I just wish that I had an example to show you.
I have two that “may be” and are not so convincing.
The Electric yellow CAC slag’s are the tops as far as slag’s go in my opinion. They just light up as no other, in hand, under flash, in sunlight---the tops as far as any yellow ever was or will be.
I hope that someone will share one or two in an image---I just love these types.
Marble—On!
