Tiaras remain a powerful symbol of royalty, with the ruby tiaras from the Dutch royal collection highlighted as significant pieces in European history. The Ruby Peacock Parure, commissioned by Queen Wilhelmina, features a unique design and has been recently worn by Princess Catharina-Amalia at a royal wedding. Meanwhile, the Duchess of Wellington shone at the State Opening of Parliament in a stunning diamond floral tiara, part of her family's collection, reflecting a rich Victorian heritage. In a more contemporary setting, Kate Middleton captivated audiences at Wimbledon with her stylish appearance, showcasing sustainable fashion through her By Pariah Sabine Hoops earrings, which quickly sold out after her appearance. These earrings, named after the founder's mother, emphasize Kate's commitment to supporting eco-friendly brands. Overall, these royal fashion choices highlight the enduring appeal of both traditional and modern royal jewelry.
