Arsenopyrite (twin) on Muscovite and Quartz
stock #6.2-895
Yaogangxian Mine, Yizhang County
Hunan Province, China
4 x 3 x 2.7 CM (miniature)
price: $330
Dec 2018

A perfect main Arsenopyrite crystal with textbook form well perched above the matrix of Muscovite and Quartz crystals. Brilliant metallic luster, no damage and great esthetics, a very choice miniature for the specie. The main Arsenopyrite is just over 2 CM and has a penetrating crystal (twin) that is in a X form, but is not very evident from the logical display angles. From finds almost 10 years ago at Yaoganxian. Hard to photograph the brilliant luster, this is great in person.
Apophyllite
stock #18-AX-24-493
Jeffrey Mine, Asbestos
Quebec, Canada
2.9 x 2.4 x 1.6 CM (thumbnail)
price: $250
Dec 2018

An excellent thumbnail of quite fine Apophyllite from the legendary Jeffrey Mine. World famed for the Garnet and Vesuvianites, Apophyllite is much more rare and almost never available. The crystal here is lustrous and has distinctive well formed striations and stands apart from the matrix well. An worthy addition for a Jeffrey mine suite.
SOLD Quartz Var. Amethyst
stock #SOLD 18.1-568
Piedras Parado, Las Vigas
Veracruz, Mexico
3 x 1.9 x 1.8 CM (small miniature/ large thumbnail (toenail))
price: $0
Dec 2018

Undamaged, attractive well crystallized mineral specimens are usually quite expensive, but there are a few exceptions. This find of Amethyst is one of them. Choice small Veracruz Amethyst cluster with fine color, clarity and form. One of the last great bargains in the mineral world.
Torbernite - Exeptional modern classic
stock #18.1-530
Margabal Mine, Entraygues-sur-Truyere, Averyron
Occitanie, France
6.1 x 4.7 x 3.2 CM (cabinet)
price: $3200
Dec 2018

Outstanding cabinet sized Torbernite with rich green color and incredible crystal form. From the last great finds at Margabal, this is a superb piece in impeccable condition. There are two habits of Torbernite showing two generations on this piece, the largest being the fans of splayed plates. This size and quality is top percentile and the deep forrest green is impressive, but far better in person.
Calcite balls with Quartz and Actinolite
stock #16.1-177
Huanggang Mine, Chifeng Prefecture, Hexigten Banner, Ulanhead League
Inner Mongolia Region, China
7.2 x 5.5 x 3 CM (cabinet)
price: $190
Dec 2018

A remarkable and strange Calcite formed of spherical clusters of flat crystals. The balls are connected in a chain and these are covered with bright sparkling Quartz in tiny doubly terminated clear crystals much like Herkimer Diamonds. A scattering of Hairlike Actinolite crystals are seen with magnification impaling both the Quartz and Calcite. Choice and in excellent condition, the esthetics are impressive. Another of the mineral wonders from the incredible deposits at Huangang.
Cerussite on Azurite
stock #18-AX-27-086
Poteryaevskoe Mine, Rubtsovskoe Cu-Zn-Pb deposit, Rudnyl Altai
Altaiskii Krai, Russia
5.2 x 3.3 x 2.5 CM (cabinet)
price: $725
Dec 2018

The fantastic finds of Cuprites at Rubtsovskoe was huge news a few years ago, and made the region famous. Recently some very attractive Azurites have turned up but only a few associated with Cerussite. This example has a reticulated cluster well placed on contrasting crystallized Azurite. Excellent color and form, a fine addition to any copper suite and will fit well with the Cuprites and coppers that are so well known from here.
SOLD Red Beryl (Twinned?)
stock #SOLD 13.1-333
Thomas Mountains
Utah, United States
.9 x .8 x .7 CM (thumbnail)
price: $0
Dec 2018

A doubly terminated red Beryl (Bixbite) from the Thomas Range that looks like a true penetration twin. Twinning in Beryl is very rare, some writers say it never occurs, most often twins are actually joined parallel growths . This specimen certainly looks like an actual twin, the structure is correct and the original collector who had this specimen had exhibited it widely in his displays of twin types. We have not had an xray study done but are passing this on with a question mark on the twinning question. For the right collector this can be a fun bit of research and is a nice Beryl no matter what the form is. The crystal is complete and has no damage but a few micro contacts and natural pitting on edges. Red Beryl is of course rare itself and a twinned specimen (if so) is quite special.
Cobaltoan Calcite and Malachite
stock #18-AX-12-019
Mashamba West Mine, Kolwezi, Katanga Copper Crescent
Katanga (Shaba), Democratic Republic of Congo (Zaire)
6 x 4.4 x 4.2 CM (cabinet)
price: $640
Dec 2018

The Cobaltoan Calcites of Mashamba have been gone for more than a decade now, but they are still considered to be some of the best and most intensely colored ever found. This specimen has the most desirable contrast with a small matrix of green Malachite and has several generations of pink to clear Calcite displayed. Sadly there are some edge cleaves or contacts but the overall specimen condition is very good and still displays well. The best Scalenohedral crystals are remarkably clean and free of chipping. There are several possible display angles. Now very hard to get in the mineral market these are unique and quite sought after.
