5.2 x 3.6 x 2.7 cm. The Camp Bird mine near Ouray, Colorado is one of the most classic of all the Colorado ore body localities. It is celebrated for its superb Chalcopyrite specimens, exhibiting some of the finest twins for the species extant. This specimen features a few superb, sharp, splendent, metallic, brassy-gold colored twinned crystals of Chalcopyrite which are associated with sharp, jet-black Sphalerite crystals sitting atop contrasting white, prismatic Quartz crystals. From the 600’ Stope, 2100’ Level. Ex. Richard Kosnar Collection.
A superb specimen from the exciting NEW finds at Las Vigas, with purple-blushed crystals to 3 cm. Two of the crystals had their termination grow together! 5.5 x 5.5 x 3 cm
Pretty blue color coming right through a druse of sparkly quartz. 3.8 x 3 x 1.3 cm
Bright, gemmy spessartines to 0.6 cm scattered across the matrix and amongst gemmy smoky crystals. The matrix has rises and recesses that make it quite sculptural and 3-dimensional vs. the usual flat plate. 11 x 8 x 4 cm
14.3 x 7.0 x 6.5 cm. A striking, very rare cabinet quartz specimen from Mariposa County, California. This giant crystal is a complete-all-around, doubly terminated floater. The glassy crystals are transparent to translucent. Two sides of the main crystal show inclusions of sparkly, brassy, pyrite microcrystals. The sidecar crystals, the unusual, notched, stepped-growth, basal termination and water-clear, main termination are super accents. Ex. F. Stevano Collection.
A dramatic and aesthetic specimen of a large, sharp, lightly etched, translucent and lustrous smoky quartz crystal jutting vertically off a matrix of spessartine-coated white albite. The gemmy orange to brown spessartines partially grow up the sides of the smoky. Displayed to best advantage, the small bits of damage atop the smoky termination is very much minimalized and it presents like a more expensivce specimen. 7.5 x 7.1 x 5.4 cm
Beautiful, highly lustrous, transparent to translucent zoned-green hexagonal uvite crystals to 1.0 cm aesthetically coat and grow off of a transparent to translucent colorless quartz crystal from the early 90s find at Brumado, Brazil. Pieces of this quality are seldom on the market. Pristine. 5.4 x 2.2 x 2.1 cm
8.4 x 5.5 x 5.3 cm. This is a rare classic. These little purple fluorites used to be (before Dal’negorsk) synonymous with the rare tetrahexahedral habit of fluorite and were much studied. This is an attractive matrix specimen with excellent pedigree and original labels dating it to the early 1900s. Jack purchased it about 5 years ago from Gene Schlepp. Ex. Jack Halpern Collection.
7.8 x 6.7 x 4.8 cm. I am really fond of this old fluorite from the venerated Heights Mine even though the crystals do not appear to be twinned in the "classic" manner you expect. The crystal is also rather large. The combination of drusy, white quartz surrounding the green, gemmy, well formed, 3.5 cm fluorite crystals is outstanding. They fluoresce somewhat, even in just daylight...in fact there is a hint of purplish-blue when viewing the fluorite through the side faces just in normal lighting. There is also a second generation of fluorite which has grown on the drusy quartz. Ex. Lindsay Greenbank Collection.
11.4 x 10.5 x 9.2 cm. Aesthetically situated in completely hollow basaltic vug, a diverging spray of gemmy, lustrous natrolite crystals to 6 cm in length emanate from a druse of sugary white quartz. Although a few natrolite crystals do span the vug and are attached to the ceiling, the majority are visibly terminated.
8.1 x 6.4 x 4.9 cm. Natrolite is a rather rare mineral from India. For symmetry and perfection, you will likely have to search a long time to find one as aesthetic as this 2.8 cm spray. The way the Natrolite delicately nestles among the Quartz crystals is simply marvelous.
12.1 x 9.2 x 4.5 cm. Nestled down in a basaltic vug is a most beautiful "puff ball" of Mesolite, undamaged and sharp. The stark white Mesolite, which measures 4.5 cm across, is actually composed of fine acicular crystals.
6.7 x 6.3 x 3.3 cm. This is a fine Peruvian rhodochrosite specimen, featuring sharp crystals of outstanding color and luster.
6 x 5.3 x 3.1 cm. Translucent, rich pink, rhombs of rhodochrosite, to 1 cm across, and colorless quartz crystals, to 1.5 cm in length, sit nicely on a matrix of massive quartz.
11.5 x 4.8 x 3.9 cm. A fine, doubly-terminated South African smoky quartz crystal. This crystal is striking for its extraordinary long termination, transparency and size. It is complete-all-around and the sidecar crystals are a super accent. Very interestingly, the tip of the long termination is very glassy, transparent and is nearly colorless, while the other termination harbors a very interesting phantom. The smoky quartz has good lustre, with gently striated faces. Very nearly pristine. These fine South African smoky quartz crystals show both wonderful clarity and gorgeous form - long, slender and elegant and rival Swiss smoky quartz.
