10. To kick things off, we’re reaching back to an event we didn’t cover last week: the visit of the grand ducal family of Luxembourg to the Vatican. All three of the grand ducal daughters-in-law were in attendance. Hereditary Grand Duchess Stephanie wore a delicate pair of pendant earrings; Princess Claire donned an intriguing pair of stud earrings, and Princess Tessy selected a classic pair of pearl drop earrings.

9. Grand Duchess Maria Teresa (holding her granddaughter, Princess Amalia) wore a pair of drop earrings with round pearls for the papal visit. Note that she’s wearing white, while her daughters-in-law are wearing black; as the wife of a Catholic monarch, Maria Teresa has the right to exercise the privilege du blanc.
