A large triangular free form solid Queensland Boulder opal.
The opal contains large open crystal opal section of good depth and transparency can be seen throughout. Transparent yellow potch adds character high on one edge. Small translucent inclusions can be noticed deep down under the opal surface. No crack are seen as we examine under the high magnification.
Amazing stone of 87.80 carats. Solid seam and well attached to the Boulder. Could be made in a beautiful piece of jewellery. This specimens a real talking piece.
