I'll take a pic of the stone selected as the replacement. I don't have an ID for it so will have to find out what it is. One aspect of stone that I enjoy is the slow pace. Not conductive when we need to get them done yet it is a patience situation.
Stone can be very frustrating like having MOP chip-crack. All that work and there it goes.
This azurite-malachite piece is from 2000. Gee, I wonder where it is now?
