This is the largest cabochon I've ever cut. I found this unusual chunk of Porcelain Jasper while teaching a class at William Holland and thought I'd show off to my students with it. I call it my "self-portrait." Of course, it's going into the collection!

69mm x 55mm x 7mm.   Weight: 230.65 carats.
