It’s a royal rock brigade! Prince Harry and Meghan Markle announced their engagement at Kensington Palace on Monday, November 27, and debuted Markle’s stunning ring to seal the deal, sending us all into Royal Wedding mania. And now, with their wedding fast-approaching at Windsor Palace on Saturday, May 19, we all have royal bling on the brain. And that means it’s time to take a gander at the truly spectacular royal engagement sparklers of the last century, including Markle’s future sister-in-law Kate Middleton‘s and Princess Diana‘s to Prince Harry’s cousin Princess Eugenie’s recently-received engagement stone that not so subtly references her mother’s engagement ring.
