Deep in the coal mines, a lucky miner found an abundance of glittery coal, and its sparkle blinded his eyes. While sphalerite can be found in many colors, these mysterious-looking black types are made even more beautiful with their druzy. Sphalerite fills the body with golden light and imbues a feeling of 'lightness' within. It is warming, stimulating, uplifting, and strengthens the immune system. It encourages psychic and spiritual development and can be very helpful in meditation and visualization work.
