Calcite

Calcite is a powerful amplifier and cleanser of energy. It’s said simply having Calcite in the room cleans negative energies from the environment and heightens your energy. Within the body, it may remove stagnant energy. The spectrum of colours cleans the physical and subtle bodies.
Psychologically, Calcite is said to connect the emotion with the intellect, creating emotional intelligence. Calcite may have a positive effect, especially where someone has lost hope or motivation. It may combat laziness, aiding in becoming more energetic on all levels.
Mentally, Calcite is said to calm the mind, teaches discernment and analysis, stimulate insight, and boots memory. It may facilitates knowing which information is important, and then retaining it.
Calcite may alleviates emotional stress and replaces it with serenity. It is said to be a stabilising stone and could enhance trust in oneself and strengthening the ability to overcome setbacks.
On a subtle level, a layout of the appropriate colour of Calcite cleanses, balances and energises all the chakras.
