Boulderopal refers to precious opals embedded in veins and cracks of the surrounding mother rock. This valuable gemstone from the Outback includes the mother rock, the matrix. The noble opal cannot be separated from its mother rock. The proportion of precious opal visible on the surface of the Boulderopal determines the gemstone's value.
Boulder opal occurs exclusively in Queensland (Australia). In a distribution area measuring 300 km by 1000 km, deposits of mineable Boulder opal are mined at various locations. This opal belt corresponds to the Cretaceous Winton Formation. From the late Cretaceous period, weathered deposits from rivers and lakes formed an iron-rich zone, where silica-rich precipitates from the overlying layers accumulated in cracks and fissures near groundwater. There, they consolidated through drying into gel and eventually into secondary formed opal.
