Here are two cobalt spinels that I’m currently looking at. One is 1.43 ct (first 2 in video) and other is 1.41 ct (second 2 in video - tweezers, and left on the paper with two). The former is Guild certified and latter is GFCO. Based on the videos that you see here do you have any thoughts on both? I know videos aren’t perfect, but in terms of quality and what you would trust more than another.
