Blue Calcite is a calcium carbonate mineral. It has a rhombohedral crystal system and a hardness of 3. It is mostly found in Mexico and deeper coloured specimens can be found in South Africa.
Metaphysically, blue Calcite is said to enhance psychic abilities, aid astral travel and soothe the emotional body. It provides a gentle cacoon of blue spiritual light, allowing one to gently float out of their body and into a dream state or into the domain of astral travel. Whilst astral travelling it can block out negative or unpleasant energies. It can open the inner avenues for conscious exploration of unconscious realms, from where most of one's creative ideas come from. Blue Calcite stimulates the throat chakra and can enable one to better express the insights recieved through inner exploration in the form of words, art or music.
