Named after the aquatic lotus blossom, the word comes from the Sinhalese language, that of an ethnic group native to the island of Sri Lanka. Unsurprisingly, the padparadscha sapphire is most commonly found and mined in Sri Lanka. Madagascar andTanzania are home to some deposits of the gemstone, but the Sri Lankan padparadscha sapphires are undoubtedly the finest. The beautiful gemstone received a lot of media attention recently when Princess Eugenie announced her engagement to Jack Brooksbank in January of 2018. Her engagement ring featured an oval-shaped coral-coloured padparadscha sapphire within a diamond cluster surround. It has been compared to the style of her mother, Sarah Ferguson’s engagement ring which featured a Burmese ruby in a similar setting. Princess Eugenie and Jack Brooksbank were married atWindor Castle in October, 2018.
