The tiara and necklace in question appear to be crafted with turquoise and diamonds, forming a distinctive set that stands out among early 20th-century European royal jewels. After reviewing photographs of Prince Philip’s sisters, it becomes clear that the tiara was inherited by his eldest sister’s daughter, Princess Margarita of Hohenlohe-Langenburg.
Princess Margarita, who married Prince Gottfried of Hohenlohe-Langenburg in 1931, later wore the piece during the pre-wedding celebrations of King Juan Carlos and Queen Sofía of Spain in 1962. In one well-known photograph from that evening, she appears alongside her cousin, Princess Marina, Duchess of Kent, with the turquoise tiara prominently displayed.
Little is publicly documented about the tiara’s origins or current whereabouts, and it is unclear whether it remains within Princess Margarita’s family today. If anyone has further information—historical records, additional photographs, or confirmation of its current ownership—it would provide meaningful insight into the journey of this beautiful royal jewel.
