Halite and Tolbachite
stock #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.

SOLD Halite with Tolbachite - stacked and hoppered cubic crystals
stock #SOLD 21.1-183
Polkowice-Sieroszowice Mine, Glogow County
Lower Silesian Voivodeship, Poland
6.3 x 3.8 x 3.4 CM (cabinet)
price: $0


Amazing geometric form on this Halite from the recent find at Polkowice (Poland). The crystals are in perfect condition, sharply formed with stepped hoppering that looks great from all sides. No damage, the color is in part from Tolbachite inclusions, an uncommon simple Copper Chloride. A very esthetic example and a textbook perfect specimen. of stacked, hoppered cubes, a very elegant salt!

Gypsum (selenite) with Paratacamite
stock #21.1-180
Rudna mine, Lubin, Legnica
Lower Silesian Voivodeship, Poland
8.7 x 6.5 x 3.2 CM (cabinet)
price: $640


A very esthetic and unusual specimen from the remarkable finds at the Rudna Mine. A radiating spray of sharp, transparent bladed crystals of Gypsum are on a green matrix that has been determined to be in part Paratacamite. In excellent condition, many of the blades show fishtail terminations indicating that most are twinned. A fine example from recent discoveries, this can be shipped but we can also deliver to any of the major mineral shows that we attend.

SOLD Halite and Tolbachite - hoppered crystals
stock #SOLD 21.1-185
Polkowice-Sieroszowice Mine, Glogow County
Lower Silesian Voivodeship, Poland
5.2 x 3.6 x 1.8 CM (small cabinet/ large miniature)
price: $0
Late Summer 2021

Impressive structure and textbook form on these hoppered Halite crystals from the remarkable finds at Polkowice (Poland). The Halite is colored green by the rare mineral Tolbachite and also has inclusions we are told of some Bitumen, Sulphur and Covellite. Inclusions aside these are amazing in form and well-presented as sharp, undamaged modified cubes that show the incredible natural structure perfectly. This is from a fairly recent find that we consider to be one of the best in the mineral world, with great esthetics and an excellent value.

Selenite with Herbertsmithite inclusions
stock #16.1-535
Rudna mine, Lubin, Legnica
Lower Silesia, Poland
8.3 x 7.8 x 7.3 CM (cabinet)
price: $1150


A well crystalized cluster of Gypsum (Selenite) with rich green inclusions and encrustations of the rare mineral Herbertsmithite. This find has produced what are certainly the most esthetic examples of this specie as Herbertsmithite is not usually a "display" grade mineral. Recently Herbersmithite was found to have unique properties of changeable magnetism and with quantum spin properties. This was picked up in some of the popular media and somewhat exaggerated as news, even being called a "new form of matter". There was a brief period where tiny crumbs were being sold for high prices. Despite the inaccurate hype this is a remarkable mineral and on this specimen it is actually attractive.

Celestite on Sulphur
stock #AX-10-1016
Machow Mine, Tarnobrzeg
Podkarpackie, Poland
9.3 x 6.6 x 4.9 CM (cabinet)
price: $330
Post Tucson 2015

Bright and gemmy Celestite (Celestine) crystals are in radial sprays on vivid Sulphur crystals. In fine condition, the matrix is an open pocket that has protected the delicate crystals inside. Similar to old specimens from Sicily, the luster and sparkle of this specimen is equal to those.
