Hi! You might check with Lapidary Journal (address, phone # in
each issue) as they have, for a number of years, featured
different facet cuts and I definitely know I’ve seen one for the
princess cuts and for bullets. Would look them up for you but,
unfortunately, I had to get rid of a 15-year library when I moved
to New Mexico last year. Good luck.
