Thanks OmerH. It is interesting to know what happened to the amethyst parure as many have speculated over its sale, some believing that Queen Elizabeth the Queen Mother sold it at auction. Our fellow poster, Franck, never believed that and tried several times to verify if QEQM sold the set. What we don't know is where the parure is today.

There is also still the unresolved question of when Queen Mary acquired the set. It certainly wasn't in 1908. The photos I found pre-date 1908 and, if I remember correctly, Kongetro found a reference to Queen Mary wearing them in Norway circa 1900-1901.

For those who are interested there was an interesting discussion on RJWMB in May 2017
