An Australian boulder opal is a type of opal that is found embedded within ironstone boulders. It is exclusive to Australia and is renowned for its vibrant colors and unique patterns. This opal variety typically forms as thin veins or patches within the host rock. Unlike other opals which are mainly composed of silica, boulder opals have a combination of precious opal and ironstone, giving them a distinctive appearance. The opal's play-of-color is the most fascinating aspect of these gemstones.
