[Source] Octagon black onyx

I have been trying to find an octagon black nyx. Buff top with a
double bevel. 17x15mm. They were once were commercially cut, but I
can’t find one now. Anyone got such a thing?

Bruce,

Have you tried The Stone House of Max Schuster. I’ve ordered various
shape onyx from them for years.
