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