Bright green natural Australian wood replacement opal from our mine in the Quilpie mining district of western Queensland. It has a slight undulating face because we have followed the opal vein using fine tools. It is quality cut and highly polished.
Wood replacement occurs in our mines where wood and plant material were deposited amongst the heavier sediments. When the ground became silicified some of this material was replaced with precious opal.
