A complex and unusual Tsumeb specimen from the important collection of Cors De Bruin who was employed at Tsumeb starting in 1947. His label gives us the rare detail of locality (30 Level) and has his observation "real mixed-up thing!". The matrix is a heavy mass of Copper/Cuprite that is host to several vugs and zones packed with small crystals and botryoidal masses. The Wulfenites here are mostly the bipyramidal habit. This small specimen is loaded with Copper, Zinc and Lead minerals, the kind of mixing that really only is seen at Tsumeb and one of the reasons it is so revered by collectors.
Heliodor - classic form gem Beryl crystal
stock #16.1-519
Padre Paraiso, Jequitinhonha Valley
Minas Gerais,
Brazil
3.2 x 1 x .9 CM (thumbnail)
price: $900
Pre Tucson
A very fine gem crystal thumbnail. This is a small version of the famed etched Beryls from the golden years of Brazilian pegmatite discoveries. In excellent condition, this has the typical flat termination and all faces have various sorts of geometric etching. The luster ranges from a matte satin to bright glassy in some areas. Nearly 100 percent of the crystal is gem transparent though there are inclusions to note. Ex Les Hitchings collection this was obtained in 1979 on his trip to Brazil. It is not common to find thumbnail sized crystals of this quality.
Pyromorphite
stock #8.AE-888
Daoping Mine, Gongcheng County, Guilin Prefecture
Guangxi Province,
Chile
4.8 x 4 x 3.1 CM (miniature)
price: $330
Pre Tucson
Apple-green Pyromorphite in fine condition from the classic Daoping mine finds of the early 2000 era. This specimen has 4 different habits of unusual crystallization form present and almost none of the common styles. An excellent specimen for a serious suite of Pyromorphites or for odd habits and rare forms. Elongated spindles, stretched wave forms and others are present. In fine condition, this is nicely attractive on a shelf but amazing and complex when examined closely or with magnification.
Wulfenite with Mimetite
stock #AX-21-044
Rowley Mine, (Reliance Mine), Theba, Painted Rock District
Arizona,
United States
2.8 x 1.8 x 1.7 CM (thumbnail)
price: $700
Pre Tucson
Wulfenite from the Rowley mine is instantly recognizable, very desirable and regarded as some of the most elegant in the world. This is a choice thumbnail with fine color, form and visual impact. From some angles the form looks like a butterfly with two main crystal wings on matrix. Some small bits of Mimetite contrast as well on the matrix. In exceptional condition, the crystals are the windowpane type and are impressive from all angles.
Adamite (Cuprian)
stock #23.1-644
Mina Ojuela, Mapimi
Durango,
Mexico
4.9 x 3.4 x 2.9 CM (miniature)
price: $120
Pre Tucson
Classic Adamite crystals from Mina Ojuela but with the more rare color. Well-defined mint green crystals on contrasting gossan matrix in good condition as seen. The crystals have glassy faces and translucent milky interiors. A nice affordable and attractive Adamite from this most incredibale locality. This can be trimmed to a pair of thumbnails but we like it as is.
Fluorite
stock #16.1-737
Aouli. Midelt, Khenifra Province
Meknes-Tafilalet Region,
Morocco
5.3 x 3.2 x 2.8 CM (cabinet)
price: $390
Pre Tucson
An above average bright yellow Fluorite from Aouli (Morocco). The matrix between the yellow cubes is also Fluorite but a red-orange color and not well crystalized. The matrix gives a very nice color contrast to the main crystals. In very good condition, the corners and edges of the Fluorites are sharp and well-defined. A crack is noted on the largest crystal, it is not repaired and is all natural with no sign of damage. Found about 5 years ago, this has a different look from more recent finds.
Grossular with Heazlewoodite, Clinoclore and Gold!
stock #AX-16-431
Jeffrey Mine, Asbestos (now Val-des-Sources, Estrie,
Quebec,
Canada
5.3 x 3 x 3 CM (small cabinet/ large miniature)
price: $1500
Pre Tucson
An important and exotic piece from Jeffrey Mine, this has the deep green gemmy Grossular (so called Chrome Grossular) scattered on a matrix of Clinochlore etc. This alone is not so exotic or important, but both Heazlewoodite and native Gold are. While this is an attractive specimen of brilliant Garnets, the main interest (for some) is several very well-formed, sharp tiny crystals and clusters of Heazelwoodite. Seen with magnification these are textbook sharp, of course this is a rare mineral worldwide and very rare at Jeffrey. But what makes this even more important is only seen starting at 40 X magnification and best revealed at 80-100x. There are several tiny but distinct crystals of Gold some of which are elongated. Of course this is all micro sized but super-rare and impossible to find material from this world-class locality. Aside from the exciting micros, the overall esthetics of the bright green Grossular is attractive in its own right. Unfortunately our photographs at very low magnifications can not show the micros properly, but they may be rephotographed later on with specialized gear.
Wurtzite, Bismuthinite and Quartz etc.
stock #6.2-842
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province,
China
5.2 x 4.3 x 3.2 CM (small cabinet/ large miniature)
price: $750
Pre Tucson
A well-formed Wurtzite crystal cluster on a complex multi-specie specimen from the amazing Yaogangxian Mine. The specimen has several Quartz crystals that are partly coated with Muscovite and sprinkled with metallic hairlike crystals of Bismuthinite. The Wurtzite is mostly seen in a 2.2 CM diameter cluster of stacked brown-red crystals that have a bright luster. In some photos these look silvery metallic due to the reflections on the surface but in hand the color is typical dark brown to almost black. Wurtzite from Yaoganxian is a very rare specie, this is the largest and best we have seen and is exceptional for the locality.
