Fascinating and fantastic video. There aren't enough long form, informative videos about gems and minerals by people who both know and care about them on TH-cam. Thanks, keep up the good work.
I'm not sure why GIA just doesn't ask cutters for their opinion. No offense to this obviously smart guy but he has no idea how to cut a diamond and thus leaves the viewers that some mystical parts are still not fully understood. Cutting and polishing diamond is not rocket science. But as you can see.... You need to know how to do it.
