Calcite comes in many different colors and is a strong energy amplifier. It is a teacher stone; meant to guide humanity towards their 'soul purpose.' It facilitates this by stimulating past 'memory' or 'remembrance' of why you chose to travel here to this time now. It is a wonderful astral projection companion (but I would suggest using it alongside a strong grounding stone to help anchor you).
It is a powerful tool, meditation piece, Chakra resonator, and magic helper. Calcite is directly linked to the Zodiac signs of Cancer, Leo, and Aquarius. This crystal helps to stimulate a joyous, light-based, and soul-brightening energy.
