Is there any piece quite as iconic as Lady Diana’s wedding day tiara? In 1981, she wore a stunning tiara that boasted 800 diamonds. But get this; it wasn’t just any tiara. It had a rich history, dating back through generations of the Spencer Family.

The story begins in 1919 when Lady Cynthia Hamilton got the central part of the Spencer Tiara as a wedding present. Then, to amp up the bling factor, she combined it with another tiara from the 1870s. Voila! The Spencer Tiara was born, shining with diamonds and a layer of 24-carat gold.
