Boulder Opal

GST Included.

Sectioned Boulder Opal sourced from the Koroit Opal Fields, Queensland.

Exhibiting rich veins of Opal flowing through dark ironstone, this unique Australian gemstone is set in a glass display case with bamboo base to make the perfect Australian gift.

Known to the indigenous people as 'fire of the desert', the opal is Australia's national gemstone.

Thought to have formed up to 100 million years ago, Boulder opal occurs as water seeps through sandstone, dissolving silica, and depositing into cracks and voids in ironstone rock formations. This process occurs over millions of years to form layers of opal as the water slowly evaporates.
