Boulder opal from Queensland is found in the areas around Winton, Quilpie and Yowah. The opal is usually found in fractures and spaces in otherwise impermeable sandstone or ironstone

Boulder opal is considered to be one of the most versatile opals, it has all of the colours and patterns of expensive black or crystal oplas but it is contained within the ironstone which makes it extremely durable..

Boulder opal typically displays bright and vibrant colours. The natural iron stone base of boulder opal gives added stability and adds to the depth of colour produced in the gems. The varied and interesting natural shapes in which the gems occur make for added interest and unusual jewellery.

In order to tell if the opal is boulder or a doublet it is necessary to look at the side to see if the edge is undulating. In some cases, an ironstone or sandstone base is used for doublets and triplets, which may be hard to identify when they are set in jewellery.


Kings Opals is a family business, with a wealth of experience, expert skill, and opal knowledge that has been handed down from 1 generation to the next.
