  • Opal is made with a combination of water and silica (SiO2.nH20)
  • The sparkle and glitter in Opals is known as ‘Play of Colour’ and is

caused by interference and diffraction of light passing through tiny silica spheres

  • Opal forms from the silica that is created from water seeping through sandstone. The silica then flows into cracks and voids in rocks
  • Forty meters below, a thickness of one centimetre of Opal has been estimated to take 5 million years to form and approx. 1 to 2 million years after, it has been said to solidify due to climate change
  • The myth that Opals are unlucky comes from the novel ‘Anne of Geierstein’
