In the middle ages, the opal was known as the “eye stone,” because it was believed to have a magical power which would help its wearer have sharper eyesight. Blonde women were known to collect as many pieces of opal jewelry as they could muster, because the opal was believed to contain within it the power to magically keep blonde hair from losing its luster and bright golden color.
Some cultures thought that the elaborate and illuminating colors of the opal, when reflected directly into a persons eyes, would render them invisible to that person. Thus, it was believed that an opal charm, when used properly, could give its owner mystical disappearing powers.
