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.
Pentahydroborite with Wurtzite
stock #18-AX-32-221
Shijiangshan Mine, Linxi, Ulanhad League
Inner Mongolia Region, China
3.8 x 2.6 x 1.7 CM (small miniature)
price: $140


Pentahydroborite is a rare Hydrous Calcium Borate, that has only been found a few times in very few widely scattered small deposits. The most recent finds were in the 1990s in Japan and in a single pocket in 2014 in Inner Mongolia. There have been no more since. This piece is well crystallized and is in excellent undamaged condition from Inner Mongolia. There is a little Wurtzite that adds some contrast as well. The crystals are in two different habits and some are in leafy groupings.
Bournonite, Quartz and Pyrite
stock #18-AX-10-906
Pachapaqui District, Bolognesi Province
Ancash Department, Peru
7.2 x 5.4 x 5.2 CM (cabinet)
price: $280
Late Summer 2018

Two-sided specimen with excellent sharp Bournonites on both sides. All the Bournonites show bright silver luster and twinning that in some crystals has the classic cogswheel habit. The side I consider the "front" or better display side has two main Bournonites that are perfectly formed and undamaged, set off by golden Pyrite and milky Quartz crystals. The "back" side has more nice Bournonites but there is some damage and contacts, (that is why it is the back of course). A few years ago matrix Bournonites of this quality were very rare and expensive when available but both China and Peru then began to produce these and they became very affordable. Now both these sources are not producing.
