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
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.
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
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.
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.
HOLD Copper and Mimetite etc
stock #HOLD 16.1-664
Tsumeb
Otjikoto Region,
Namibia
4.1 x 3.2 x 2.3 CM (miniature)
price: $125
An unusual multi-specie piece from the incredible Tsumeb Mine. Native copper in branching fingers and thin wires are protruding from a complex matrix with a few yellow Mimetites crystals among other species. Tsumeb is famed for its odd mixtures of species, forms and chemical elements. A cute miniature that has the uncommon combination of Copper and Lead elements.
Quartz - with inclusions of red Hematite
stock #AX-11-095
Orange River, Namakwa
Northern Cape Province,
South Africa
5.5 x 1.7 x 1.5 CM (small cabinet/ large miniature)
price: $280
The occasional finds of red Quartz from the Orange River area of South Africa are well-known in the mineral world. This is a choice example with better than usual color intensity and nice form. Conjoined crystals of Quartz with transparent tops and opaque lower sections that contrast with the bright terminations. In great condition aside from a tiny tip contact that is hard to see with naked eye. This piece is from the last good find that was more than 5 years ago. An excellent value for quality / esthetics to price.
Although Siderite is a common mineral, it is quite rare from Tsumeb and gemmy crystals are very rare. This specimen is not very showy by naked eye but the massive Germanite ore hosts a vug with lustrous honey-yellow to orange color Siderite crystals. These are best viewed with magnification as the vug is just 1.3 CM across. A very nice addition to a comprehensive Tsumeb suite, I am told this was a limited find very deep in the mine near the end of production.
SOLD Malachite on Quartz with Geothite
stock #SOLD TMP-5582B
Mindingi Mine, Kambove District
Katanga (Shaba),
Democratic Republic of Congo (Zaire)
8.3 x 5.5 x 3.6 CM (cabinet)
price: $0
A fine and pretty piece from a new find of botryoidal Malachite on contrasting orange-red Quartz. The Malachite balls are very well-defined and have good separation. In excellent condition, the only chipping is the outer edge where this was removed. The center of the specimen is very eye-catching hosting velvety luster green balls on bright sparkling red Quartz. It is a surprise to learn that the color of the Quartz is not due to Hematite as is normal but a much less common effect of Goethite inclusions. As far as I know this is the only example of Goethite coloring red Quartz. No matter the reason the overall effect is striking and especially nice in person.
SOLD Fluorite - USA classic
stock #SOLD 23.1-645
Stoneco Auglaize Quarry, Junction, Paulding County
Ohio,
United States
2 x 1.7 x .9 CM (thumbnail)
price: $0
A small but choice thumbnail of zoned Fluorite from a find at the Auglaze Quarry of Junction, Ohio more than 35 years ago. Ex collection of Larry White, this has excellent form, condition and very nice zoning. It can be oriented in several ways, there is no damage. A contact with a little matrix on the backside is noted but not seen on display. This is a good example from this important Fluorite locality in the Findley Arch Geologic zone.
