Personally, I love what CrystalsandJewelry.com has to say about the lore associated with calcite:
- Calcite increases and amplifies energy. This makes it an excellent stone for distance healing, as well as other types of healing. One of the energies it amplifies is learning abilities, and thus is a great stone for students.
- Calcite is a protecting, grounding and centering stone, and can help bring inner peace. Since calcite also promotes creativity and imagination, this inner peace it can bring is a vibrant one.
- Calcite has been said to increase prosperity. It can also be helpful in astral travel and in channeling, as well as increasing intuition. Calcite is also a stone of spirituality and wisdom.
- All calcites are helpful in lessening of fear and reducing stress. Calcite is probably the premier cleanser of stored negative energies in the human system, and works on all levels from the physical to the etheric. This makes it a very purifying stone. It can also be used to clear negativity in the environment, such as a room that it's in.
