I did find this post very interesting :
Apparently, Princess Astrid wore Queen Maud's turquoise choker.
I would like to understand the collection of turquoise currently owned (or not) by Queen Maud and the Royal family of Norway.
This collection seems so huge ! Maybe the most important of all the royal families (with the Gloucester).
Thank you so much,
