3.8 x 2.9 x 1.8 cm. A rare, spinel-twinned fluorite crystal perched atop a zig-zag cluster of tan calcite crystals from the Naica Mine which has finally been productive again of late. A 1.7 cm much flattened, gemmy and lustrous, lavender fluorite crystal crowns this fine miniature. A striking, 1.5 cm, doubly terminated calcite crystal rests at the base of the spinel-twin.
9.2 x 7.5 x 4.0 cm. A superb specimen of manganoan calcite. The beautiful hemisphere is covered with sharp, lustrous and translucent, lightly frosted, manganoan calcite scalenohedrons. Excellent orange fluorescence. Manganoan calcite scalenohedrons of this quality and style were very uncommon from the Kalahari Manganese Field. This excellent specimen certainly dates to the 1960s-70s, as evidenced by the style of the 3 accompanying labels. Ex. Mullane Collection.
6.5 x 6.2 x 4.5 cm. A superb specimen from the Verchniy Mine at Dalnegorsk. A beautiful and pristine, 6.0 cm, doubly terminated, transparent to translucent, glassy calcite crystal is beautifully set upright on quartz-rich matrix covered with a multitude of smaller calcite crystals. The basal termination has a striking sawtooth pattern. This gem-like calcite crystal is complete-all-around. Ex. Karl Warning Collection and purchased from Russian dealer Yuri Pavel in 2006 at the Denver Show.
4.1 x 3.9 x 2.9 cm. A glistening, silvery cube of galena with a calcite scalenohedron slanting across one of its faces, from Missouri. Note the natural bevels on the galena corners. If you look closely, you will see rough galena crystals modified to flat-topped octahedrons on this specimen.
7.9 x 5.9 x 4.9 cm. From a new find in China at the ever-exciting Daye locality - a cluster of orangey-tan stilbite "bowties" intergrown with super-gemmy, lustrous scalenohedrons of calcite.
6.8 x 6.6 x 3.8 cm. This is a well-preserved cluster of caramel-colored, lustrous calcite crystals, sharp and with fine terminations. Calcites of great variety were saved from the very early days at Bisbee, being recognized for their beauty and variety by the miners, who were allowed to keep them since they had no commercial value. Ex. Jaime Bird Collection.
5.8 x 4.4 x 1.8 cm. The Magma Mine is best known for its barytes, but here is a very unusual and very pretty calcite from the locality. The crystals have a truly unique craggy form to them, highest in the center and tiered around the sides. They have a wonderful translucency and shimmer to them, as well. Ex. Jaime Bird Collection.
11.2 x 10.4 x 4.8 cm. The astounding color of this cluster of calcites results from rich inclusions of hematite, which you can see as a coating providing a flat, opaque setting surrounding the highly lustrous crystals themselves. Fortunately, there is no coating to mar the super sheen of the faces of the calcites - the hematite is all included inside the crystals.
4.4 x 4.2 x 2.6 cm. A gorgeous burst of pastel-pink calcite, with a bit of attached quartz and sphalerite, from Casapalca. The extreme spikiness of the crystals gives them an almost fuzzy appearance. Pretty from all sides, a 3-dimensional specimen with the crystals shooting out in all directions.
7.9 x 4.8 x 3.1 cm. A carpet of mossy-green conichalcite from Mexico - actually with small, translucent scalenohedral crystals if you look closely in addition to brushy patches. Conichalcite (Calcium Copper Arsenate Hydroxide) forms in the oxidation zone of copper ore bodies; the best-known specimens are from Mexico. This is a superb example of this find and style. Ex. Consie Prince Collection.
10.9 x 6.8 x 4.8 cm. A beautiful plate of frosty lavender octahedra of fluorite with gemmy centers, associated with light tan scalenohedrons of calcite. This is older material from Naica, as you can tell by the style. The faces are intricate with stepped micro-faces.
11.5 x 8.9 x 4.8 cm. A druse of sparkly quartz covers a large cluster of calcite scalenohedra, and, at the edge, a series of globes of green malachite. The entire specimen sparkles wildly from a sugary covering of quartz. Ex. Consie Prince Collection.
7.0 x 7.0 x 3.8 cm. A showy and excellent two-sided specimen from the Cassandra Mine of Greece. Both sides of the sulfide matrix are covered with vivid, pastel-pink pseudomorphs of rhodochrosite after blocky rhombs of calcite. The large, skeletal rhomb is striking and measures 4.0 cm across. The overall specimen is in excellent condition. Rarely available, classic material from this well-known locale. Ex. Jaime Bird Collection.
14.0 x 10.5 x 6.7 cm. A superb Chinese cabinet specimen from recent finds at the Xinxin Mine, Leiping, Hunan Province. A 14.0 cm doubly terminated, twinned, very glassy and lustrous, pastel-pink/mauve/light gray, manganoan calcite crystal is aesthetically displayed on a sliver of matrix nicely accented with smaller calcite crystals. This striking specimen has a deep twinning plane visible on three faces of the crystal and the crystal faces are wonderfully striated. There is a contact on the front, but there is not damage, per se. The freestanding termination is complete all-around and is pristine. Part of the back is contacted.
13.0 x 9.6 x 7.3 cm. This very large China rhodochrosite specimen has huge crystals to 5.25 cm, perched on contrasting matrix of quartz. The matrix also has pyrites and manganoan calcites speckled about for contrast. This is a large piece, impressive in display, and very colorful.
