I wish I knew what this stuff was. The dark part is pretty hard, with softer yellowish dendrites.

35mm x 19mm x 4.5mm.   Weight: 23.45 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.
