Josefine, first of all: Thanks again for posting great pics.
Regarding the emerald necklace you posted on 'Queen Silvia Jewelry II' (Post 54): The necklace plus matching earrings, bracelet & brooch (the last two rarely worn) are modern, and they were a gift to the Queen by the King in the mid-eighties.
But the last pic on your post # 54 (with Queen Silvia wearing a pink dress) shows a totally different set of emerald necklace and earrings. She has only worn it for about two or three years and the provenance is unknown. If you look closely, you'll see that the earrings (much longer & dangling) and the necklace (two cabochon center stones) are indeed different from the other set.
I think the new one was first worn on a state visit to Bulgaria (in 2002?).
So Queen Silvia does indeed have two complete different modern demi-parures of diamond & emeralds.
Plus the historic Bernadotte emerald necklace, of course.
The black pearl necklace with the diamond center and the necklace with very large multi-colourded pearls in grey, black and yellow seem to be new additions to her collection as well.
