The History of Princess Diana's Aquamarine Ring

• Princess Diana's aquamarine ring has a fascinating history that dates back to the 1960s. The ring was originally a gift from Brazilian socialite Lucia Flecha de Lima to Queen Elizabeth II. The queen had the ring designed by the famous British jeweler Asprey, who created a stunning emerald-cut aquamarine stone set in yellow gold. The ring was added to the queen's vast collection of jewels and was worn on several occasions, including the state opening of parliament in 1974.

• Princess Diana first wore the aquamarine ring in 1997, just a few months before her untimely death. She paired the ring with a stunning blue cocktail dress and wore it to a Christie's auction preview in New York.

• The ring caught the eye of many, and it was later revealed that the ring was a gift from her friend, the businessman Richard Burton. The ring was auctioned off after Princess Diana's death, fetching a staggering £1.8 million.
