The origin of the stone’s name is up for debate. While many assume that it’s derived from the Sanskrit ‘Upala’, others opine its origins in the name of the Roman Ops, the goddess of fertility. In antiquity, the rare stone was cherished because of its unique, rainbow-like appearance (second only to rubies) and has been included in the crown jewels of many European countries. In the 1800s, Sir Walter Scott’s novel Anne of Geierstein turned the stone’s reputation from one of good luck to something wholly negative after killing off one of his characters who possessed an opal talisman, causing sales to crash and remain stagnant for 50 years. Until the 19th century revealed another source in Australia (now making up nearly 97% of the world’s supply) the only known place the opal could be found was in Cerevenica in modern day Slovakia.
