ICYMI, Prince Charles celebrated his 70th birthday last night, with a super fancy party at Buckingham Palace, and royal guests from around the world attended - Queen Rania of Jordan, Prince Albert and Princess Charlene of Monaco to name just a few.

Naturally, his family were also there, and pulled out all the stops for the black tie dinner - and that involves diamonds of course.

While we didn't catch a glimpse of the Duchesses of Sussex and Cambridge's outfits, we did see their statement earrings and they were beautiful.

Kate Middleton matched hers to her pink ballgown (we could just about make out the sleeves), opting for a pink diamond drop style, which she has worn a few times before, at the 2017 BAFTAs and at the 100 Women in Hedge Fund dinner in 2011.

There isn't much info out there on the earrings, but there is speculation that they were a wedding gift as she got married earlier that year.

Meanwhile, Meghan also opted for some coloured diamonds: her earrings featured three strand dangling from a larger yellow diamond. Stunning. They are believed to be on loan from the Queen.
