Check out the details on the great golden calcite specimen!  The two main crystals form a rare "v" shape, with good color and luster.   Perched well and isolated on the matrix.  It's a great collectors piece.
 
From the Sweetwater Mine, Missouri.  As with all of our minerals, no two pieces are alike, offering a truly one-of-a-kind gift for mineral collectors, Minecraft fans, geologists, and rockhounds alike.
 
Specimen is shown on our small Adjustable Mineral Stand.
 
Calcite is a popular collectible mineral cherished for its diverse crystal habits, vibrant colors, and widespread occurrence.  Calcite is a common mineral found in sedimentary, metamorphic, and igneous rocks worldwide.  It crystallizes in the trigonal crystal system, forming rhombohedral or scalenohedral crystals with three cleavage planes that are often visible.
 
Calcite is a major component of limestone, marble, and chalk, as well as many other sedimentary rocks. It also forms in hydrothermal veins, as a precipitate from groundwater, and as a component of some igneous rocks.  Calcite has numerous industrial applications, including as a building material (limestone and marble), in the production of lime and cement, as a soil conditioner, in the manufacture of glass and ceramics, and as a source of calcium carbonate in dietary supplements.
