The Stone is a bed of quartz front and back and is natural, FAST, yet fine, the BBW is quartz too, I was shocked to see that, have any of you seen that in a coticule?

I looked and searched for garnets, when I dropped down to 45 power and you could see what appeared to be garnets, stained quartz I'm thinking.

I wonder if there has ever been a study of Coticules with the electron microscope??
