8 x 6.1 x 5.5 cm. A fine cluster of sharp, gemmy Calcite crystals from the Wessels Mine. The lustre is excellent, too. All the crystals have complex faces, and some even have beveled edges. The largest crystal, itself twinned, is gemmy and a full 3 cm along one dimension. The crystals have the classic deep-orange fluorescence exhibited by Wessels Calcites. Ex. Charlie Key stock.
6.5 x 4.5 x 4 cm. A fine specimen of bubblegum-pink Manganoan Calcite attractively grown as a botryoidal crust on matrix. The uniform growth and very rich color make this a particularly beautiful specimen. Ex. Charlie Key stock.
7.5 x 6.7 x 4.6 cm. The Nikolaevskiy Mine in Dal’negorsk is world-famous for its water clear Fluorites, which are usually in cubes. These, however, are dodecahedrons modified by both the cube (square faces) and the octahedron (triangular faces). An unusual and rather amazing habit, especially for the locality. The largest crystal is about 2.5 cm across, and of course they are water-clear and lustrous. Combined with Quartz needles and bladed Calcites. Ex. Charlie Key stock.
5.9 x 5.1 x 3.4 cm. A fine and uncommon combination specimen from the historic mines at Trepca, Kosovo and the Jaime Bird Collection. A pretty and well-placed cluster of translucent, lustrous, fat, tabular calcite rhombs is perched atop a matrix of smaller calcites, which are richly and aesthetically sprinkled with golden chalcopyrite microcrystals and radial sprays of quartz needles. All of the calcite crystals are tinted gray by inclusions of boulangerite, which is very uncommon from Trepca. Outstanding and classic combination material from this classic locale. Essentially pristine.
7.0 x 5.8 x 4.5 cm. A classic wulfenite specimen from the Erupcion Mine and the Don Boydston Collection. Don was a prominent LA area collector in the 1960s-1970s. His "lost" collection surfaced around 2001. Highly lustrous, blocky, "sandwich style" wulfenite crystals to 1.2 cm are aesthetically and richly scattered on both side of the knob of banded, white calcite. This is a highly representative specimen of this classic style from the 1960s.
10.5 x 8.4 x 6.3 cm. A fine cabinet Elmwood calcite specimen dominated by a striking, 11.0 cm, doubly terminated crystal. This lustrous crystal has gemmy, amber tips and a colorless, central body. The smaller scalenohedron with an interesting, stepped-growth face is a very nice accent on the silicified limestone matrix.
2.3 x 1.6 x 1.2 cm. From what has to be amongst the most famous single calcite finds of the modern era in China, these sharp crystals came out around 2000. A fine thumbnail specimen of a 2.3 cm wide, beautiful, glassy, V-twinned, butterfly calcite crystal mounted on a shard of matrix. Classic and textbook calcite twinning.
5.5 x 5.4 x 4.7 cm. A fine calcite specimen from the Stoneco Auglaize Quarry of Ohio and the George Feist Collection #2741. A glassy and lustrous, 5.6 cm, doubly terminated calcite crystal dominates this fine piece. The sharp, light amber termination is particularly gemmy above the colorless, central body of the crystal. This large, upright crystal is beautifully set in a bed of smaller crystals and is complete all-around. Ex. George Feist Collection.
3.3 x 2.8 x 2.3 cm. Featuring a central 2 cm crystal, doubly-terminated and wine-red, this is a very aesthetic and attractive miniature from this find. These started trickling out 2 years ago at Munich, and the flow has been pretty thin since. This piece is comparable to the classic Italian pieces.
15.4 x 11.4 x 4.8 cm. A remarkable and rare large cabinet combination specimen from the Copper Queen Mine at Bisbee. Both sides of the matrix are covered with powder-blue to pastel-green aurichalcite. The front is richly sprinkled with clusters of glassy, colorless calcite rhombs, some of which are included with aurichalcite. This is a very uncommon association specimen from this classic locale and is almost certainly old-time material, dating to prior to World War I. Ex. Mike Cunningham and Dennis Mullane Collections.
8.0 x 4.2 x 3.3 cm. An interesting and aesthetic cluster of lightly frosted, green, chlorite-included calcite scalenohedrons from Irai, Brazil. The large crystal is doubly terminated. Ex. Jaime Bird Collection.
7.8 x 7.8 x 5.5 cm. A 1.0 cm, sharp, gemmy and lustrous, wine-red cuprite crystal is nicely set in the corner of a very sculptural vug lined with glassy, white, calcite rhombs from the Tsumeb Mine. A fine combination specimen from the Rob Smith Collection.
4.4 x 4.0 x 3.7 cm. An interesting and showy Tsumeb miniature of a 2.0 cm, puffball of lustrous primary malachite microcrystals nicely set on matrix covered with very glassy, colorless, flattened calcite rhombs. Ex. Rob Smith Collection, a noted Tsumeb collector.
21.4 x 19.0 x 9.1 cm. At 6.4 pounds, this would be a large and surprisingly pristine Tsumeb calcite even if it were just plain old typical white rhombs. But it is more interesting because of the very unusual oriented inclusions of hematite granules embedded within certain edges and edge corners. We call this a preferential coating or preferential deposition effect. In person it is very striking for the incredible geometry it creates, and the thin brown-red lines create a sharp boundary between the calcite rhombohedra which makes the whole piece more dramatic. Ex. Willy Israel Tsumeb Collection, purchased from Clive Queit in October of 1978.
4.5 x 3.0 x 2.9 cm. Amongst the fine cobaltoan calcites that have been coming from Bou Azzer have been just a few of these amazing shocking pink specimens, presumably from a higher concentration of cobalt, but whatever the case, the crystals just have this vivid saturation of color. These crystals are extremely gemmy and lustrous and reach 1.5 cm.
