After Charles' proposal (he did not immediately present Diana with a ring, so she could consider the implications of their marriage), Diana chose an 18-carat oval blue sapphire surrounded by 14 brilliant-cut diamonds and set in 18-carat white gold by Garrard Jewelers, the official crown jeweler for the British monarchy. This "store-bought" ring inspired many copies.
Prince Albert gave the former South African swimming champion a pear-shaped engagement ring of about 3 carats embellished with round diamond brilliants and set in a unique gray gold. Created by Parisian jeweler Maison Repossi, it's a royal choice.
Upon the Swedish Crown Princess' engagement to her longtime boyfriend (Daniel proposed on one knee in the grounds of Drottningholm Palace), the couple kept quiet about the ring. It was later revealed that it's a classic engagement ring with a brilliant cut diamond of two to three carats, most likely purchased from the jeweler WA Bolin in Stockholm.
While vacationing in Kenya in October 2010, Prince William proposed to his long-time girlfriend with his mother, Princess Diana's engagement ring. Lady Diana Spencer selected an 18-carat oval blue sapphire surrounded by 14 brilliant-cut diamonds and set in 18-carat white gold by Garrard Jewelers, the official crown jeweler for the British monarchy. The groom said he wanted his mother to be part of this special time in his life and therefore chose to give his bride her ring.
A ring of great historic value, Camilla's heirloom engagement ring was left to Charles by his grandmother, Queen Elizabeth (a gift from her mother-in-law upon the birth of Queen Elizabeth II). An art deco design, the platinum ring is comprised of an emerald-cut diamond flanked by three diamond baguettes on both sides.
For the Duchess of York, Prince Andrew helped design an oval Burma ruby ring (to compliment her red hair) from Garrard Jewelers, surrounded by a cluster of 10 drop diamonds. It is set in 18-carat yellow gold, and has a white gold band.
