It’s never too early to start planning! While Prince William is still second in line to the throne behind dad Prince Charles, he and wife Kate Middleton may already be preparing for their new new roles as king and queen. Since everyone is all about diamonds, we of course all have to know about the crown that will one day grace the Duchess of Cambridge’s head.

“Kate will be crowned alongside William at his coronation in Westminster Abbey,” Paul Burrell, a former butler of Princess Diana, told Us Weekly. “She’ll be crowned queen consort, much in the same way the Queen Mother was [to Queen Elizabeth II’s father, George VI.]”

According to the outlet, the crown Kate, 37, will wear was made back in 1937 by jeweler Garrard & Co. If you ask us, it’s not too shabby looking at all. It is decorated with about 2,800 diamonds, including a 105-carat Koh-I-Noor diamond that serves as the centerpiece. Don’t know what any of that means? Just know that it is one very, very valuable piece of headwear. The stone at the center of this lovely crown has quite the history behind it, too, as it was first presented to Queen Victoria in 1851, becoming part of the Crown Jewels collection upon her death.

Prior to it falling into the Queen Mother’s hands, it was used by Queen Alexandra and Queen MaryTake a look at it below!

While it isn’t known exactly when the mother-of-three will officially become the new queen, the 92-year-old head monarch is reportedly already preparing Kate for the job. “She’s really taken Kate under her wing,” royal expert Rebecca Long dished to the outlet. “The two of them will often spend hours discussing royal life and the future of the monarchy.”

We can’t wait to see this beautiful crown on Kate one day.
