Cutting the next batch for the website.
Chasing opal seam in sandstone from Mintabie mined in the 1980’s. These have been in the “Too time consuming box “ for years.
This lot is preformed, shaped and ready for final cutting and polishing.
Very time consuming to get to this stage but so rewarding. Lots of nice surprises hiding in the rough.
