It seems Princess Madeleine ofered a fairy tale party to children from a fundation, granting them a wish. She dressed fully like "a princess", wonderful aquamarine tiara from Pss Sybilla included, to the litlle girls delight. She wore chandelier aquamarine earrings that I do not remember seing, any information on them? I remember seing her wear long aquamarine earrings but not these ones. I apologize if they have already been discussed here.
