Andamooka Opal

Andamooka, in remote South Australia, produces a distinctive and fascinating variety of matrix opal — natural opal interwoven throughout its host limestone rock. Unlike other opal types, Andamooka matrix opal is typically treated through a sugar-and-acid process that darkens the host rock, allowing the opal colour to pop dramatically against a near-black background. The result is a striking, earthy gemstone with vivid play-of-colour that no other field produces. All pieces are hand-cut and personally selected by Iona, a Certified Opal Specialist.
