Brochantite (exceptional acicular crystals)
stock #10.1-260
Milpillas Mine, Cuitaca, Municipio de Santa Cruz
Sonora, Mexico
6.6 x 4.6 x3.3 CM (cabinet)
price: $1400


An extraordinary, delicate, electric green Brochantite from what may be the best discovery ever of the species. In person the color is an intense emerald green deeper than can be rendered on most computer monitors. Perfect condition, strong esthetics and intense color make this piece stand out in any display. There have been only a few small pockets of Brochantite over the past few years at Milpillas which is far better known for incredible Azurites. There have been very few fine specimens in these finds, and none recently. Without a doubt these will be regarded as some of the best of the specie ever seen, and are a fine affordable investment. This specimen can be shipped with special arrangements but it is far safer to deliver in person at a major show or by other arrangement.

Sphalerite (ruby-jack and black jack)
stock #0018-JM-1303
Pitcher, Ottawa County
Oklahoma, United States
8x 5.4 CM (cabinet)
price: $150


A much better than average tri-state classic, ex John Marshall collection. Crystals to 3.6 CM on a thin matrix plate range in color from translucent ruby-red to black. Pitcher Field produced huge numbers of Sphalerites 40+ years ago, it is now rare to see good ones. In fine condition, well-composed and far more attractive than is typical.

Azurite with minor malachite
stock #7-MOR-209
Touissit, Touissit-Bou Beker Dist., Jerada Province
Oujada-Angad Province, Oriental Region, Morocco
7 x 4.3 CM (cabinet)
price: $750


A cluster of highly lustrous sharp Azurites to 3.4 CM in size with scattered accents of green Malachite. From the 1980 vintage finds at Touissit, this is a very eye-catching and attractive example. The largest crystals are in excellent condition chipping and contacts do exist however that can not be seen from the main display angle. The luster is glass-like, far better than most Touissit pieces.

Skutterudite (large crystals on matrix)
stock #11.1-W60
Bouismas Mine, Bou Azzer District, Tazenakht
Ouarzazate Province, Morocco
6.8 x 5.4 CM (cabinet)
price: $380


Big (up to 4.2 cm), sharp shining metallic silver crystals clustered on matrix. Esthetic with better than average presentation, this is excellent specimen of this cobalt arsenide. Without doubt the Bou Azzer area produced the very best of the specie, prior to these the best were German, rare, expensive and far less pretty. The display side of this is in excellent condition. It is contacted on the right side and has damage at the rear where it was removed, not seen in normal display. This locality still produces a few good pieces every few years but it will not last forever. These are future classics especially when they are this good.

HOLD Malachite (fibrous primary crystals)
stock #HOLD 8.1-188
Katanga, Central Area, Katanga Copper zone
Shaba, Democratic Republic of Congo (Zaire)
8.5 x 5.6 CM (cabinet)
price: $95


A fine, fibrous crystallized primary malachite from the prolific mines of Katanga. Excellent color, satin sheen and luster, no damage. Malachite crystals over 3 CM abound. The recent finds of this material have been well appreciated, affordable and very attractive. Not all fine minerals are expensive!

Rose Quartz (very large crystals)
stock #AC-361
Alto da Pitorra, Laranjeiras, Galleia, Doce Valley
Minas Gerais, Brazil
9.1 x 8 cm (cabinet)
price: $750


A big, very showy old time rose quartz with rare large well formed crystals. For some reason rose quartz prisms are nearly always little more than druse sized, a centemeter is sizable for the specie. On this specimen several crystals reach over 2 cm, most are quite gemmy and have attractive color. To add to the eye appeal, there are some crystals that have an orangeish hue, this seems to be cased by the color of parts of the matrix coming through the gem clear prisms. There is chipping damage to crystals at the outer perifery and some other chipping can be seen with magnification, but none of this is at all distracting. The condition is fine especially for such a large specimen. There is a small sawn area on the back that could be used as a base if desired, it is not at all visible from display angles. Vintage early 60's I have not seen anything quite this fine for sale in a very long time. Far better in person!

Fluorite (color-change complex)
stock #5.1-105
Shangbao Pyrite Mine, Leiyang
Hunan Province, China
7.6 x 5.8 CM (cabinet)
price: $430


The sort of fine Fluorite that the Shangbao Mine has become world famous for. From finds in 2006, this habit has been found occasionally since and several large examples are known (and have sold for very high sums). This is simply a very esthetic smaller fluorite (3.3 CM) perched on crystallized dolomite with a few quartz crystals. Excellent condition, the fluorite also has a color change in different lighting from purple to blue. A very desirable and unique habit, in a relatively affordable specimen.

Fluorite (modified octahedral) on Muscovite
stock #10.1-317
Mt. Xuebaoding, Pingwu Co., Mianyang Pref.
Sichuan Province, China
6 x 4.2 CM (cabinet)
price: $200


From the high elevations of Mt Xuebaoding (better known for Scheelites and Cassiterites), this ice-like fluorite shows the rare habit of octahedron with a cube face on the tip of each corner. The surface has the "melted" look the re-crystallization makes and has a pleasing esthetic. Ex Bert Ottens and Marty Zinn Collections, this type of Fluorite is no longer being found and is a great addition to any serious Fluorite suite.
