As we know Queen Alexandra died intestate.
In his biography of Queen Mary James Pope Hennessy referred to Queen Mary saying that some of the children had met to discuss and divide between them Queen Alexandra's jewels.
That gave many the impression that it was King George and Queen Mary who determined who got what.
Then when Hugh Roberts published
The Queen's Diamonds he noted that Queen Alexandra had left notations in the inventory of her jewels about who got which jewels.
But, as Queen Alexandra did not leave a legal will, there is no guarantee that her wishes were strictly adhered to. The King, as her legal next of kin, may have decided to implement her wishes entirely, or to make adjustments for any reason he saw fit.
We know where some of the jewels went, but not all. I have always wondered whether Queen Alexandra would have noted that the emeralds given to her by North and South Wales were to go to the then Duke of York. We know that Queen Elizabeth the Queen Mother commenced wearing the emerald earrings (as pendants on her pearls) shortly after Queen Alexandra's death, but not who formally received them.
At times I have the impression that George V may have kept all the major gifts from civic bodies and then given them to individuals. Clearly QEQM had the emerald earrings which were part of the gift of North Wales, but she was never seen wearing the Prince of Wales feather brooch and only commenced wearing the Welsh Leek brooch and the emerald bracelet given by South Wales after she became Queen.
