Prince Rainier III of Monaco originally proposed to Grace Kelly with a Cartier eternity band of rubies and diamonds. When he saw other leading ladies in Hollywood were flashing bigger rings, he quickly ordered this 10.5-carat emerald-cut diamond flanked by two baguettes, also from Cartier.
Queen Elizabeth II
The diamonds for Queen Elizabeth II’s engagement ring from Prince Philip have a special history: They came from a tiara belonging to Philip’s mother, Princess Andrew of Greece.
Lucky Princess Diana, she got to choose her own ring from a selection presented by Garrard Jewelers when Prince Charles proposed. There are a few different theories on why Diana selected the 18-carat oval sapphire surrounded by 14 diamonds: the color matched her eyes, the Queen may have actually selected it, or as Diana was later quoted as saying, “It was the biggest.”
Sophie, Countess of Wessex
Following in family tradition, Prince Edward also proposed with a ring from the British royal jeweler Garrard. He presented his bride Sophie Rhys-Jones with a two carat oval diamond, flanked by two smaller heart-shaped gems—the ring is worth an estimated $150,000!
When perennial bachelor Albert II, Sovereign Prince of Monaco, proposed to Charlene Wittstock he did it in style. He presented the former South African Olympic swimmer with a serious sparkler that features a pear-shaped center diamond set in gray gold and embellished with round diamond brilliants, created by Maison Repossi. It’s estimated to be worth upwards of $100,000!
