Sunday, November 16 marked the 15-year anniversary of Prince William and Kate Middleton's 2010 engagement interview. While many royal fans rushed to copy Kate's blue Issa wrap dress, her sapphire-and-diamond engagement ring influenced trends just as much. The ring originally belonged to Princess Diana, and nearly 45 years later, the sparkling sapphire piece draws just as much interest—and holds considerably more value.
"Fifteen years later, it’s clear that William’s choice of his mother’s sapphire ring shaped not only their proposal, but a cultural shift in engagement jewelry," says Nilesh Rakholia, Founder of Abelini. The jewelry pro adds that Diana's engagement ring was considered "unusual" when Prince Charles proposed in 1981 since it wasn't a custom design like other royal brides received.
