Opal, derived from the sanskrit word upala, meaning precious stone, is associted with the 7th Zodiac sign Libra, the scales. Many believed for a very long time that the Opal was a stone of evil, bringing bad luch to all who posess it. It is said that this belief came from an 1829 novel depicting Opals as pure evil, this destroyed the European Opal market for 50 years untill a new Black Opal was found in Australia, reviving the Opal market once more.
