I am glad you enjoyed it GillW. It is not something everyone would appreciate, but I enjoyed reading about the technical aspects of this diamond and some verifiable facts rather than just the mythology. The authors have certainly added to our understanding and given us a great deal to think about.
I will try to follow up (if I can) the reference to the 96 smaller diamonds being sold. Obviously, in contrast to what Field said, they were not presented to Queen Mary.
