Just one to post tonight, but I can't wait. This is a new prototype I made for Suzanne at modify. 30 mm argentine lignum vitae with the ammonite prong set. The prongs are 20 gauge gold filled wire. The light shines nice through the shell and gaps around it.
I can definitely do these in larger sizes. I won't be able to do any below about 28 mm. Maybe a tear set? Any one interested, let me know.
