Australian Boulder Opal Boulder opal is found in Queensland, Australia where precious opal forms in veins and patches within brown ironstone boulders. When the opal is mixed through the ironstone it is called matrix opal.
Boulder opal is very durable due to the ironstone backing the opal forms on.
Because water content within the opal is very low it almost never cracks or crazes as it ages. Aids inner beauty, faithfulness, and eyesight and helps recall past lives.
