When Prince William proposed to Kate Middleton at the foothills of Mount Kenya, the royal used his late mother’s engagement ring to pop the question.
Princess Diana was gifted the extravagant item of jewellery by Wills’ father, Prince Charles, in 1981.
And now, 36 years later, the stand-out accessory is worth a staggering amount of money.
In 2017, the Duchess of Cambridge’s ring is valued at an eye-popping £300,000.
Which is a lot more than the average person spends on an engagement ring, as we’re sure you can guess.
The ring is made up of 14 solitaire diamonds surrounding a 12-carat oval, so it’s hardly surprising the ring is valued so highly.

But when Prince Charles first bought the presented number, it was valued at £28,500.
Which in relative value for the time, would have been an over £100,00 according to Bank Of England’s inflation currency converter.
In true Diana style, she was actually the one who chose the famous ring back in 1981, not her then-fiancé.
She chose it from a selection of rings shown to her by then crown jewellers Garrard of Mayfair.
Diana opted for one a design the public could also buy – unusually it wasn’t custom made.
But before being passed on to William, it was initially Prince Harry who was in possession of iconic ring.
However Harry, who is thought to be planning a proposal to Meghan Markle, chose the iconic engagement ring, and William his mother’s Cartier watch as keepsakes after her tragic death in 1997, a source told the Daily Star.
It was agreed among the princes that whoever got engaged first would pass on their mother’s stunning ring to their bride.
