The Boulder Opals

Queensland, Australia

Discovered in the 1860s, the Boulder Opal  is a stone found exclusively in Australia, in the state of Queensland.

These are veins of Opals (silica) formed in the cracks and cavities of a ferruginous matrix (sedimentary rock rich in iron). The English word "Boulder" translates to "rock".

Boulder Opal is a stone associated with spirituality. It is used in lithotherapy to purify and stabilize energies. Opal is the stone of the month of October and the 21st wedding anniversary.

It symbolizes light, hope, appeasement and harmony.
