Cassiterite on Quartz
stock #18AX-12-417
Amo Mine, Ximeng
Yunnan, China
3.8 x3.4 x 2.2 CM (miniature)
price: $440
Late Summer 2018

Cassiterites in gemmy crystals with brilliant luster and sharp form. The Amo mine in Ximeng county (Yunnan, China) produced a few spectacular Cassiterites. They were immediately prized and have almost disappeared. Unlike from any other location, these had a unique, recognizable style that could be very esthetic. This fine example is sharp, well formed, nicely perched on a cluster of quartz crystals that have some green inclusions as a bonus. In great condition there is contacting only on the back side not in view. In some photos what may look like damage is internal reflections inside the Cassiterites. Much better in person.
Calcite (Pineapple) on Fluorite
stock #6.2-306
Shangbao Pyrite Mine, Leiyang
Hunan Province, China
3.7 x 3.2 x 2.0 CM (miniature)
price: $290
Late Summer 2018

Almost 20 years ago the Shangbao mine in China encountered some pockets of "pineapple" look Calcites. The best of these were on contrasting Fluorite and had (to my eye anyway) great esthetic appeal. This is a small but perfect example of that find. The color, luster and habit are distinctive for these Calcites and unlike any others from anyplace. The Calcites are transparent and undamaged (a small contact is on the backside, but no damage). A fine small modern classic piece.
Ilvaite on Quartz
stock #18-AX-15-286
Huanggang Mine, Chifeng Prefecture, Hexigten Banner, Ulanhead League
Inner Mongolia Region, China
7 x 4.9 x 4.5 CM (cabinet)
price: $360
Late Summer 2018

The Inner Mongolian region finds in the past few years re-defined how we look at Ilvaite, these were huge news in the mineral world. This specimen is sharp and quite lustrous, the Ilvaite is undamaged and sits on greenish quartz needles (likely included by Hedenbergite). Very esthetic (for a black mineral, this is exceptional) the form is textbook and the contrast with the matrix is choice. These better pieces are world class for the specie and still very affordable, a good time to add a good example before these inevitably disappear. .
Apatite (CaF) on Pericline
stock #13.1 -163
Anemzi Village, Midelt Province
Meknes-Tafilalet Region, Morocco
5.3 x 4 x 3.2 CM (small cabinet/large miniature)
price: $320
Late Summer 2018

The sort of gemmy Apatite that is sometimes called "asparagus stone". Set on a complex Feldspar matrix, there are a few small Apatites there as well. The main crystal is textbook sharp, transparent and depending on the lighting looks either lemon yellow or asparagus green. Close exam reveals what looks to be a repair, if so it is well done. Of course the price is adjusted for that. A choice display piece regardless the contrast is especially nice.
Lavendulan with Conichalcite etc.
stock #8AE-993
La Reconquistada, Pastrana, Mazzaron
Murcia, Spain
7.3 x 4.7 x 3.8 CM (cabinet)
price: $420
Late Summer 2018

A very rich specimen of several uncommon Copper species, most importantly Lavendulan. Also containing a sizable zone of Conichalcite, minor Azurite and what appears to be Barahenaite (not analyzed). The Lavendulan is present in thick bands, crusts and small crystals of several habits. The Conichalcite is in translucent green globules covering one entire face. Lavendulan is a Phosphate and also an Arsenate, with the complex formula ofNaCaCu5(AsO4)4Cl·5H2O. Not often seen on the mineral market except in small blebs or micromounts.
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.
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.
