be twinned and the smallest crystals are clustered in rosettes and balls, the larger crystals are more distinct and somewhat separated. Super choice.
