Calcite, rhombohedral and zoned, same location. 9.5 cm X 10 cm. This is an example of the calcite that coats the walls, ceiling, and floor of the Crystal Cavern. The Terlingua Mercury District is characterized by breccia pipes, collapse breccias that formed just a big jumble of limestone boulders. Caves are not uncommon in the mines of the district. Lots of open cavities means good collecting. (Author: Ed Huskinson)

"Wheat sheave" shaped white Calcites to 32 x 16 mm, with pearly luster and light-red Hematite accents are perched on sparkly contrasting matrix of Calcite. Although there is some damage, this is a very rare and important specimen-one of only three Calcites found at the Flambeau Mine in Wisconsin, and the very best one found. It was collected by Casey Jones who sold it to F. John Barlow (#5972), and was later consigned to Casey upon dissolution of the Barlow collection. (Author: GneissWare)

Gallatin Canyon, Montana, USA
17 X 10 X 6 cm
This is a fine, classic Gallatin Canyon calcite specimen. It is nearly a floater, I can find only two 1-cm points of attachment from what must have been a large pocket with branching, lobular matrices in it, covered with tiny calcites. On top of those grew the large golden scalenohedrons. The largest calcite is 7.5 cm (3 inches) and is doubly terminated. All the large scalenohedrons are undamaged. The overall size of this grand specimen is 17 X 10 X 6 cm. The specimen was passed from Ronald L. Anderson of Littleton, CO to the Buckskin Booksellers of Ouray, CO. I purchased in from Robert Stouffer, also of Ouray, CO. (Author: John Nash)

Calcite and goethite
Blaengwynlais Quarry, Bwlch-y-cwm, Cardiff, Wales, UK
Goethite pseudomorphing a 20mm pyrite crystal grown on a somewhat weathered calcite crystal. The goethite, clearly contemporaneous with the calcite, is loose within the cavity and can be removed and replaced.
Having seen and collected numerous goethite pseudomorphs from Blaengwynlais Quarry, I have never seen a remotely similar specimen from this location. (Author: ian jones)

Calcite in laumontite
Near Beaver Bay, Lake County, Minnesota, USA
25 X 18 X 16 cm
Ex-Roland Quinn, proprietor of the Beaver Bay Agate Shop at the time. Roland inherited the shop and collection from his father. This incredible specimen has a group of flat-topped pseudohexagonal calcites in a large boulder of calcite and laumontite. It clearly was a piece of a large calcite vein that broke off. The miracle is that the whole specimen looks like a water-worn rock, but the calcite crystals are pristine and undamaged, showing no signs of wear at all. Greg theorizes this must have been in a part of Lake Superior with a sandy bottom. The usual pebble bottoms would have made short work of the calcite. The largest crystal is about 6 cm across. A true Minnesota classic, rare beyond rare. (Author: John Nash)
