The Prussian Tiara
Made by the German court jeweler, Koch, for the only daughter of Kaiser Wilhelm II, Princess Viktoria Luise, the Prussian tiara features a band of laurel leaves on top of the tiara, resting on gem-set columns and a meander base. In 2004, Queen Sofia loaned the item to her daughter-in-law then-princess Letizia of Spain for her wedding to King Felipe VI.
