Barite with Malachite inclusions
Likasi, Katanga Copper Crescent
Democratic Republic of Congo (Zaire)
5.9 x 3.2 x 4 CM (cabinet)
pre Tucson 2015 update
Esthetic, sharp green and glassy Barites are perched on a matrix along with some small zones of Malachite in an attractive specimen. From the famous finds of the 1980-90's this is a very colorful Barite with several nice angles for display. In very good condition, there is a little minor chipping mostly on the backside and not noticable without magnification. A good value, these have become quite expensive and few are this attractive.
Topaz with, Elbaite, etc.
Murzinka Mine,Sarapulka Dist., Sverdlovskaya Oblast, Middle Urals
3.6 x 2.6 x2.4 (small miniature)
A small but very esthetic version of classic light blue topaz from the Urals. A gem clear crystal with pale blue color at 1.9 CM in size is neatly perched on contrasting matrix. Small additional crystals of Tourmaline are on the matrix adding interest. Very good condition damage wise this presents nicely.
An older, well formed amber colored Barite from the Sulcis area of Caligari in Sardinia. Ex. Mineral Gallery (K. Ward) This shows several good phantoms with backlighting, and has a second generation overgrowth in some areas. Over all in fairly good condition there is contacting on one side and at the rear, small edge chipping is present but not easily seen from the logical display angle. A nice, good color piece from a classic local with the main crystal reaching 4.8 CM.
Mt. Xuebaoding, Pingwu Co., Mianyang Pref.
8 x 7.4 x 5.9 CM (cabinet)
A well placed cluster of lustrous Cassiterite perched on the classic Muscovite matrix of Mt. Xuebaoding. Very nice presentation and contrast, the Cassiterite is just over 4 CM across and in very good condition. By naked eye there is no damage but good magnification shows slight edge chips that are not at all distracting on display.
An early piece of well formed multi-color tourmaline from the now famous deposits at Luc Yen, Vietnam. Very sharp and with glassy luster, this is in superb condition with no visible damage to the crystal. Better in person and a little more gemmy than the photos show. This is quite likely a mix of Elbaite and Liddicoatite but has not been analyzed to determine this. Ex John Marshall collection, this is well above the quality of the vast majority of these Tourmalines, and a nice addition to any suite.
Flux Mine, Patagonia
3.6 x 3.1 x 2.4 CM (small miniature/ large thumbnail (toenail))
A very esthetic, 3 dimensional specimen with well formed delicate crystals from the great finds of the 1980's at the Flux Mine. These are all quite delicate and usually show considerable damage, but this is an unusually pristine example. The sprays of Cerussite contrast with the black matrix very well. This can be packed and shipped but we recommend insurance since it is so delicate. Now an American classic this is a far above average toenail specimen.
Bright, lustrous, gemmy lemon yellow Chabazite crystals are scattered in an open vug segment. Very unusual color and clarity, this specimen was collected sometime before 1940. The typical color for Chabazite from Nova Scotia is salmon to orange red and is opaque to slightly translucent. These are glass clear, gemmy and up to .8 cm. Esthetic and an important Canadian specimen.
Fluorite on Quartz
11.4 x 10 cm (cabinet)
Two deep purple cubo-octahedrons etched from the quartz matrix are well placed and displayed with great form and contrast. In fine condition with no damage, however the fluorites do show some stress cracks as do almost all of these. Some color changes can be noted in this fluorite in different light sources.
