Originally, Prince Rainier III proposed to Hollywood icon Grace Kelly with a simple eternity band dotted with rubies and emeralds. He later got her a platinum Cartier engagement ring with a 10.47 carat emerald-cut diamond flanked by two baguettes. Kelly wore the engagement ring in her last movie before becoming princess of Monaco, “High Society,” which also featured Bing Crosby and Frank Sinatra.

That diamond ring was displayed at the “Grace, Princess of Monaco: A Tribute to the Life and Legacy of Grace Kelly” exhibit at Sotheby’s in New York in 2007.

Queen Elizabeth II

The diamonds in the Queen’s 3-carat diamond engagement ring came from a diamond and aquamarine tiara that belonged to Prince Phillip’s mother, Princess Alice of Battenberg (later known as Princess Andrew of Greece and Denmark), who was Queen Victoria’s great-granddaughter. The ring is made up of one three-carat diamond surrounded by 10 smaller diamonds.

The Prince additionally selected sones from the tiara and turned them into a wide diamond bracelet for the Queen, which he gave to her as a wedding gift.

Princess Diana

Princess Diana picked out her own sapphire engagement ring from a Garrard catalogue. Her ring had a 12-carat oval Ceylon sapphire that was adorned with 14 solitaire diamonds, resting on a white gold band. It cost about $36,000 in 1981 but today is priceless.

Upon the Princess’ death, her sapphire engagement ring was passed on to her son Prince William, while her famous wedding dress was given to Prince Harry. The sapphire and diamond engagement ring was then given to Kate, Duchess of Cambridge, when she got engaged to Prince William in 2010.
