Thanks, Mark.
Every year I spend one day at a local high school taking over a friend's metalworking and sculpture classes, teaching about opal, lapidary and jewelry making, including demos of my lapidary equipment with hands-on by some of the students. It's a lot of fun and some get excited about lapidary.
I always donate some of what I call my "student grade" opals that I've saved during the year. Most of these didn't quite measure up, too little fire or very weak fire, but there's usually a couple of nice opals that have structural issues or maybe objectionable defects.
I'm with you on the various stages of completion. I have numerous doublets that seem to always be waiting to be cut, some stones for which I haven't figured out the best cutting strategy, and lots of "not sure it's good enough to cut but it's certainly too good to toss" pieces.
BTW, I'm wondering why you didn't slice that new listing with the garnet crystals down the middle to make two stones from front and back?
