Boulder Opal
Crystal Properties:
Colour: Exhibits a diverse array of colours embedded in a dark brown ironstone base. The opal forms thin veins and patches within the host rock, displaying vibrant flashes of green, blue, red, and sometimes gold, which is known as the 'play of colour.'
Chemical Composition: Hydrated silicon dioxide with an ironstone matrix.
Hardness: Ranges from 5.5 to 6.5 on the Mohs scale, though the ironstone matrix is usually harder.
Transparency: The opal itself can be opaque to translucent, while the ironstone is opaque.
Lustre: The opal portions have a vitreous lustre, contrasting with the matte finish of the ironstone.
Historical and Geological Background:
Boulder Opal is unique to Queensland, Australia, and is prized for its brilliant play of color contrasted against a dark, iron-rich base. Unlike other opals, boulder opals are not fully opalized; instead, they form in fissures and crevices within the boulder ironstone. These formations result in highly individual patterns and a strong, durable gemstone. Historically, Aboriginal Australians have revered opal, seeing it as a stone embodying the essence of their land.
