Tigereye's glorious shimmer and silky texture will light the fire within and get you motivated. Known by many as the ultimate power stone, Tigereye helps balance toxic emotions and keep the mind focused on your true desires. For centuries it has also been linked to the magical tiger, the king of beasts in Eastern mythology. Roman soldiers carried it to be brave in battle and it has been highly regarded throughout history as a stone of prosperity and good fortune. Tigereye is a member of the quartz group of chalcedonies. It is one of the chatoyant gemstones. Chatoyancy exhibits a changeable silky luster as light is reflected within the thin parallel fibrous bands. This effect is due to the fibrous structure of the material.
