SOLD Calcite - classic USA
stock #SOLD 17.1-592
Minerva #1 Mine, Cave-in-Rock, Hardin County
Illinois, United States
8 x 6.8 x 4.7 CM (cabinet)
price: $0

Sharp and very esthetic clusters of tapered "flame" habit Calcite from the famed Minerva #1 Mine. These Calcite have elongated prisms that are almost needle-like at the terminations which are very slender and delicate. A classic of the southern Illinois Fluorite district, these are not often seen for sale. An important and unique style this is an excellent addition to a good Calcite or southern Illinois collection. The Calcites are all frosted with a white coating but below that they are a bright yellow-orange color. Some tips on the left side back are cleaved but nearly all the others are perfect. From logical display angles there is no visible damage and the condition is excellent for one of these delicate Calcites.

SOLD Calcite with Siderite
stock #SOLD AX-22-279
Mancos Shale, Montrose, Montrose County
Colorado, United States
6.2 x 4.8 x 4.2 CM (cabinet)
price: $0
Late Summer 2021

Well-defined Calcite rhomb crystals to 2.8CM across, on a contrasting Siderite matrix. The Siderite is botryoidal with a few isolated balls. In excellent condition as seen, the Calcite is fluorescent a good red color. Ex Frank Knaus and Dave Bunk, this is well above the usual quality for these Shale deposits, which we understand are either exhausted or off limits to collecting. A nice Colorado Calcite.

SOLD Calcite (Manganoan) radiating crystal sprays
stock #SOLD AX-12-245
Dalnegorsk, Kavalerovo Mining District
Primorsky Kray, Russia
7.8 x 5.6 x 3.6 CM (cabinet)
price: $0
Late Summer 2021

Light pink to apricot color Calcites in delicate strays of radiating, acicular crystals in a three dimensional sculpture. In excellent condition, this looks fine from every angle. Typical of these Calcites, this piece is vividly florescent. The specimen hosts two generations of Calcite, the smaller more recent crystals are a brownish color and give a nice contrast.

Calcite - old English
stock #21.1-288
Haile Moor Mine, Haile, Copeland
Cumbria, England
4.7 x 3.2 3.1 CM (miniature)
price: $390
Late Summer 2021

An esthetic cluster of glassy, translucent reddish- pink color Calcites from Cumbria, England. Old labels from the collection of Marie Osbonlighter and Robert Eaton are included. This Calcite is vividly Fluorescent. Most of the colorful Calcites from this region were found long ago the majority were colorless. The Haile Moor Mine is known to have produced some Calcites with Hematite inclusions that give a reddish color like this. An attractive miniature from most any point of view. Overall in fine condition though there is one cleave on a crystal that is visible at some angles (shown in these photos) but is clearly not distracting or easily noticed.

Calcite included by Chalcotrichite - USA classic
stock #20.1-907-(ZSCTR4098)
Campbell Shaft, Bisbee, Cochise County
Arizona, United States
8 x 5.9 x 5.7 CM (cabinet)
price: $1500
Late Summer 2021

An excellent and very colorful example of a Calcite with blood-red Cuprite (variety Chalcotrichite) included in Calcite crystals. Calcites from Bisbee were sometimes included by Copper minerals, often Malachite, and colored by these inclusions. This is a sizable example of this quite rare and prized red Calcite from the Campbell shaft at Bisbee. There are cleaved crystals at the outer edges but the main red Calcites are in good condition overall. The matrix is a solid ore and has a few areas of micro Cuprites on it as well. The Calcite crystals are up to about 1 CM. Most Bisbee minerals seen in displays are green or blue, bright red specimens are uncommon and really stand out. These old Calcites are just about never available except from the breakup of old collections.

Calcite (pineapple type) on Fluorite
stock #7.AE-426
Shangbao Pyrite Mine, Leiyang
Hunan Province, China
5 x 3.9 x 3.3 CM (miniature)
price: $240
Early summer 2021

The "pineapple" type Calcite from the Shangbao Mine were found in the 2004-7 era but not seen in more recent mining. These were mostly translucent to transparent and the color looks just like pineapple. This piece is a single doubly terminated crystal on etched Fluorite that is both light purple and blue. In good condition overall, there are some very small contact points and rough spots but no chipping or real damage. This is in remarkable shape for one of these as most have considerable damage. An attractive Shangbao specimen and a very good example of this very cool habit.

Calcite - curved saddle-form crystals
stock #21.1-226
Herja Mine, Chiuzbala , Baia Mare
Maramures, Romania
7.7 x 4.6 x 3.7 CM (cabinet)
price: $130
Early summer 2021

Sharp edged saddle shaped crystals of Calcite with curved or bent faces in a stacked cluster. The Calcites are a flattened rhomb habit with every face showing the curved plane but most strongly visible on the largest crystals. The Calcites are a very light grey color and in good condition, some minor edge roughness exists and most of the Calcite has a matte luster on the surface that looks textured but several parts also have a brighter smooth surface as well. An odd habit that is a lot like saddle-shaped curved Dolomite but this form is not at all common in Calcite.

Calcite on Hemimorphite
stock #AX-12-178
Santa Eulalia, Aquiles Serdan
Chihuahua, Mexico
11.6 x 2.3 x 2.3 CM (cabinet)
price: $1100
Early summer 2021

A most unusual form and combination. This transparent to translucent Calcite crystal is gemmy and twinned. It is perched on a finger-like shaft, covered with hundred of tiny Hemimorphite blades and also small Calcite crystals. The association and form of this structure is very odd; this was found in the 1970's. The Calcite is complete except for a cleave on the back left side that is not seen on display. Due to that cleave this is not a specimen for the ultra perfectionists, but is incredible for the locality and a very choice display piece presenting an exotic form.
