Boulder Opal is a unique and beautiful opal found in Queensland, Australia. It is easily identifiable because it is a mixture of ironstone and opal either in a matrix or layered. Every stone is unique and they are arguably the most affordable opal available. Another interesting type of Boulder Opal is the wood replacement fossil. These stones have replaced a cavity left over by old wood. This creates a stone with a unique wood pattern.
