Most of the tiaras are known for their association with royalty or nobility, but this one’s a little different: it’s known because of its association with Hollywood royalty. It was given to Elizabeth Taylor by her third husband, Mike Todd, in 1957. The tiara dates from around 1880 and is made of old mine-cut diamonds mounted in platinum and gold in a design that includes central scroll motifs topped by single diamonds and separated by latticework.
