Barite -rosette form
stock #18-AX-12-343
Quarry near Baixa Prison, Joao Pessoa
Paraiba, Brazil
4.3 x 4.3 x 3.2 CM (miniature)
price: $160


Transparent to translucent Barite crystals in a distinct Rosette form. From an unusual locality in Brazil, the crystals have well-defined phantoms as well. In fine condition as seen, there is minimal matrix. Ex William Hladysz collection, an almost never seen Barite from Brazil that is very esthetic.
Mimetite on Wulfenite
stock #15.1-857
Rowley Mine, (Reliance Mine), Theba, Painted Rock District
Arizona, United States
1.7 x 1.2 x .7 CM (thumbnail)
price: $325
Late Summer 2018

Clear widow-pane Wulfenite crystals are the matrix for Mimetite in bright red balls. A small but striking thumbnail from Rowley mine collected during the final efforts there before it was shut down. Delicate and with brilliant color there were not many found like this, and the habit is unique to this one occurrence.
Pyromorphite/ Vanadinite - Classic locale, Ex. Bally
stock #0653-JM-4225
Berezovsk Mine, Ekaterinburg, Sverdlovskaya Oblast, Middle Urals
Urals Region, Russia
7.6 x 3.8 x 3.3 CM (cabinet)
price: $380
Late Summer 2018

A choice historic piece from the classic Berezovoskii, Ekaterinburg an early gold mine and the type locale for Crocoite. See the Mineralogical record 2016 Vol 47 #4 for a fine detailed article. This is clearly a Pyromorphite and also is labeled as having (and looks like) Vanadinite. Vanadinite is not listed as a specie from here, however this may all be Pyromorphite. This was in the Bally Museum, later with Alain Martaud and last in the John Marshall collection. Old labels are included. The specimen is crystallized on every side, in fine condition. Most of the Pyromorphite I have seen from this famed old Gold mine area are mere green smudges, but this is much more substantial.
Barite included by Realgar (classic)
stock #14,1-107
Baia Sprie
Maramures, Romania
7.2 x 6 x 2.9 CM (cabinet)
price: $1850
Late Summer 2018

For many collectors, the most desirable Barites (Baryte) are the rare, classic Romanian specimens colored bright red by Included Realgar. This is a choice old specimen in excellent condition with delicate orange-red Barites on contrasting matrix. The crystals show sheaf-like bundles and rosettes well separated from the matrix and free standing. Crystallized on both sides this has very strong display impact. Almost impossible to find today even average specimens have become very expensive.
Copper Pseudomorph after Aragonite
stock #17.1-179
Corocoro, Pacajes Province
La Paz, Bolivia
3.4 x 2.2 x 2.7 CM (miniature)
price: $490
Late Summer 2018

Sharp replacement of hexagonal Aragonite crystals by native copper. Excellent form, complete on all sides and with classic hexagonal prisms. Slightly hoppered on flat faces, this is formed of two textbook prisms that intersect on one narrow edge. Usually these pseudos are rather crude, it is very special when such sharp detail is preserved.
Lazurite pseudo after Sodalite
stock #15.1-336
Fayzabad, Koksha Valley, Khash-Kuran Wa Munjan District
Badakshan, Afghanistan
4.8 x 3.3 x 2.7 CM (miniature)
price: $700
Late Summer 2018

A brilliant blue crystal of Lazurite nicely perched on a Calcite matrix. This is quite a fine Lazurite but it is in fact much less common, it is a partial pseudomorph of a Sodalite crystal. Both minerals are known to pseudomorph each other but can have similar crystal shapes so it is hard to detect. On this crystal there is some small zones where the brilliant blue is only partly covering the whitish to more pale blue interior. The core of the crystal can be seen and is still Sodalite, This is vividly Fluorescent in those spots but the exterior blue Lazulite has no response. The crystal is up to 2.7 CM across and contrasts perfectly with the matrix. A choice crystal and intense blue pseudo.
Cinnabar -elongated crystals with Dolomite, Quartz
stock #13.1-047
Tongren Mine, Wanshan District, Tongren Prefecture
Guizhou, China
8 x 5.1 x 2.9 CM (cabinet)
price: $690
Late Summer 2018

Free standing elongated crystals of Cinnabar in a well protected vug lined with small crystals of Quartz and Dolomite. Excellent bright red color and very translucent. The largest crystals have sharp terminations with distinct re-entrant notches, so they are in fact twins. Slender elongated crystals like these are much rarer than the blocky type and since the mines are closed for a few years, any good quality Cinnabar is now very scarce. In fine condition and with bright luster, Chinese Cinnabar crystals have always been respected and desired as the worlds best for the specie.
Quartz - Pseudocubic form
stock # 18.1- 102 A
Artesia, Eddy County
New Mexico, United States
2.6 x 2 x 1.8 CM (thumbnail)
price: $500
Spring update

A sharp and complete crystal of the very rare "pseudocubic" habit Quartz, which is also very large for the form. The form is more correctly a skewed cube with overdeveloped rhombohedral faces that are not at 90 degrees but can look like it from several angles. No damage. This was incorrectly attributed to a small Arizona find but it is now confirmed as a very choice New Mexican specimen.
