About Boulder Opal

Boulder opal is found only in Western Queensland, Australia, where seams of precious opal form within ironstone boulders. Unlike other opal varieties, boulder opal is cut with its natural ironstone host rock left on the back of the stone. This dark backing intensifies the colour play. Orange-bodied boulder opals are prized for their warmth — they sit beautifully against both yellow and white gold.
