Kate Middleton's iconic engagement ring
Kate Middleton's engagement ring is now worth a whopping £300,000 – ten times the amount it was valued at in 1981, when Prince Charles bought it for Princess Diana.
Comprised of 14 solitaire diamonds that surround a 12-carat blue Ceylon sapphire, the inherited ring is definitely one of the most famous in the world.
Meanwhile, the Queen's ring is valued at £100,00 – worth just a third of Kate's.
But the royal sparklers are worth little compared to Beyonce and Kim Kardashian's rings, which are valued at a jaw-dropping £5.8 million and 5.15 million respectively.
