4.9 x 3.1 x 2.6 cm. A very rich and exceptional specimen of bright canary-yellow, botryoidal kleinite on starkly contrasting, snow-white calcite matrix from the McDermitt Mine of Nevada. Kleinite is a very rare mercury halide, known from only 3 localities worldwide.
3.0 x 2.0 x 2.0 cm. An exquisite, 2.0 cm, gemmy, butterfly-twin calcite crystal from the small, one-time find in the early 2000s from Rio Grande do Sul, Brazil. The water-clear calcite crystal is beautifully perched atop matrix of smaller calcite crystals. Calcites from this find are very rarely available now.
3.9 x 3.4 x 3.3 cm. A classic and beautiful, sharply color-zoned, purple fluorite cube aesthetically accented with a lustrous, colorless calcite scalenohedron from the Minerva #1 Mine of South Illinois. The interesting, lustrous, stepped-growth faces are entrancing. Complete-all-around, the edges are pristine. The crystal has striking, two-toned, white and purple fluorescence.
18.4 x 12.9 x 9.4 cm. A fine, large cabinet, translucent and colorless, dogtooth calcite crystal is included with hematite and is richly sprinkled with brassy, globular chalcopyrite clusters on this specimen from recent Chinese finds. This complete-all-around piece is very nearly pristine.
13.9 x 12.4 x 5.4 cm. Sharp, translucent and lustrous, light brown calcite scalenohedrons to 11.8 cm are pleasingly clustered on a thin crust of contrasting matrix on this excellent cabinet specimen from recent finds at Jalgaon.
10.4 x 6.4 x 5.4 cm. An excellent cabinet cluster of lustrous, translucent, amber calcite rhombs with the rare, nearly cubic (pseudocubic, to be more precise) crystal habit from the famous quarries at Clay Center, Ohio. The large, central crystal is 1.7 cm on edge. Superb and rare, old-time material for the locale. An accompanying Albanese label dates from 1953-1968. Ex. George Feist Collection # 2472.
These moderately gemmy crystals are quite good for the locality, and the cluster of two of them measures 2 cm across. Perched nicely against contrasting matrix of massive calcite, this would be one of the better such specimens to have come out! Most are broken and jumbly...truly, this was the pick of the lot. The stone below is , for what it is, equally impressive! 5 x 4.1 x 2.5 cm
Well-crystallized Himalaya calcite is rare! 2.5 x 2.4 x 2.2 cm
Rare and extremely aesthetic combination! 2.3 x 2.2 x 2.1 cm
A gorgeous, complete-all-around cluster of calcite upon a stalactitic earlier generation of calcite. New find from China! 7.1 x 3.5 x 2.1 cm
A gorgeous, complete-all-around cluster of calcite upon a stalactitic earlier generation of calcite. New find from China! 8.6 x 3.2 x 2.4 cm
Really good, unusually sharp, translucent crystals of classic Franklin rhodonite, embedded in contrasting matrix. This is a great thumbnail example - most specimens are big and clunky in comparison and good thumbs are especially hard to obtain. Beyond that, though, these crystals are very fine. 2.5 x 2 x 1.3 cm
A VERY rich and colorful specimen of green fluorite completely covering a knoll of matrix! On top of it are perched elongated crystals of calcite. This is a huge and showy locality specimen, and is the best I have seen for sale from the locality! BETTER IN PERSON! 10.4 x 6.4 x 3.5 cm
I have never seen another calcite quite like this from the location - while the curvaceous form is not unusual, the sparkling coating of secondary calcite IS most unusual, and gives the piece a unique appearance. It is a truly elegant, colorful specimen that is better in person. 11.2 x 5.6 x 3.5 cm
An unusually prettyTsumeb mottramite specimen, in that the light moss-colored mottramite is intergrown with small, gemmy rhombs of calcite, so that the whole specimen sparkles (where mottramite is generally opaque and rather dull). A really unusual and pretty Tsumeb piece! 10.8 x 5.2 x 4.3 cm
