Queensland Boulder Opals

We stock a large collection of top quality Queensland boulder opals from the fields of Koroit and Yowah. 

Boulder opals are found and mined primarily in Queensland and are usually formed as a matrix in a host rock (normally ironstone) and the patterns and play of colour can range from numerous tiny flecks in the ironstone to a full face of opal with colour and brightness to rival those of other any of the other fields in Australia.  Many people also do not realise that Queensland produces black boulder opals which can be particularly eye-catching and are highly sought after as a result.

Values vary widely between those which are very affordable while still being highly attractive for use in jewellery, to those of highest gem quality which can command values of hundreds or even thousands of dollars per carat.
