Calcite

19.0 x 17.2 x 9.8 cm. This is a superb example of Elmwood calcite: Rarely do you see such a large and gemmy doubly-terminated crystal with matrix, and in such condition. This hosts a doubly-terminated, twinned, gemmy crystal with a great cognac color, measuring 19 cm across. This crystal is beautifully perched on gray limestone matrix.

Limestone mineral

Limestone. Limestone forms by sedimentation, of coral and shells (biological limestone) or by the precipitation of calcium carbonate (as calcite and aragonite), in marine waters. It comes in many forms (e.g. chalk, coquina, fossiliferous, lithographic, oolitic, travertine, tufa). It can be crystalline, clastic, granular or massive.
