These earrings are made of natural amethyst, not glass or imitation material. Amethyst often comes in shades of violet and purple. The meaning of Amethyst is spiritual healing, calmness, and wisdom. Amethyst has the ability to convert lower vibrations to higher frequencies, which then transforms negative energy to love energy. It works with the Third Eye Chakra, which is located between the eyebrows. This provides peaceful energy, which is perfect for meditation and for developing psychic abilities.
