What is Sugar Treatment? Matrix opal features opal within its host rock. To enhance its colours, the stone is soaked in a sugar solution then heated in acid, darkening the matrix and creating a vivid contrast that brings out the opal's natural brilliance. This process is used exclusively on Matrix opal.

Why Andamooka Treated Matrix Opal? At Iona Opal Australia, the only treated opal we sell is Andamooka Matrix Opal — genuine, ethically and sustainably sourced. Our Coober Pedy, Lightning Ridge, Mintabie and Queensland Boulder Opals are all treatment-free.
