Key Aspects of Boulder Opal
Where it is found: Found exclusively in Western Queensland, Australia, in areas like Quilpie, Winton, and Yowah.
  • Appearance & Colors: They display vivid flashes of blue, green, red, gold, and purple. They often appear as thin, brilliant veins of color within brown ironstone, creating a "picture stone" effect.
  • Cost: While rare and valuable, they are generally less expensive than black opal. Pricing is often "per piece" rather than per carat, heavily influenced by the intensity of color and brightness.
  • Usage in Jewelry: Because they are natural, solid, and durable (due to the ironstone backing), they are highly sought after by designers for unique, often asymmetrical or freeform jewelry.
  • Care: As they are solid (not doublets), they are durable but should be treated as precious jewelry. Clean with warm water and mild detergent; avoid ultrasonic cleaners or harsh chemicals.
