I'm still researching this one; all I can say for sure is that its origin is Kuwait, where a friend of mine tripped on it in the desert. Probably volcanic. Very dense rock.

39mm x 29.5mm x 7.5mm.   Weight: 74.70 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.
