Rhodonite, from the Greek rhodon, meaning "rose," is a manganese iron magnesium calcium silicate with a hardness of 5.5 to 6.5. It is recognizable by its beautiful pink color, often patterned with black veins. In the Ural Mountains of Russia, locals named it "Orletz"—"the eagle stone." Rhodonite is useful in helping to raise one's self-worth and self-confidence. It can stimulate the heart chakra and be used to activate love energies. It can also dispel anxiety and soothe nightmares, and is said to balance yin and yang. Rhodonite is mined in Australia, Brazil, Russia, Sweden, and the United States, where it is the Massachusetts state gemstone.
