A stunning specimen of this classic Tsumeb calcite style, with forest-green dutftite included inside the calcite crystals but only along certain axes, creating an amazing visual effect! This is one of the better examples of this material for its size, and comes from the noted collection of Colorado dealer and collector Mitch Gunnell. 10 x 7 x 6 cm
A shocking calcite specimen where the crystals are so heavily included by hematite that they look almost like a different species entirely. High lustre and pristine condition make this a unique and unusually fine specimen, especially as calcites of this size and condition are even more uncommon from Tsumeb than from other localities. It was purchased from Charlie Key in 2000. 14 x 10 x 4 cm This Photo was Mindat.org Photo of the Day - 24th Apr 2006
An unusual specimen showcasing stark color contrast between oriented duftite dusting and the snow-white rhombohedra of calcite that has an extra-high lead content, a varietal unique to Tsumeb. 10 x 8 x 5 cm
A very showy specimen featuring an unusually well-preserved large rhombohedral crystal perched on contrasting matrix (duftite-coated dolomite). Complete save for some contact on the back, this is as fine a Tsumeb calcite for the size and crystal form as you could ask for. 9.5 x 6 x 6 cm
A really unusual and interesting calcite specimen featuring the classic sharp rhombohedra that Tsumeb is most famous for, but in a context that shows a lot of character. The open vug is chock-full of sparkling, gemmy rhombs, and the contrast with the bright grassy-green duftite makes the piece colorful as well as sculptural. 10 x 6 x 4 cm
This is a most unusual specimen, which I call "fire and grass", that they purchased in Namibia in 1987. the leftmost third of the specimen is included by bright green duftite and the rightmost 2/3 by ruddy red-orange hematite, with very little admixture in-between. I have never seen another piece like this from Tsumeb, with such a mix. The lustre, as you can tell, is phenomenal and the piece is near pristine. One of my personal calcite favorites! 12 x 11 x 7 cm
This unusual specimen is visually impressive in person, and consists of scallop-shaped yellow calcite crystals enveloping and topping a double-stalactite of dolomite. 10 x 8 x 7 cm
WOW! Talk about "fine," this twin of Chinese quality is pound for pound the finest Tsumeb calcite I have ever seen. Small, yes, but just incredible quality. This pristine , matrix specimen was purchased directly from the Zweibels in 1992 and has been since then the finest miniature calcite (or large thumbnail) known to me from Tsumeb (by way of qualifying that statement, which I do believe, I should add..."for my tastes"). 3 x 3 x 2 cm
A unique specimen, so richly included with dendritic mottramite that there might even be more mottramite than calcite inside of it! I think the pics pretty much show how interesting, colorful, and dramatic it is...both sides are pristine, and shown in the images. Moreover, it is a floater. 5 x 4.5 x 3 cm
This dramatic piece features sparkling, lustrous, pristine yellow calcites perched on a carpet of sparkling, chatoyant malachite. Prosper Williams sold it in 1976 to the Los Angeles County Museum, from whence it was traded to the Marion Stuart Collection in a rare deaccession in 1977. It was the Sussman's first choice specimen when the Stuart collection was broken up at Tucson in 2000, and they waited in line to be the very first people into Dave Bunk's booth at the opening of the show. I know this because myself, Steve Neely, Steve Smale, and a number of others also really wanted this specimen at the time and we were all waiting in line BEHIND Marshall's bald head to get it on the offchance he did not (grumble...). 16 x 7.5 x 8 cm This Photo was Mindat.org Photo of the Day - 1st Sep 2006
A VERY choice specimen from this one famous pocket of calcite with included copper, that gives it a wonderful pastel green hue unique to my knowledge. The rough surface looks like sugar, brilliant and sparkly ! This is not a true species per se, but rather a varietal of calcite. Nevertheless, it is unusual stuff from a one-time find and the Sussmans seem to own two of what are regarded as the best small cab and cabinet specimens from the find. 6 x 5x 4 cm
A VERY choice specimen from this one famous pocket of calcite with included copper, that gives it a wonderful pastel green hue unique to my knowledge. The rough surface looks like sugar, brilliant and sparkly ! THIS SPECIMEN IS COMPLETE ALL AROUND, PRISTINE, and regarded as the finest large specimen from the pocket according to many people I have talked to. This is not a true species per se, but rather a varietal of calcite. Nevertheless, it is unusual stuff from a one-time find and the Sussmans seem to own two of what are regarded as the best small cab and cabinet specimens from the find. 17 x 9 x 9 cm
7.3 x 5.0 x 3.1 cm. A fine specimen of a rich cluster of lustrous, jet-black babingtonite crystals aesthetically perched atop lustrous, gray calcite rhombs and nicely accented with pastel-green prehnites from the famous Lane Traprock Quarry in Westfield, Massachusetts. Ex. Robert Lavinsky and Evan Jones Collections.
7.0 x 6.4 x 4.5 cm. A superb specimen of a 3.5 cm wide, gorgeous, glassy, V-twinned, butterfly calcite very aesthetically perched on a very well prepared, sawed matrix and very nicely complimented by smaller calcites from the famous 884 Mine of Hunan Province, China.
8.3 x 6.5 x 6.2 cm. A superb, old-time cluster of translucent, lustrous, pastel-pink, modified rhombohedral manganoan calcite crystals with unusual cobblestone-like stepped terminations, and from the famous Samson Mine at St. Andreasberg, Germany. This has an excellent orange fluorescence which, like the color, is rare in calcite from this region. Ex. Miller Calcite Collection.
