Wax to patch stone pendant

I have an opaque stone pendant with an approximately half-inch chip
on the back/side; if the stone is viewed from the front, the chip is
not visible; however, viewed from the side it bothers me. I was
thinking perhaps I could fill it with hard wax - can anyone tell me
what type of wax is used for this purpose?

Thanks,
Jean Petree

Try a 2 part mixed epoxy clear. That may help, or cream colored.

that’s what i’d use, as well…maybe tinting it to match the stone
colour.
