Colorful and with a flowerlike form, this is an excellent Calcite from the famed Cavnic mine of Romania. Sharp scalenohedral crystals radiating in a spherical mass have been coated with small Pyrite crystals and have internal coloring perhaps from Hematite. The back of the mass is broken where it was removed but the front display side is quite fine and undamaged. Lots of impact and far better in person.
A delicate specimen in excellent condition with very pale pink (mangano) Calcites on a matrix of needle Quartz, lustrous Sphalerites and Pyrite. An attractive and nicely composed specimen from the great Madan deposits of Bulgaria. To my taste the Sulfide deposits of this region have produced the most esthetic examples of many species. This is a small but striking piece with quite remarkable slender Quartz that are decorated with tiny crystals of Sphalerite as well.
Mine 884, Leiping, Guiyang County, Chenzoh Prefecture
3.6 x 2.5 x 2.1 CM (small miniature/ large thumbnail (toenail))
A perfect toenail of incredible gem clear Calcite from the finds in 2000 in Leiping. This find was huge news in the mineral world because the Calcites were so much like the prized 18-19th century British specimens. This find too has been finished and these are already modern classics. Far better than the photos show -top luster, glass clear transparency and textbook perfect form. A tiny bit of Hematite is noted on the matrix.
Calcite- classic British
Bigrigg mine, West Cumberland Iron field
3.1 x 1.7 x 1.6 CM (small miniature/ large thumbnail (toenail))
A clear sharp single scalenohedron from the famed Bigrigg mine. From an older European collection this is at least 80 years old but likely much older. There is a number attached that could be removed if desired. Quite clean by naked eye but some contacts and rough bits found with magnification, all under 1mm. Not perfect but looks it, and not expensive as is often the case with these old
An exceptional specimen the most perfect, colorful and gemmy Calcite I have seen from the closed Rucks Pit fossil clam locality. From early finds at this now classic location, an ex Arkenstone specimen, the luster and transparency are hard to capture in a photo. A small amount of the original clamshell fossil forms the base of this piece, the crystals had grown inside the clam but are now exposed. Unlike most of the thousands of specimens from here this is in the top .001 percent!
SOLD Calcite -Shullsburg habit
stock #SOLD A-35-523
Shullsburg, Lafayette County
10.1 x 6.8 x 6.1 CM (cabinet)
Fantastic form with a gem clear "cap" crystal on the termination of the older scalenohedron. In fine condition as seen with only very minor rub spots that are very hard to spot. Even better in person this shows with textbook perfection the habit that became famed from this old locale. Displays well from all sides. These old specimens still turn up from time to time, this one is far better than most.
Calcite on Quartz (amethyst)
Mina Peregrina, Guanajuato
8.4 x 6.4 x 4.1 CM (cabinet)
Bright glassy clear crystals of light pink-violet Calcite perched on a contrasting amethyst matrix. Classic material from Guanajuato, this is quite eyecatching. In excellent condition, there is a single clean repair that is super hard to find, that needs to be mentioned. This keeps the price low yet this displays like it cost far more.
Calcite w. Hematite
Daye Iron Mine, Edong Mining District, Huangshi Prefecture
6.1 x 3 x 4.7 CM (cabinet)
Hematite included Calcite crystal with fine color, luster and an overall esthetic presentation. This is an unusual form twin that is completely differnet from any others I have seen from Daye. With well developed phantoms, this is in excellent undamaged condition.
