Query: Fairly thourough look at an extensive collection

A well written guide to QE II's elaborate collection of precious stones. Comes complete with her family tree as a reference, which you may find handy to refer to as the author traces back how most of the pieces came to the Queen through her ancestors. Many pictures, however, there are almost as many of Queen Mary as there are of Queen Elizabeth II! I especially liked the way it was discussed how some older pieces have been taken apart, reset, and reconfigured to make them do duty in the 20th and 21st centuries. A very well researched book that any royal watcher will enjoy. I would love to see the author devote a publication to the jewelry (real and paste) of the late Princess of Wales.
