Hello, Guy. All I found in my search was “Jewelry Manufacturing in
the Developing Gold Markets of the World” by Mark Grimwade from the
Proceedings of the Santa Fe Symposium on Jewelry Manufacturing
Technology, 1996. Maybe someone on Orchid has the email contact to
’World Gold Council’ or ‘Worshipful Company of Goldsmiths’, both of
whom he consults. You might find “Introduction to Precious Metals”
(London, Newnes, Technical books, Butter Worth, 1985) through them.
