Calcite Geodes

Stone: Calcite
Size: 4.5"-6"

Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate. The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 3 as "calcite".  Calcite is thought to amplify thought, improve memory and intellectual capacity; promote mental growth and development.

A geode is a round rock which contains a hollow cavity lined with crystals. Rocks which are completely filled with small compact crystal formations such as agate, jasper or chalcedony are called nodules. The only difference between a geode and a nodule is that a geode has a hollow cavity, and a nodule is solid. Depending on the type of geode, they are rated between 6.5 and 7.5 on the Mohs hardness scale. Geodes are thought to improve intellectual insight, awareness and community spirit, as well as help to attract compatible friends and lovers.
