About Australian Boulder Opal

Australian boulder opal is a type of precious gemstone that is found primarily in the mines of Queensland, Australia. It is characterised by its unique appearance, which is formed by the combination of opal and ironstone. The opal forms within veins and cavities in the ironstone, creating a striking pattern of colours and textures. Boulder opals can feature a wide range of colours, from blues and greens to reds, oranges, and yellows. The ironstone matrix can also vary in colour., ranging from tan to dark brown. Australian boulder opals are highly prized for their durability and unique beauty, as no two stones are exactly alike. They are often used in jewellery designs that emphasise their natural, organic feel, and are considered a valuable addition to any gemstone collection. Some of the most highly prized boulder opals feature intricate patterns and shapes, including "picture stones" that resemble landscapes, animals, and other natural scenes.
