C-330 Calcite
with Celestite Sylvania Minerals Quarry, South Rockwood, Monroe County, MI 11.1 x 6.5 x 5 cm A matrix specimen of honey-yellow Calcite crystals with white Celestite crystals. The Calcite crystals are mostly transparent and undamaged. Both the Celestite and the Calcite exhibit moderate fluorescence. The very tips of the Calcite fluoresce yellow-white, while the Celestite has white fluorescent overgrowths.
C-244 Calcite
with Hematite Santa Eulalia District, Municipio de Aquiles Serdán, Chihuahua, Mexico 7.5 x 4.6 x 4.7 cm This is a type of Calcite that came out a long, long time ago from Santa Eulalia and has been unavailable - until a recent find in 2007. These Calcites are instantly recognizable by their strange form: an earlier generation of dark, opaque, hematite-included scalenohedral crystals seeming to emerge from within a later generation of translucent crystals of a lighter color. This specimen is undamaged and is from the original find.
F-184 Fluorite
with Calcite, Quartz and Pyrite El Hammam Mine, Khémisset Province, Rabat-Salé-Kénitra Region, Morocco 15.5 x 14.5 x 4.1 cm This specimen features many medium to dark-green crystals of Fluorite. This specimen has several interesting features; the first being numerous water-clear Quartz crystals up to 3 mm. in size that cover the entire specimen. The top of the specimen is blanketed with Calcite and there are dozens of brass-colored, ball-like Pyrites covering the specimen. This Fluorite specimen is complete, with no damage. The back of the specimen is flat , but shows many growth hillocks as well as many white, needle-like inclusions. A good example of a combo specimen for this location.
C-227 Calcite
on Celestite Stoneco White Rock Quarry, Clay Center, Ottawa County, OH 6.5 x 6.3 x 3.9 cm A cluster of lustrous, light-yellow, scalenohedral Calcite crystals, some of which are double-terminated on a matrix that is sprinkled with many millimeter-sized crystals of Celestite. The Calcites are translucent and all are undamaged. Uncommon material from a mine that is better known for its Fluorite And Celestite specimens.
C-277 Calcite Hilton Deposit, Borrego Springs, San Diego County, CA 29 x 17.3 x 11.5 cm A dramatic and huge plate of large Calcite crystals of from south-eastern San Diego County. This impressive specimen features translucent-transparent, bladed crystals of Calcite measuring up to 10 centimeters in size. The Calcite crystals fluoresce a light-hued red\pink color. Known by locals as "The Calcite Mine" this location was operated from 1942 to 1944 for the Polaroid Corporation to produce optic grade Calcite in order to make the Polaroid Optical Ring Gun-sight. This specimen was a part of my award winning mineral collection and was judged best specimen from San Diego County and won the prestigious Josephine Scripps award in the mineral competition at the San Diego County Fair where there is some serious competition from local "heavy-weight" type mineral collectors. This location has been off-limits to collectors since 1974 when the area surrounding it was designated Anza-Borrego Desert State Park.
AD-223 Calcite
& Quartz geode (fluorescent) Juchem Quarry, Niederwörresbach, Birkenfeld, Rhineland-Palatinate, Germany 12 x 9.5 x 6.8 cm A very large geode lined with tiny crystals of Quartz upon which rest many golden to red-colored, Hematite included, crystals of Calcite. Rare, old material.
AD-072 Calcite
Geode St. Francisville, Clark County, Missouri 9 x 6 x 4 cm A showy specimen of translucent and lustrous Calcite crystals inside of a Quartz-lined Geode. This specimen is from an obscure location and is older material that is not often seen for sale.
AD-147 Calcite
geode Bou Azzer District, Tazenakht, Ouarzazate Province, Drâa-Tafilalet Region, Morocco 9.5 x 4.7 x 7.2 cm A geode filled with many lustrous and clear crystals of Calcite measuring up to 1.7 centimeters in size. If you examined, in person, the matrix that these occur in, you'd be surprised that they can be extracted more or less intact.
C-123 Calcite on Siderite SOLD Turt Mine, Satu Mare, Maramures, Romania 7 x 6.5 x 3 cm A very interesting specimen from a well-known Romanian mineral location. This specimen features a 2 x 2 cm. crystal of Siderite that has replaced the mineral Calcite, with many smaller sphere-shaped stacks of Siderite, upon which sit numerous clusters of Calcite exhibiting the same peculiar habit.
F-251 Fluorite with Quartz SOLD Taolin Mine, Linxiang County, Yueyang, Hunan, China 5.8 x 5 x 3.7 cm This peculiar Fluorite specimen is from a find made about 12-14 years ago. This light-green Fluorite is a lightly etched and is topped with a cuboctahedron. It is coated on one side with small crystals of Quartz. An unusual specimen from a lesser known Chinese Fluorite locality. |
