Long before Prince William had the chance to offer the ring to his future bride, it belonged to his mother, the late Princess Diana.
While the exquisite sapphire and diamond ring has inspired thousands of engagement ring designs since, it wasn’t always looked upon fondly.
At the time of Diana’s engagement to Prince Charles in 1981, the ring had received the nasty nickname of ‘the commoner’s ring’.
Diana herself wasn’t a ‘commoner’ (like Kate and Meghan Markle were before marrying into royalty), a term which refers to members of the public who are not within the aristocracy.
She was actually born Lady Diana Spencer, a blue blood aristocrat through and through.
So why was the ring branded ‘common’?
The reason comes down to the fact Diana picked the ring from a catalogue, which any ‘commoner’ could have done.
Prince Charles didn’t propose to Diana, who was just 19 at the time, with a ring, but allowed his future bride time to browse for which sort of ring she’d like.
