The Prince Albert
The sapphire surrounded by 12 diamonds was a gift from Prince Albert to Queen Victoria the day before their wedding on 9th February 1840. Victoria wore it on her big day, and constantly throughout her marriage while Prince Albert was alive. Her daughter-in-law Queen Alexandra wore it at her coronation, and it was passed to the Queen in the year of her accession. She has worn it many times since, including for Ascot, her Christmas broadcast in 1987 and a trip to Saudi Arabia.
