Princess Diana's jewellery collection in pictures: From tiaras to that engagement ring

This month marks 20 years since the loss of one of the world’s most beloved muses, Princess Diana.

Crowned by the nation as the ‘People’s Princess’, Diana enchanted the globe with her down-to-earth nature and innate ability to connect with others.

But one of her most memorable traits was her sartorial strength. From ’80s tartan power suits to sweet pie-crust collars, Diana was certainly not afraid to break Buckingham Palace’s fashion protocol.

The Princess of Wales would even shun royal accessories when greeting children. After all, she famously argued: “You can’t hug a child in a hat.”

And she approached her jewellery collection with the same free spirit as her inimitable wardrobe. From her sapphire engagement ring to the Spencer tiara she famously donned at her nuptials , Princess Diana’s jewellery box is something to behold.

Every single piece from her collection bears memories from key milestones in her life. Whether it is the necklace engraved with the name ‘William’ following the birth of her first son or the ‘Swan Lake’ pearl necklace she donned on one of the final public engagements before her death.

And despite the fact many of her treasures have since been sold at auction, many will argue that her royal gems are priceless.

Most famously, Prince William proposed to Kate Middleton in October 2010 with his late mother’s sapphire engagement ring.

In memory of the late Princess of Wales, take a look back at her most unforgettable gems.
