Opal Facts & Folklore

  • Australian aboriginal tribes believed that opals were the Creator’s footprints on Earth.
  • Necklaces with opals set in them were worn to repel evil and to protect eyesight. 
  • Opals help to control temper and calm nerves. A dream of an opal means that good luck will come.
  • Each opal is made of tiny spheres of amorphous hydrated silica; its water content makes it prone to cracking or crazing (many fine cracks). This can happen if the gem dries out, such as might occur when exposed to high temperatures or long periods of low humidity. The gem is relatively soft, with a hardness rating of only 5.5. (Never place an opal in an ultrasonic jewelry cleaner: The vibrations can crack the gem.)
