Boulder Opal from Central Queensland.
Seams of opal running across and through the faces of three pieces of ironstone.
One piece has been rubbed down and marked while the other two pieces have
been semi cut down so they only need a little work.
The pieces are wet to bring out their colours.
The Ruler is measured in millimetres.
Measurements are generally rounded down and approximate.
Colour: Please note the camera has been white-balanced to give truer colours NO Photo Shopped enhancement.
