Full Faced Color from Central Queensland Mines

The Winton opal field, situated in the heart of outback Queensland, is celebrated as the premier discovery location for high quality boulder opals. Because Winton material forms in large, stable ironstone boulders, lapidaries can cut stones that feature full faced color across their entire surface, with minimal host rock showing through. These stones frequently display broad sweeping patterns, including rolling flash, ribbon, and block patterns of royal blue, deep green, and exceptionally rare flashes of red.

For custom jewelry designers, Winton boulder opals are the absolute material of choice for creating statement pendants, as their natural brown ironstone backing provides robust structural strength. To ensure absolute trust, our collection is curated through direct relationships with Winton miners, ensuring that every stone is 100 percent natural, untreated, and solid.
