10.5 x 6.5 x 4.0 cm. An excellent Sweetwater calcite specimen from the Feist Collection. This superb crystal has beautiful "cut glass" modifications all over its highly lustrous faces. It shows unusual transparency for a Sweetwater calcite, and wonderful bright honey-golden color. At the base of the crystal are some smaller calcites, some galena crystals, and a bit of chalcopyrite.
This 385-gram speicmen is composed of a thick carpet of silver crystals, thickly covering and rising from a thin rock and calcite matrix. It is MUCH better in person as the size makes it hard to photo well and still cvapture any detail of the silver crystalization all over it; and it is truly a dramatic large silver specimen. The especially rich knob of silver crystals atop is complete all around, and the backside is almost as nice as the front in terms of display. These silvers came out a few years ago, maybe around 2000, from a contemporary mining venture near the classic old Kongsberg Mines. There was a bit of a scandal at the time involving a certain infamous European dealer widely known for such labeling "errors," who marketed these as "Kongsberg" material and dispersed a number of them to the market in this manner. They are not from Kongsberg, but they are still damned impressive and at a much cheaper price than their Kongsberg brethren would be, as well! 18 x 7 x 3 cm
3.3 x 3.1 x 2.5 cm. A limpid, amber-colored crystal of calcite, that flashes like fire internally under good light. The North Vernon calcites are a classic Midwestern material. This piece probably came out in the late 1990s. Ex. Consie Prince Collection.
14.9 x 13.9 x 4.9 cm. An other-worldly cluster of spiky stalactites (or stalagmites?) of calcite, rising parallel to one another. What is really interesting about this specimen is how the "base" formed at various levels, creating a sort of multi-tiered candelabra effect. This "base" is actually uncontacted; the only contact, in fact, is about an inch at the far right bottom. Ex. Ida and Henry Mullane Collection, assembled in the 1960s and 1970s.
9.0 x 6.5 x 5.6 cm. A huge crystal of purple fluorite from the Elmwood Mine. The display side of the crystal is complete, and the backside where it was once attached to the pocket wall demonstrates with its thousands of microfaces that it came loose in the pocket and then naturally healed - making it technically a floater now. In a way this is very fortunate, because it means that light can get to the back of the crystal so it can light up a rich purple under good light; had the crystal been a more entire cube, it would have been almost opaque except under the most intense light. Atop the crystal sits a calcite crystal of unusual form and color (colorless) for the mine, along with a bit of dolomite. A super-sharp phantom is visible inside when the crystal is viewed from the bottom, also quite unusual for the Elmwood. Ex. Consie Prince Collection.
4.5 x 4.4 x 2.6 cm. Splendent, thick tabular, "sandwich-style", caramel-colored wulfenite crystals richly and beautifully covered the 3-dimensional mounded matrix of calcite covered with vanadinite variety endlichite on this showy and excellent specimen from the famed Ahumada Mine at Los Lamentos, Mexico. Highly lustrous, "sandwich-style" wulfenites on white calcite are a classic and desirable wulfenite varietal from this very well-known locale. Crystals reach 9 mm. Ex. Karl Warning and Colonel Barron Collections.
5.8 x 5.1 x 3.5 cm. A 2.8 x 2.7 cm, lustrous, translucent, twinned, tan calcite crystal aesthetically dominates a field of smaller calcite rhombs on this fine specimen from an uncommon Eastern Colorado locality - La Junta, Otero County. The calcite rhombs are attached to an earlier generation of banded calcite. These calcites come from concretions in the Cretaceous-aged Pierre Shale. Ex. Karl Warning and Marty Zinn Collections.
9.5 x 6.0 x 3.6 cm. Lustrous, translucent, light gray calcite rhombs to 2.0 cm richly and attractively cover the chlorite schist matrix plate on this fine specimen from the NEAT tunnel workings in Canton Uri, Switzerland. The sparkly pyrite microcrystals are a very nice accent. Ex. Brent Lockhart Collection.
3.5 x 2.2 x 2.0 cm. Djurleite is an uncommon copper sulfide closely related to chalcocite. Two, sharp, opposing, moderately lustrous djurleite crystals to 1.6 cm are beautifully set on a matrix of flattened, colorless calcite scalenohedrons. The large calcite crystal is doubly terminated. Ex. Carl Davis Collection.
8.4 x 4.8 x 2.9 cm. A fine calcite specimen from recent finds at the Moscona Mine of Spain. Glassy, transparent, colorless, complex calcite rhombs cover this fine specimen. Part of the piece has tiny, lustrous, rhombohedral calcites in parallel stair-stepped growth, reminiscent of the calcites from the Blackstone Mine, Shullsburg, Wisconsin.
A highly unusual WIRE-like SILVER from Batopilas, in contrast to the more common form we see from historic finds there of sharp, elongated , spinel-twinned crystals. I say "wire-like" because on close inspection this IS the typical crystal form - though unusually thick around the twin center so that it looks wiry instead of crystallized from afar. The wire/crystal in this case is very thick and sturdy, and rises dramatically from calcite matrix. Nice mini! 3.8 x 2.2 x 1.5 cm
Two extremely sharp dioptase crystals to 1 cm in size, perched on contrasting crystal calcite matrix 3.3 x 2.3 x 1.3 cm
GEMMY, CLEAR, SHARP calcite twin that is just gorgeous - with a higher lustre and richer brilliance in person than you see here. The twinning plane is perfectly and symmetrically defined, and the terminations are capped by the rarer multiple-faced caps typical of old specimens from this mine. Contact on the bottom, otherwise complete and pristine all around 4.8 x 2.3 x 2.3 cm
WOW! This is a superb, gemmy red, 2 cm crystal that sits regally atop the apex of a doubly-terminated(!) and equally gemmy Calcite crystal! With a brilliant striated reflective effect that actually adds to the character of the crystal, this is all you have ever imagined a top Realgar miniature to be! 5.3 x 3.8 x 2.5 cm
11.5 x 7.4 x 4.8 cm. Pale pea-green prehnite has pseudomorphed an enormous, thin, platy crystal of calcite (in addition to a couple of attached smaller crystals). The green is more apparent in person - the camera had trouble picking up the color. You can see the sharp hexagonal form in all the crystals. A very unusual pseudomorph from South Africa. Ex. Richard Hauck Collection.
