Often calcite is the gangue mineral, or worthless part, of ore rocks. But clear pieces like this "Iceland spar" specimen are less common. Iceland spar is named after classic occurrences in Iceland, where fine calcite specimens can be found as big as your head. This is not a true crystal, but a cleavage fragment. Calcite is said to have rhombohedral cleavage, because each of its faces is a ...
Like many minerals, calcite comes in a variety of colors. Although it is tough to see in the photo, each of these pieces forms a rhombohedron. No cubes allowed! Although it is tough to see in the photo, each of these pieces forms a rhombohedron.
Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO 3). The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 3 as "calcite".

Calcite: from the 2013 Tucson Gem & Mineral Show (photo by Renate Surh). Its amazing how such unbelievable shapes and textures can be created by nature. This mineral is so unique and looks feminine due to the minerals that resemble flowers
This Calcite crystal is much clearer than the photos lead you to believe. This golden-yellow Calcite sits proudly in a nest of Galena crystals with the odd millimeter or so-sized Chalcopyrite thrown in for good measure. This specimen's termination is intact. A excellent example of Viburnum Trend Calcite.

Calcite, the more common mineral, forms in trigonal crystals, whereas Aragonite forms orthorhombic crystals. On occasion, crystals of Aragonite and Calcite are too small to be individually determined, and it is only possible to distinguish these two minerals with optical or x-ray testing.

Calcite is a rock-forming mineral with a chemical formula of CaCO 3. It is extremely common and found throughout the world in sedimentary, metamorphic, and igneous rocks. Some geologists consider it to be a "ubiquitous mineral" - one that is found everywhere.
Calcite is the one of the most common minerals. It occurs in a great variety of shapes and colors, and it constitutes a major portion of many of the earth's rocks.
