[Source] Flat onyx

Where would I find a couple pieces of onyx about 16mm x 16mm x 2-3mm
thick. I broke an onyx ring and I need to replace the flat onyx. I
need to cut it to fit so a bigger piece could also be used. Thank
you everybody in advance.

try: Joseph Stachura in Oxbridge, MA, USA

then do a search for “onyx” this got me five+ pages of listings for a
bunch of different shapes/sizes. and if you don’t see it, call them,
they might still be able to assist.

Would black jade work?

Steve- Are you sure you want onyx? I’d recommend black jade. Black
jade is much more durable than onyx.

Have fun and make lots of jewelry.
