Upon request, I’ve uploaded an explanation of the process that gives the flat base on a cabochon, which is needed dop the stone for cutting. This process is the same for Ethiopian Welo opals, Australian opals, or any other type of cabochon, especially those with directional asterism or color flash.

Please let me know in the comments what you want to see next!

If you’re interested in any opals, I have them for sale on Heaven-in-earth.com
