HOLD Halite and Tolbachite
stock #HOLD 21.1-184
Polkowice-Sieroszowice Mine, Glogow County
Lower Silesian Voivodeship, Poland
6.9 x 4.8 x 3.8 CM (cabinet)
price: $330


Incredible, perfect hoppered cubic crystals of Halite are stacked in an eptaxial cluster. From the recent finds at Polkowice (Poland) this a a textbook example of this form. The crystals have a distinct green color and by analysis this is due to the very rare mineral Tolbachite which is a Copper Chloride not often seen in collections. I consider the better examples of these to be super esthetic and this specimen is excellent by any standard.

Pyromorphite - vintage classic
stock #AX-35-145
Wheatley Mines, Pheonixville
Pennsylvania, United States
5.9 x 3.3 x 2.3 CM (cabinet)
price: $390
New Year 22

A small cabinet of bright drusy Pyromorphite from the famed Wheatley mine (Pennsylvania, USA). The matrix is typical for the mine, the crystals have the dark olive green color that is distinctive to the locale. This specimen is from the collection of WG Levison but unfortunately does not retain any of his labels. This dates to the 1890 era in the collection but the specimen is likely much older, as the mine had closed in the 1860's. The the crystal coverage is quite rich even though the individual crystals are small. With magnification most of these are seen as transparent, sharp and very lustrous.

Millerite on Galena - classic German
stock #15.1-537
Pfaffenberg Mine, Neudorf, Harzgerode, Harz Mts.
North Rhine-Westphalia, Germany
11.9 x 9.6 x 6.8 CM (cabinet)
price: $650
New Year 22

A large crystalline mass of Galena is host to several cavities filled with brassy Millerite needles. A fine old German specimen from the Pfaffenberg Mine which is best known as a classic source of Galena, and rarely of Millerite. A druse of Quartz adds some contrast and sparkle as well, but the real attraction is the nests of radiating Millerites on several faces of the matrix. This mine was operated for Iron and was a major operation by the mid 1800's, though mining in the zone can be traced as far back as 1400. This was operated until 1962, the Millerites from here are uncommon on the market and are German classics.

Grossular - rose-pink Garnet
stock #21.1-173
Cerro Azul, Sierra de Cruces
Coahuila, Mexico
6.8 x 5.7 x 4.1 CM (cabinet)
price: $290
New Year 22

From a relatively new find (2020-21) by Denis Beals; these are larger rose Garnets from an area of the Sierra de las Cruces. This site has produced a few relatively large Garnets embedded in a hard Rhyolite matrix. Noticeably different in habit and look from the previous finds in this region, this piece is an excellent example. A cluster of two main intergrown Grossular crystals show good luster and contrast well with the matrix. Some contacting is noted, there are geometric imprints of other Garnets and some rougher faces, as was true of every piece we examined from the find. Nevertheless, while this is not a piece for perfectionists it is still a fine and colorful Mexican Garnet unlike anything else from the region.

Sturmanite - large stacked crystals
stock #21.1-455
N Chwaning Mine, Kalahari Fields, Kuruman
Northern Cape Province, South Africa
7.4 x 4.7 x 3 CM (cabinet)
price: $1950
New Year 22

Very large and welL-defined cluster of Sturmanite crystals with a patina that in some light shows a iridescent color play. Not long ago Sturmanite was a very rare mineral and such huge crystals were unheard of. The great finds from South Africa changed that, but this size and level of quality is still very uncommon. Very impressive in person and now very hard to get.

Wulfenite - USA Classic
stock #21.1-522
Red Cloud Mine, Silver District, Trigo Mts, La Paz County
Arizona, United States
1.7 x 1.7 x .6 CM (thumbnail)
price: $280
New Year 22

Brilliant red single Wulfenite crystal perched on a small bit of matrix. In excellent condition, no chips or damage, the color and luster are both top. Classic specimen from the last mining of this iconic locality, just a nice, clean thumbnail that shows why this mine became a legend in the mineral world.

Cuprite - classic Tsumeb
stock #16.1-470-(CN5501)
Tsumeb
Otjikoto Region, Namibia
5.1 x 4.2 x 3.2 CM (small cabinet/ large miniature)
price: $750
New Year 22

A rich array of stacked, aligned crystals of Cuprite from Tsumeb. Cuprite is not rare from this mine but this is an unusually esthetic and sizable cluster of crystals, the largest to almost 1 CM. Under average lighting this looks very dark, almost black, but with strong lighting the more red color is seen. Most of the crystals are translucent and can glow with a good backlight. In excellent condition the matrix hosts a few isolated crystals but the main pure cluster of Cuprite is a full 5 CM across. The epitaxial arrangement of the Cuprite (most of these are Octahedra and aligned) is also very evident in person. A much better than usual Cuprite from Tsumeb, this is ex Charles M. Noll collection.

Jouravskite
stock #21.1-377
N Chwaning Mine, Kalahari Fields, Kuruman
Northern Cape Province, South Africa
3.6 x 1.8 x 1.4 CM (small miniature/ large thumbnail (toenail))
price: $360
New Year 22

Bright yellow crystals of the rare mineral Jourvaskite on matrix. Although small, up to just 1.5mm, these crystals are huge for the specie. Vivid color and in excellent condition. The backside of the matrix is massive Manganite with a thin layer of Rhodochrosite underlying the Jouravskite, Quartz and what seems to be Xontolite. A choice and pretty specimen of a rare mineral; ex Terry Szenics collection.
