Calcite from Leiping Mine, Leiping, Guiyang Co., Chenzhou Prefecture, Hunan Province, China [db_pics/mdpics/MD-118808a.jpg]

11.7 x 7.3 x 5.8 cm. This is one of the last remaining specimens of a small stash we acquired from a recent find at the Leiping Mine in China. These calcites are unique and pretty in many ways. For one thing, they stand in total relief on the matrix, as if just sitting on it rather than being embedded at all. They also have a beautiful red-orange tone from inclusions of hematite. They have sharp faces, and are complete, undamaged and un-contacted all around. The largest crystal here measures 5 cm.


MD-118809 - Calcite (Var: Cobaltoan Calcite) - - Archived
Bou Azzer, Bou Azzer District, Tazenakht, Ouarzazate Province, Souss-Massa-Draâ Region, Morocco

Calcite (Var: Cobaltoan Calcite) from Bou Azzer, Bou Azzer District, Tazenakht, Ouarzazate Province, Souss-Massa-Draâ Region, Morocco [db_pics/mdpics/MD-118809a.jpg]

6.9 x 4.7 x 3.6 cm. These beautiful pink crystals have always been prized, and these recent specimens have BIG, GEMMY crystals with excellent color! The crystals here measure to over one centimeter, and are WONDERFULLY gemmy and bright! Cobaltoan calcite is most often seen as a druse, and it’s very hard to get with big, gemmy crystals like these!


MD-118815 - Andradite, Hematite, Calcite - - Archived
Wessels Mine (Wessel's Mine), Hotazel, Kalahari manganese fields, Northern Cape Province, South Africa

Rhodonite, Calcite from Franklin Mine, Franklin, Franklin Mining District, Sussex Co., New Jersey, USA [db_pics/mdpics/MD-118944a.jpg]

10.6 x 6.8 x 4.3 cm. An IMPRESSIVE CABINET specimen richly covered with large, blocky, pastel-pink rhodonite crystals on calcite matrix. This is CLASSIC, OLD-TIME material from the famous Franklin Mine. SELDOM do you see Franklin specimens with as many sharp rhodonite crystals. This piece is nicely assembled, with the largest crystal, 3.1 cm, featured at the top of the crystal cluster. SUPER orange fluorescence on the calcite. Ex. George Elling Collection.


MD-119111 - Baryte, Calcite - - Archived
Stoneham, Weld Co., Colorado, USA

Baryte, Calcite from Stoneham, Weld Co., Colorado, USA [db_pics/mdpics/MD-119111a.jpg]

9 x 7.3 x 4 cm. First-rate specimen of lovely sky-blue Barytes from the famous Stoneham locality. The Barytes have excellent luster, and are gemmy to translucent. The largest blade is an amazing 6.7 cm long and 1.2 cm thick. The attractive sky-blue color contrasts nicely with the tan Quartz matrix. From early 1980s mining. Ex. Steve Smale Collection.


MD-119113 - Calcite - - Archived

Calcite from Sarbaiskoe deposit (Sarbai; Sarbay Mine), Qostaney Oblysy (Kostanai [Kustany] Oblast'), Kazakhstan [db_pics/mdpics/MD-119113b.jpg]

10 x 6.7 x 4 cm. Large cluster of clear to gemmy-tan Calcites, ranging in size from .5 cm to 5 cm. The luster is excellent, and some of the Calcites do exhibit finely-stepped faces. The light orange fluorescence is very attractive. A good Calcite from a very well-known locality. Ex. Steve Smale Collection.


MD-119124 - Calcite, Jamesonite - - Archived
Herja Mine (Kisbánya), Baia Mare (Nagybánya), Maramures Co., Romania

Calcite, Jamesonite from Herja Mine (Kisbánya), Baia Mare (Nagybánya), Maramures Co., Romania [db_pics/mdpics/MD-119124a.jpg]

3.9 x 3.0 x 2.3 cm. A perfect dome of calcite, tinted a beautiful dove-grey by inclusions of jamesonite - from Romania. These sometimes also take the form of aggregates of bladed crystals from different pockets at the same locality. Quite a unique calcite form and color that you do not see from anywhere else! These were once common in the early 90s, not so now.


MD-119136 - Siderite, Calcite - - Archived
Nikolaevskiy Mine, Dal'negorsk (Dalnegorsk; Tetyukhe; Tjetjuche; Tetjuche), Primorskiy Kray, Far-Eastern Region, Russia

miniature, 4.1 x 3.4 x 3.4 cm.

Siderite, Calcite from Nikolaevskiy Mine, Dal'negorsk (Dalnegorsk; Tetyukhe; Tjetjuche; Tetjuche), Primorskiy Kray, Far-Eastern Region, Russia [db_pics/mdpics/MD-119136a.jpg]

4.1 x 3.4 x 3.4 cm. This is a perfect sphere of siderite from Dalnegorsk - no flat areas, dings or contact, it really is perfect - and the trim job is perfect too, so it sits on just the right amount of matrix. Siderite is typically an accessory mineral on mineral specimen, infrequently remarkable enough to compose a specimen in and of itself - but this is certainly an exception!


MD-119139 - Calcite - - Archived
Dongposhan Mine (Dongpo Mine), Dongpo ore field, Yizhang Co., Chenzhou Prefecture, Hunan Province, China

Calcite from Dongposhan Mine (Dongpo Mine), Dongpo ore field, Yizhang Co., Chenzhou Prefecture, Hunan Province, China [db_pics/mdpics/MD-119139a.jpg]

18.0 x 9.1 x 8.1 cm. The form of these Dong Po calcites is truly magnificent - glossy, flattened pyramidal calcites stacked up in towers teetering in every direction. There is no damage at all on this LARGE specimen. It glistens in even dull light and actually fluoresces a pretty pink. This is a large, truly eye-catching mineral specimen!


MD-119161 - Calcite, Pyrite - - Archived
Dachang Sn-polymetallic ore field, Nandan Co., Hechi Prefecture, Guangxi Zhuang Autonomous Region, China

Calcite, Pyrite from Dachang Sn-polymetallic ore field, Nandan Co., Hechi Prefecture, Guangxi Zhuang Autonomous Region, China [db_pics/mdpics/MD-119161a.jpg]

10.8 x 7.2 x 3.1 cm. Look at the bizarre structure of these calcite crystals - with their outlines defined by a strip of microcrystalline, sparkly pyrite! This find, which has produced sporadically over the past year, has also produced complete rhombs and clusters of rhombs. VERY unusual!


MD-119171 - Pyrite, Pyrrhotite, Rhodochrosite, Calcite, Galena, Sphalerite - - Archived

6.8 x 5.5 x 4.7 cm. A VERY SHOWY and CLASSIC combination piece from the ancient and famous Stari Trg Mine at Trepca, Serbia. This pristine specimen consists of two, intersecting, rosette-like discs. The fronts are covered with the famous bright, brassy pyrite pseudomorphs after pyrrhotite crystals and are beautifully accented by: WHITE botryoidal rhodochrosite in the middle of the front rosette; lustrous and colorless nail-head calcite crystals; lustrous, gray galena cubes on both rosettes; and lustrous, black sphalerite crystals on the back rosette. The backs of both discs are covered with white, drusy quartz. This is really a neat sulfide specimen with nice association minerals from a classic locality. Ex. George Elling Collection.


MD-119176 - Calcite - - Archived
Wyndham Mines, Bigrigg, West Cumberland Iron Field, North and Western Region (Cumberland), Cumbria, England, UK

small cabinet, 9.0 x 7.3 x 2.5 cm.
share specimen

Calcite from Wyndham Mines, Bigrigg, West Cumberland Iron Field, North and Western Region (Cumberland), Cumbria, England, UK [db_pics/mdpics/MD-119176a.jpg]

9.0 x 7.3 x 2.5 cm. A TOTALLY PRISTINE, SUPERB matrix plate covered with glassy, water-clear calcite scalenohedrons to 3.0 cm from the Wyndham Mine, Egremont, England. It is incredible, that there are no dings or broken crystals, except for along the periphery! The longest crystal is flat-lying. The calcites have less-common, modified terminations, with more faces, and many are preferentially dusted with tiny microcrystals of siderite or hematite? This is a CLASSIC English calcite in outstanding condition. Ex. Ed Ruggiero Collection, who purchased this superb piece from English dealer Richard Barstow in 1976. According to Ed’s card, the piece was mined in the 1930s and came from a miner’s collection.


MD-119184 - Fluorite, Calcite - - Archived

Fluorite, Calcite from Naica, Mun. de Saucillo, Chihuahua, Mexico [db_pics/mdpics/MD-119184a.jpg]

10.4 x 8.4 x 5.5 cm. This is an OLD-TIMER from Naica - a cluster of transparent fluorite cubes and modified cubes on a base of pink calcite! The fluorites measure up to 2.8 cm across their faces. It is interesting to see that one of the fluorites, for whatever reason, grew in a pseudo-triangular form with beveled corners, right amongst all the cubes! Ex. Gary Hansen collection.


MD-119326 - Calcite - - Archived
Nandan Co., Hechi Prefecture, Guangxi Zhuang Autonomous Region, China

large cabinet, 16.6 x 11.5 x 4.0 cm.
share specimen

CLICK HERE FOR LARGER IMAGE:
Calcite from Nandan Co., Hechi Prefecture, Guangxi Zhuang Autonomous Region, China [db_pics/mdpics/MD-119326a.jpg]

16.6 x 11.5 x 4.0 cm. This was a very small find about six months ago, and a VERY distinctive one. These calcites look like no other. They sit up on the thin crusts of matrix as if dropped there; they have a smooth, lustrous surface, and get their orange color from inclusions of hematite.
