FUCHSITE is a dark green variety of muscovite containing nearly 4% chromium, which gives it its wonderful emerald green color. Muscovite, often found in compact masses with small crystals, is a potassium aluminum silicate hydroxide fluoride, with a hardness of 2 to 3. It was named for Johann von Fuchs, a German chemist and mineralogist. Fuchsite is said to have a strong connection to the herbal world and can increase the healing effects of certain herbal tinctures. It can enhance the transfer of energy from other minerals, and can be useful in speeding the healing process and improving the immune system.
