SOLD Calcite included by Chalcotrichite - USA classic
stock #SOLD 20.1-907-(ZSCTR4098)
Campbell Shaft, Bisbee, Cochise County
Arizona, United States
8 x 5.9 x 5.7 CM (cabinet)
price: $0
Late Summer 2021

An excellent and very colorful example of a Calcite with blood-red Cuprite (variety Chalcotrichite) included in Calcite crystals. Calcites from Bisbee were sometimes included by Copper minerals, often Malachite, and colored by these inclusions. This is a sizable example of this quite rare and prized red Calcite from the Campbell shaft at Bisbee. There are cleaved crystals at the outer edges but the main red Calcites are in good condition overall. The matrix is a solid ore and has a few areas of micro Cuprites on it as well. The Calcite crystals are up to about 1 CM. Most Bisbee minerals seen in displays are green or blue, bright red specimens are uncommon and really stand out. These old Calcites are just about never available except from the breakup of old collections.

Conichalcite with Calcite
stock #21.1-177
Mina Ojuela, Mapimi
Durango, Mexico
7.4 x 5.6 x 3.7 CM (cabinet)
price: $850
Late Summer 2021

A fine and unusually esthetic Conichalcite from the mid 1970 finds at the legendary Mina Ojuela. This piece looks great on three sides, the Conichalcite forms vivid small green spheres some with clear sharp Calcite crystals. On one face of the specimen the Conichalcite balls have formed selectively over Goethite rods or "fingers". On another side the Calcites have grown over the Conichalcites which allow the bright green color to shine through. Conichalcite is not rare from Ojuela but such large, showy and esthetic specimens are rare. Excellent example of this important specie and very fine for this classic mine as well.

Andradite - Grossular series (Grandite aka Mali Garnet)
stock #15.1-040
Sadiola Mine
Kayes Region, Mali
4.3 x 4.1 x 3.8 CM (miniature)
price: $70
Late Summer 2021

A rather sharp, well-striated Garnet crystal with several edge and face modifications. The exterior is a mahogany brown but a gemmy green interior is seen in several geometric pits on the crystal where smaller Garnets were attached. This intermediate form of Garnet can be a mixture, or in this case, zoned with both species. The old name for this was Grandite and some have called these Mali Garnet. An affordable example of this interesting type of Garnet.

Orpiment and Barite
stock #8.AE-976
Elbrusskiy Arsenic Mine, Elbrus Mt
Kabardino-Balkaria, Russia
9.4 x 6.8 x 3.8 CM (cabinet)
price: $390
Late Summer 2021

Rich color and sparkling luster from red-orange Orpiment crystals that form a mound on this cabinet sized specimen. There are several white to clear Barite crystals scattered on the Orpiments adding a nice contrast. These are mostly rather small but reach up to 1 CM. With magnification the Orpiment crystals are very gemmy sharp prisms but by naked eye it is just a glittering carpet of tiny red crystals. The specimen is sawn on the bottom from when it was removed from the host rock but that is not visible. As a result it sits well for display on its own. The outer edges of the Orpiment are a yellow to orange color and several radiating fans or bursts of the crystals form the outer edges of the more red core of this piece. This find was quite important and was made in 2002, The intense color of these Orpiment was unusually vivid and it seems these are color stable as well so they are still vibrant. Not often available now, this discovery seems to have been unique in its character.

Magnesite with Uvite
stock #21.1-174
Bahia, Brazil
6 x 4.3 x 3 CM (cabinet)
price: $1200
Late Summer 2021

A killer, well crystalized Magnesite with the addition of yellow to green Uvite crystals from the now classic finds at Brumado. These are considered by most collectors to be the very best Magnesites ever found worldwide, and this is a superb example. This is a very early specimen from the first imports of the late Luis Menezes, and with a rare perfection and quality. The Magnesite is super clear, very sharp and the largest crystal is 3.4 CM. We have not seen any good or new specimens for the past few years. The arrangement of the rhombs on this specimen is especially esthetic and the Uvites are also glassy, colorful and add a nice contrast.

Smithsonite - vivid green
stock #21.1-276
Choix, Municipio de Choix
Sinaloa, Mexico
8.3 x 3.5 x 1.6 CM (cabinet)
price: $390
Late Summer 2021

A rich, wet-look green Smithsonite from the great early finds at Choix, mined by Benny Fenn Sr. This is a thin plate with minimal matrix behind a lustrous layer of Smithsonite. This is an unusually deep color for this locale (which had an amazing array of colors and hues). Comparing Smithsonite colors from around the world it is hard to find an exact match, some similarity to a few Laviron, Greece pieces and of course the Kelly Mine of New Mexico are noted but this particular hue really does not match those locales. In excellent condition, this is am older specimen and the mine is abandoned now so there may never be more like it.

Pyromorphite with Stolzite
stock #21.1-275
Broken Hill, Yancowinna County
New South Wales, Australia
5.8 x 4.3 x 3.6 CM (cabinet)
price: $425
Late Summer 2021

A rich, classic Pyromorphite specimen with several areas of orange Stolzites in tiny crystals. There are two generations of light and darker brown Pyro crystals reaching over 3 CM, all are quite glassy. As can be seen there are a number of broken crystals though several are complete. The Pyromorphites are in a jumbled mix resting on a small zone of matrix where the Stolzites are located. The Stolzite and some of the lighter Pyromorphite are fluorescent in long to mid range UV. The damage on this piece keeps it from being far more costly, but it is still an attractive Australian Pyro, the damage can be minimized by display angle. Nearly every Broken Hill piece we have handled has had at least some tip damage on close inspection, it seems they grew in small voids where extraction was difficult due to contact with the pocket walls. These crystals are all transparent to translucent with bright luster. This still looks quite nice but not for perfectionists. However with the Stolzites added this is a rare and desirable association.

Quartz with Hematite
stock #21.1-272
Lechang Mine, Lechang County, Shaoguan Prefecture
Guangdong Province, China
6.7 x 4.5 x 3.7 CM (cabinet)
price: $420
Early summer 2021

Red Quartz crystals are clustered with bladed Hematite in an esthetic presentation. This piece has 6 terminated free standing prisms, all with some orange to red color. From the display side there is no visible damage, however, on the back some damage can be seen. The Quartz has very good transparency and the terminations are clean and sharp. This find was big news in the mineral world about 15 years ago, but no new material has come out for quite a while. We have handled quite a lot of the Quartz from Lechang and it is rare to find any without considerable damage; this is much better than typical.
