This is a beautiful piece which I picked up recently which needed a little TLC before it was ready for me to list here in my etsy shop. The face of the stone is in very good condition. A nice polish with good red pin prick fire along one side. The red fire against the blue base color is a rare treat for Australian opals.

As can be seen in the pictures, the back of the stone has a few chips in it. The stone is already as thin as I'd want to make it, so rather than trying to grind these out and loose a lot of material, i decided to stop. The stone is stable and would be well suited to be set in a full bezel or wire wrap.

The white lines running diagonally across the stone are not cracks, simply different color pooch.

Weight: 17.34 carats
Size: 32.23mm x 23.8mm x 2.94mm thick.
Natural, Australian in origin.

I am more than happy to set this piece in a piece of jewelry for you if desired.
