pearls are a girls best friend. the neklace belonged to Amalia van Solms (married to Frederik Henrik, youngest son of Willem the Silent) and in her will she decided that this necklace should remain within the family forever...
I think the pictures of the Queen at Enschende and Volendam show what a truly human and caring person she is. One could never imagine Queen Elizabeth putting her arm around a greiving person or even showing human emotion of any kind.
