Since announcing their engagement in November everyone has been buzzing over Prince Harry and Meghan Markle's upcoming royal nuptials.
But the couple have already broken a royal 'rule' with her engagement ring - and one that is strictly followed by the rest of the monarchy.
Yep, it's royal protocol engagement rings should always contain a coloured gem stone.
However, the 36-year-old actress' ring contains all diamonds.
The stunning diamond ring - designed by Prince Harry himself - is set on a yellow gold band.
The centre stone of the ring is from Botswana, with two diamonds on the band surrounding the center one coming from the late Princess Diana’s personal jewelry collection.
Created by Queen Elizabeth II’s preferred jeweler, Cleave and Company, the ring is estimated at 6.5 carats in total, with the center diamond at roughly 5 carats.
Prince William gave Kate Middleton the 18-carat sapphire and diamond ring that once belonged to his mother.
The engagement rings of The Queen Mother and Princess Anne also feature a sapphire.
While Sarah Ferguson was given a ruby ring, as was Princess Margaret.
