Product Description

This is a dark but bright natural wood replacement boulder opal from our mine in western Queensland showing multicolours.  It has a slight undulating surface where 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.

Stone size: 16.8mm long x 5.9mm wide x 2.8mm thick and weighs 2.25cts
