Wonderfull story btw!! ❤️
I hope it was a fun joke between the two cousins, and not done from spite?
I am reminded of a a amusing story told I think by Queen Anne of Romania, about her mother Princess
Margaretha w hile working in a hat shop, in USA.
The Crown Princess Martha of Norway came into the shop, wearing a hat, which she removed while trying various shop hats. Another customer, tried on the Crown Princess es hat and Princess Margaretha promply sold the hat, fully knowing it was the Crown Princesses hat.
Also, to me it looks like there is a darker central motif / gem compared to only white diamonds.
Indeed, as seen in this slightly better picture:
