5.7 x 5.1 x 3.3 cm. Another wonderful piece from the Elmwood Mine. This is a gemmy calcite twin, light golden color, perfectly set on a matrix of sphalerite with distinct crystals piled up underneath the twin.
7.5 x 5.6 x 4.8 cm. A powdering of glittery golden pyrite decorates the edges of these milky rhombohedrons of calcite from China.
9.7 x 9.2 x 6.6 cm. A large plate of the most prized calcite varietal, hot pink cobalt-rich crystals, here of good size as well (to one centimeter).
7.8 x 7.4 x 4.9 cm. A perfect 2.8-cm twin of calcite, transparent, symmetrical and pristine, perched at the edge of a matrix covered with tiny, gemmy, sparkling calcites.
11.9 x 7.8 x 3.4 cm. Starting early on, miners at this classic American locality began saving specimens of calcite, as they had no commercial value to the mining company, but were prized by miners for their great variety and beauty. Collector Dave Stoudt had calcites in a dizzying array of forms from Bisbee. This is a plate of milky crystals with extremely modified forms - so much so in fact that the form is hard to describe, though you can make out some rough rhombohedrons. Ex. Dave Stoudt Collection.
4.7 x 1.4 x 1.1 cm. A rare, old-time, doubly terminated calcite crystal from Frizington, England. This very showy miniature has pristine, complete all-around, gemmy, water-clear, complex terminations. The center is included with clay and the contact is behind the center.
5.6 x 3.3 x 2.7 cm. An aesthetic cluster of three, glassy, water-clear, purple fluorite cubes with excellent edge phantoms from Berbes, Spain. Crystals reach 2.6 cm and are nicely accented with glassy, colorless calcite crystals.
3.7 x 2.0 x 1.4 cm (largest). A beautiful, aesthetic and contrasting pair of spinel-twinned silver miniatures from the early 1980s finds at the New Nevada Mine at Batopilas, Mexico. The piece on the left is a solid matte of intricate, herringbone-patterned, silver crystals. The spinel-twins have a super patina, with iridescence. The classic specimen on the right features beautifully isolated silver "feathers" etched out of the enclosing snow-white calcite. The silvers also exhibit a nice patina with iridescence. A distinctive and excellent pair of Batopilas silvers.
Actually, funny enough, calcite is VERY rare at the Himalaya. This piece is very nice because it is associated with and highlighted by rich purple ledpidolite crystals. This was a piece I had obtained from an old County collection shortly after moving to SD in 1995, kept in my own calcite collection, and then sold to Chris a few years ago. 6.5 x 6 x 2.5 cm
8.9 x 5.4 x 5.1 cm. Most of these Chinese orpiments have a lot of damage (bruising), and they can be dull. But here, you have gemmy crystals of the most incredible candy luster. And, the crystals are elongated, slender and elegant in form (to 1.5 cm). The intergrowth of scalenohedral calcites with the orpiments adds a lot to the attractiveness of this superb orpiment specimen.
4.4 x 2.6 x 2.2 cm. Clay Center is best-known for its amber-colored cubes of fluorite, but here is a rather uncommon combination specimen from the locality: a complex, compound crystal of spiky calcite has grown on a spray of frosty celestine (this same form of celestine is often seen in association with the familiar fluorites from there).
6.1 x 5.3 x 4.0 cm. Lustrous, transparent crystals of calcite on a field of tiny fuzz-balls of grass-green malachite - the entire matrix here is spongy malachite in fact.
10.2 x 8.8 x 5.8 cm. An intact pocket of the most prized calcite varietal, hot pink cobalt-rich crystals, here of superb, gemmy clarity.
10.5 x 8.4 x 5.8 cm. This is a really fine (and large) specimen from a strange and beautiful find in China in 2006, of large calcite crystals with edges selectively "gilded" with bright golden pyrite. Some of the specimens had rather sparse pyrite, but here, it richly coats the crystal edges.
7.5 x 4.9 x 2.3 cm. A striking specimen with lustrous, pseudocubic, butterscotch-colored wulfenite crystals artfully scattered about and beautifully complimented by a rich sprinkling of white calcite rhombs from a new find at the Mina Ojuela at Mapimi, Mexico. The largest wulfenite crystal is 9 mm and calcite is uncommon from this find. The exact mine location is Level 6, San Juan Poniente vein. The gossan matrix has a nice sculptural quality to it and there are also a few scattered, translucent, apple-green mimetite botryoids.
