Koroit opals belong to the Boulder opal family and are extremely rare. They formed through deposits of water containing silica that became trapped inside iron minerals termed Matrix.
Koroit opals are highly sought after for their intricate patterns where the colors of the earth and of the crystals merge into wonderful structures that have inspired Aboriginal art since prehistoric times, and for this reason they are called "tribal patterns".
Australian Boulder opals are a precious stone that gains value over time and will add prestige to your collection.
