It was thought that sunstone had magical properties and could call forth the power of the sun. In ancient Greece, it was thought to be a depiction of the sun god, who bestowed life and wealth onto those who were fortunate enough to own one. The first inhabitants of Oregon used it for trade and barter. Due to the presence of copper crystals in it, Oregon sunstone is particularly unique. These sunstones, according to Native American belief, were marked with the blood of a mighty warrior who had been arrowed. The blood gave the stones a holy crimson color and sacrificial power, imbuing them with the warrior's spirit.
