Everyone's talking about Kate Middleton's 'push present' from Prince William

And for all the right reasons...

Despite still being on her maternity leave, Kate Middleton has been in the public eye a lot over the past fortnight.

There was Prince Louis' Christening last week, and then two appearances at Wimbledon over the weekend, attending with sister-in-law Meghan Markle for the women's final on Saturday and husband Prince William for the men's final on Sunday.

But it wasn't her company or bold fashion choices (millennial yellow) that got the public talking. Instead, it was a new accessory the Duchess seemed to be sporting - a huge sparkling citrine ring.

The jewel is reported to be a 'push present' from Prince William, a royal tradition whereby the mother receives a gift from their spouse after giving birth.

The Duke of Cambridge has reportedly gifted Kate a 'push present' after the birth of each of their children, presenting the Duchess with an eternity band after Prince George's birth, and a pair of custom Kiki McDonough green amethyst and diamond earrings after the arrival of Princess Charlotte.

While close up flashes of the citrine rock stole attention from Novak Djokovic's victory, it's not actually the first time we've seen it, with the 36-year-old first wearing her gift at Prince Harry and Meghan Markle's wedding in May - just three weeks after the Duchess had given birth.

If that doesn't warrant a citrine ring, we don't know what does.
