BIG Rainbow Cal Silica cabochon! Nice colors and patterns. Man-made? This material is so pretty, I don't think anyone cares. Just a big, beautiful cabochon!

40mm x 25mm x 4.5mm.   Weight: 42.05 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.
