What Is Boulder Opal?
Boulder Opal is a type of precious opal that forms within cracks and cavities of ironstone boulders or sandstone, creating a stunning natural contrast between the opal’s vibrant colors and its earthy host material. The ironstone backing gives the gemstone remarkable strength and durability, making it ideal for crafting jewelry like pendants, earrings, and rings.

The story of Boulder Opal begins in the state of Queensland, Australia, where the world’s finest specimens are unearthed. Major opal-mining areas such as Winton, Koroit, and Yowah are renowned for producing some of the most vibrant and high-quality opals ever discovered.
Boulder Opals are mined from large ironstone boulders in the rugged Australian outback, a process that involves locating seams of opal embedded in the rock. These seams were formed millions of years ago through the deposition of silica-rich water, which hardened over time to create dazzling opal formations.
