Queen Emma's Diamond Tiara features a trio of harp designs with large diamond rosette-style clusters in their centres. It was made for Queen Emma of the Netherlands in 1890. She often topped the piece with diamond star ornaments. Today, the tiara is part of the Dutch royal jewelry foundation, and it's worn often by members of the family, including Princess Beatrix, Queen Maxima, and Princess Laurentien. | Court Jeweller
