I think this is Pyrite in matrix, also known as "Fool's Gold." This one is the perfect size for a man's ring. There's one large Pyrite fleck in the center and another on the lower left corner. Pretty!

16.5mm x 14.5mm x 6mm.   Weight: 14.25 carats.

Every one of my cabochons is custom cut to take the best advantage of the particular slab from which it is fashioned. Colors may vary somewhat from what is pictured due to differences in computer monitors.
