Not all that glitters gold is about pyrite. The Greeks considered the mineral a symbol of courage in battle, ardent passion and reckless courage. The stone was especially prized in pre-Columbian America, and scholars tend to consider it the lost "gold of the Incas". In the Middle Ages, alchemists loved working with pyrite. As a talisman, the stone is popular with those who work with fire and fight with it, as well as people who guard the law. Lithotherapists believe that the mineral is able to improve mood, raise overall tone, and increase performance. Created using pyrite, chunk symbolizes optimism, joy of life, and determination.
