The Stuart Tiara:
This Tiara, with around 900 diamonds and 39.75 carats of them belonging to the massive Stuart Diamond alone. The tiara can be worn as a smaller piece by removing the top bits containing the Stuart Diamond. Its history dates back to Queen Mary II and King William III (Willem III), who was the Prince of Orange when they purchased the enormous Stuart Diamond in 1690 and had it set in a brooch. A long history of back-and-forth between England and the Netherlands ensued and the diamond was turned into a pendant for a necklace, but in 1897, the Stuart Tiara was born when Queen Emma of the Netherlands commissioned the piece for the investiture of her daughter, Queen Wilhelmina. Made in 1897 by Schürmann using diamonds provided by Queen Emma, including the Stuart Diamond. Worn for the first time by Queen Wilhelmina at her investiture in 1898. Now part of the family's jewel foundation. Worn by Queen Wilhelmina, Queen Juliana, and Queen Maxima. Worn as a wedding tiara by Queen Wilhelmina (1901).
