Thank you Maridje. Some of these brooches intrigue me, especially the last one. How I wish we could see the entire brooch.

Re the brooch worn in Canberra (as Duchess of York) I recollect that Franck identified it as the turquoise brooch (from the wedding gift parure) and that we found photos of Princess Margaret wearing it where it looked the same. I then found a couple of reports in Australian newspapers which said it was a turquoise brooch and not an opal brooch as many newspapers reported.
