Malachite replacing Azurite, Exceptional Tsumeb classic
stock #7XE-099
Tsumeb
Otavi-Bergland district, Oshikoto, Namibia
9.8 x 6.2 x 3.3 CM (cabinet)
price: $4900
Pre Holiday 2017

Incredible form, with large sharp crystals showing classic Azurite shape covered by silky Malachite. In exceptional condition, the biggest crystal in this cluster is textbook habit, doubly terminated and 6.3 CM long. A few areas of Azurite remain, with Balydonite and Olivenite present as well. Ex N.Collins and A. Edwards collections. Impressive display impact, in clean undamaged condition, this is a top quality Tsumeb piece likely from the 1920-30 vintage years.
Fluorite- Classic English, with Galena
stock #15.1-554
Weardale North Pennines
Durham, England
9.2 x 6.2 x 4.9 CM (cabinet)
price: $290
Pre Holiday 2017

Big, zoned purple Fluorites crystals with sharp edges and classic face modifications. As is typical of some english Fluorites like this there is daylight fluorescence. The outer edges of the cubes are clear while the center is a milky white to pale purple. In exceptional condition damage wise, there are a few dull Galena crystals with Goethite overgrowth that adding contrast. From an older collection, this was collected long prior to 1970. The largest cube is over 5 CM diagonal and the condition is excellent damage-wise.
Fluorite
stock #17.1-882
Xiayang, Yongchun County, Quanzhou Prefecture
Fujian, China
5.1 x 4 x 3 CM (cabinet)
price: $550
Pre Holiday 2017

An incredible example from a new find of inky blue Fluorites which has been making big mineral news. Sharp, lustrous and gem clear cluster of modified cubes that some are calling "Tanzanite color Fluorite" which is a controversial name. This also shows a pronounced color change in some lighting from deep royal purple to this rich blue that is quite unique. We have examined many of these and selected the very best in terms of color, clarity, condition and esthetics. This is far better than average, very minimal damage with contacts at outer edges and back with the main display face clean and pristine. It seems this find is fairly large but very few pieces are anything close to this quality and the prices can be very high. From Fujian Province, the earliest specimens from this find had some misleading location data. The locality we are listing has been confirmed as correct for this specimen but there may be other spots nearby as well. A choice, attractive specimen and a very good value.
Diopside with Grossular, intense green
stock #15.1-459
Orford Nickel Mine, Brompton Lake, Sherbrooke
Quebec, Canada
6 x 5.8 x 3.8 CM (cabinet)
price: $780
Pre Holiday 2017

Bright green Diopside with emerald green micro Grossular in an esthetic cluster from the famed Orford Mines. The Orford Nickle mines produced some excellent Diopside crystals but mostly grey or pale green in color. These very bright green crystals were often called "Chromian" for the color, but now are considered to be colored by Nickle instead. No matter the source these are an especially rich green and this specimen has many well formed, sharp and esthetic prisms to 1.5 CM tall. Very attractive and quite rare.
Catapleiite and Aegirine
stock #17.1-AX16-497
Mont Saint-Hilaire, Monteregie
Quebec, Canada
7.4 x 2.8 x 2.4 CM (cabinet)
price: $2400
Pre Holiday 2017

A fine sculptural cluster of big (over 2.5 CM) Catapleiite crystals in rosettes are well placed on contrasting Aegirine crystals. Mont St Hillaire Catapleiites are considered the best ever found, although the Lovozero find was also world class, these had a sharp glasslike form unequaled. This is one of the most desirable St Hillaire species, and this is a far above average quality specimen. Well composed with several rosettes, all well formed and lustrous. A modern classic, these are very hard to get in this larger size and sharp quality. These are now almost never available like this.
Vesuvianite- single Crystal
stock #17.1-AX-840
Jeffrey Mine, Asbestos
Quebec, Canada
3.2 x 1.1 x 1.0 CM (miniature)
price: $890
Pre Holiday 2017

The Vesuvianites that came out of the Jeffrey Mine are the most colorful and desirable in the world. This crystal has a two tone green color, gem clear areas and a sharp, perfect termination. Close examination shows what may be parallel growth or complex twinning. Overall a fine condition, undamaged prism with excellent color and bright luster. Found in 2002. Relatively affordable for this level of quality. Since the mine closed, these are fast becoming rare and very expensive when available.
Topaz on Amazonite single crystal
stock #17.1-534
Hohenstein Massif, Omaruru District
Erongo Region, Namibia
6.8 x 6 x 4.8 CM (cabinet)
price: $525
Pre Holiday 2017

A big, blocky Microcline (Amazonite) crystal with several faces sprinkled with clear Topaz Crystals. A fine Erongo specimen that comes from the hard labors of the small miners on Hohenstien. The Topaz are up to 8MM in sizesharp, gemmy and most are colorless. The back of the specimen is contacted but the front and sides are in excellent undamaged condition and displays well. The green color of the Amazonite is not very often seen from this area, it makes a fine setting for the clusters of Topaz.
Vanadinite- Intense red, modern classic locale
stock #17.1-746
Pure Potential/ N. Geronimo Mine, Silver dist., Trigo Mts, La Paz County
Arizona, United States
7.1 x 4,9 x 3.2 CM (cabinet)
price: $420
Pre Holiday 2017

The Pure Potential (or North Geronimo) mine has become famed for outstanding Vanadinites, some of the best ever found in the Americas. Top pieces have an intense red color that is distinctive. This piece has that color and crystal sizes are above average for the hexagonal non hoppered type. Well isolated on a contrasting dark matrix the specimen has fine luster and flash. Several of the Vanadinites have some Calcite prisms sprinkled on them best seen with magnification. Nearly perfect only one small zone has some micro damage, the rest of the hundreds of sharp crystals are impressively perfect. The mine closed back to the late 1800s but in the past few decades has been worked for specimens with occasional finds of fine pieces like this. A USA classic and a pretty specimen from anyplace.
