Australian Iron Bolder Opal

Australian Iron Boulder Opal is a stunning and unique gemstone distinguished by vibrant, iridescent flashes of color set against a natural ironstone matrix. Found primarily in Queensland, Australia, this opal forms within iron-rich sedimentary rocks, where silica-rich solutions seep into cracks and cavities, creating brilliant, multicolored opal veins embedded in the dark host rock.

With a Mohs hardness of 5.5 to 6.5, Iron Boulder Opal is relatively durable due to the protective ironstone backing, making it suitable for a variety of jewelry designs. Its rich play-of-color ranges across the spectrum, often showcasing fiery reds, electric blues, and vivid greens that shift with the light.

Celebrated for its grounding energy combined with vibrant beauty, Australian Iron Boulder Opal is a captivating choice for collectors and jewelry lovers alike.
