This one’s a battle of diamond sparklers made by Koch!

This towering diamond tiara, which features tall diamond fringe pieces interspersed with much smaller diamond spikes, was made by Koch for the Sayn-Wittgenstein-Berleburg family in 1905. The tiara, which can also be worn as a necklace, entered the royal world when Prince Richard of Sayn-Wittgenstein-Berleburg married Princess Benedikte of Denmark. She’s still wearing the sparkler at royal events in Denmark today.

The jewelers at Koch made this neoclassical tiara for Princess Viktoria Luise, the only daughter of Kaiser Wilhelm II of Germany, in 1913. The miniature diamond and platinum kokoshnik features laurel wreaths, columns, and a meander base. Viktoria Luise’s daughter, Friederike, brought the tiara with her to Greece; her daughter, Sofia, brought it to Spain. It’s been used twice as a bridal diadem, most recently by Queen Letizia.
