56ct Solid Queensland Boulder Opal

Queensland Boulder Opal – Natural Loose Gemstone

This 56ct Queensland boulder opal carries the depth and drama of the earth itself. Swirls of ironstone frame electric flashes of opal colour—glimmering with hints of violet, gold, and indigo beneath the surface. Its polished freeform cut reveals the natural contrast between stone and colour, making it ideal as a bold collector's piece or the heart of a statement design.
