Queen Elizabeth II wasn’t the only British royal lady at Tuesday’s garden party. Here are three more princesses who showed up in their bejeweled best!

The Countess of Wessex wore a pair of earrings that we saw quite a lot last summer: cluster earrings by Dior. The earrings are made of resin beads designed to resemble pearls.

Also wearing cluster earrings: Princess Alexandra, who paired hers with one of her favorite pearl choker necklaces.

I’m especially intrigued by the Duchess of Gloucester’s garden party jewels. This appears to be a set of coordinating earrings, brooch, and necklace. (Also — check out that elaborate umbrella handle!)

Here’s a closer look at the necklace and the brooch, which features intriguing heraldic motifs.

Queen Elizabeth II hosted a garden party at Buckingham Palace on Tuesday afternoon, and she wore one of the earliest major additions to her jewelry box: the Flame Lily Brooch.

The diamond and platinum brooch was a 21st birthday gift; it was a present for the then-Princess Elizabeth from schoolchildren in Rhodesia (now Zimbabwe). It was also the first brooch she wore in public after her unexpected accession to the throne in 1952.
