Princess Alexandra wore the Chaumet Choker Tiara for her Religious Wedding to Nicolas Bagory at the Saint Trophyme Church in Bormes-les-Mimosas. I find it odd that she did not wear her mother’s Wedding Earrings, which were both of her sisters-in-law at their weddings. 

Grand Duchess Maria Teresa is wearing the Antique Emerald Earrings, Hereditary Grand Duchess Stéphanie is wearing the Grand Ducal Sapphire Earrings, and Princess Claire is in Queen Astrid’s Emerald Earrings.
