On February 6, 1981, Prince Charles proposed to Diana with a 18-karat white gold ring topped with a 12-carat oval Ceylon sapphire surrounded by 14 solitaire diamonds. It was made by the crown jeweler Garrard and reportedly inspired by a brooch created in 1840 for Prince Albert as a wedding present for Queen Victoria. The ring reportedly cost Charles £28,000 at the time (about $35,000).
After Diana's death, her son Prince William proposed with the ring to Kate Middleton, Duchess of Cambridge
