Opal

Australia's National Treasure, the Fire of the Desert has deep spiritual value for Aboriginal people.

The play of light or “schiller” displayed in opals is from light diffracting from compact tiny silica spheres into the seven colours of the rainbow. Boulder opal appears as coatings on sandstone, crystal opal in seams. Ninety-five percent of world’s opals are from the remote Outback.
