Excellent break down. I really liked how you demonstrated what happens when you break them. I just had a lab doing this stuff and didn't feel like I fully understood what I was doing, so this really cleared it all up.
I have some stones that can't be scratched by corundum even by diamond. I have no idea what stones they are. They do not seem like diamond at all. I have just uploaded the testing video.
