9.0 x 8.8 x 0.5 cm. A fantastic and historic slabbed specimen of Gold (var "Electrum") from the famous Idarado mine (650 Level, Tomboy Vein). The Gold has a lustrous, bright, metallic appearance, and stands out beautifully against the snow-white Quartz and black Sphalerite matrix. It was collected by Andy Sutyak of Ouray, Colorado in 1927. The piece later went to Clancy Fleetwood (Brian Kosnar's great-grandfather), and in 1984 became part of the famous Colorado mineral collection of Richard Kosnar, whose hand-painted catalogue number (G1084Tb) is on the bottom of the specimen. Ex. Richard Kosnar Collection.
5.3 x 3.5 x 2.3 cm. Russian citrine specimens are very difficult to come by. This is a dramatic and beautiful, complete-all-around cluster. The crystals are very gemmy, with the beautiful and distinctive golden-yellow color peculiar to the best Russian citrines. From a small find of 3-4 years ago (2006-2007). Ex. Jesse Fisher and Joan Kureczka Collection.
2.0 x 1.7 x 1.3 cm. Lustrous, translucent, light cherry-red rhodochrosite rhombs are strikingly attached to a cluster of water-clear quartz needles on this exquisite thumbnail from the famous Hedgehog Pocket of the Sweet Home Mine.
7.3 x 6.2 x 4.8 cm. Moderately lustrous and lightly iridescent, charcoal-gray bornite crystals (to about 1.5 cm) are very well-placed amongst sharp, water-clear quartz crystals on this excellent, combination, old-time specimen from the famous mines at Butte. Classic and very showy material, with the quartz spikes as perches for bornite…not as ugly as most from here. Ex. Robert Whitmore Collection.
11.6 x 4.7 x 3.6 cm. An outstanding, classic, cabinet, combination specimen from the Panasqueira Mine of Portugal. Very glassy, pearlescent, hexagonal apatite crystals to 2.8 cm, are strikingly set on the side of a complete-all-around, lightly frosted quartz crystal. Tiny marcasite crystals are embedded on and included in both the quartz crystal and the apatite crystals. The striking combination piece is essentially pristine. The apatite crystals are pristine and the three, flat-lying crystals are doubly terminated.
15.4 x 8.0 x 4.1 cm. An impressive and aesthetic, large cabinet plate studded with glassy, water-clear amethyst crystals from the famous deposits at Piedra Parada, Mexico. The highly lustrous crystals have very pleasing purple color and reach 3.0 cm. The amethyst crystals rest on a bed of small quartz crystals infused with tiny epidote blades. Nearly pristine. Ex. Franz Saller Collection, of Bavaria.
11.4 x 7.5 x 3.8 cm. A seldom-seen, classic and very fine cabinet combination plate from the historic mines at Trepca. Snow-white balls of tiny, glassy siderite crystals richly and aesthetically cover the sculptural specimen of brassy pyrite pyritohedrons, dark gray arsenopyrite crystals and a small forest of quartz crystals. Throw in a few, colorless, poker-chip calcite crystals and you have an outstanding combination piece from this famous locale. Ex. Franz Saller Collection.
11.5 x 10.5 x 4.0 cm. Lustrous, translucent, zoned, purple fluorite cubes to 2.2 cm are richly and aesthetically strewn on the cabinet matrix plate covered with sparkly drusy quartz from recent finds at the Shangbao Mine of China.
8.4 x 6.8 x 4.1 cm. A very aesthetic specimen of moderately lustrous, intergrown hematite "iron roses" strikingly studded with quartz crystals to 2.6 cm from recent finds at the Lechang Mine of China. Fine combination material from this locale.
18.2 x 17.0 x 7.5 cm. Our Chinese sources have furnished us with another striking example of the mineral bounty of their country. This is a new find of carved and polished jasper picture stone from a less well-known area. This striking, two-sided, large cabinet piece has two outdoor, country scenes of sparsely covered, wooded hillsides below a grayish sky. They look like paintings from Chinese murals or room dividers. Art in stone. The measurements include the custom-made wooden base. Weighs 7.3 pounds or 3.3 kilograms.
12.2 x 11.8 x 9.4 cm. A very fine and highly unusual pseudomorph from the famous basalt flows of Irai, Brazil. Sparkly, purple to brownish-purple amethyst has pseudomorphed (casted) a very large, 9.5 cm, hexagonal, poker-chip calcite crystal. Smaller pseudomorphs add character to this dramatic piece, which is hollow and lightweight for its size. Rare, large size for this material, unusual in its good condition. Ex. Robert Nowakowski Collection.
18.0 x 12.9 x 11.1 cm. Pearlescent, pastel-pink stilbite blades and apophyllite crystals are aesthetically set on this impressive, large cabinet combination specimen covered with interesting, rice grain-like, drusy quartz from recent finds at Jalgaon. This very well-prepared, mounded, two-sided piece is highlighted by the 7.7 cm stilbite bowtie and the 4.5 cm, doubly terminated, bi-colored apophyllite crystal beautifully set on the crest of the specimen.
10.5 x 9.5 x 6.0 cm. Striking clusters of pretty, pastel-purple, lightly frosted, lustrous and translucent amethyst crystals are very aesthetically scattered on the cabinet matrix plate covered with brilliant, brass-yellow, striated, pyrite pyritohedrons and iridescent, brassy chalcopyrite crystals. The amethyst crystals reach 5.0 cm - rare for this locality. This is a pristine, classic and beautiful, large combination specimen from the famous mines at Cavnic, Romania. Very little new material is coming from these historic mines. Ex. Brent Lockhart Collection.
6.9 x 5.7 x 4.8 cm. This is a colorful cluster of nearly massive dioptase, with admixed cerussite as well. From it spike out gem, elongated dioptase crystals to 2.1 cm. This is one of the few matrix specimens of this crystal style recovered from the mine as yet and who can say whether more will come? This habit of elongated crystals, in such gemminess, is really quite new, and beautiful. The important crystal is not damaged, despite its freestanding nature. It is partially coated on the backside by quartz, which helped to protect it. Ex. Charlie Key.
8.6 x 7.3 x 6.2 cm. Deep green crystals, some doubly-terminated, here reach about 1.5 cm and are clustered richly on quartz matrix. This specimen is pristine, except only for a few trivial peripheral crystals to the left or bottom depending on how it’s displayed. It looks good horizontal, and vertical both. The crystals are sharp and 3-dimensional and "pop" out at you - looking for all-the-world as if they were glued onto the quartz matrix, because they are so remarkably freestanding. A superb specimen. When shipped to us, it was a protected pocket, from which this was trimmed out carefully. Ex. Charlie Key.
