What is Kate Middleton's engagement ring worth?
1 Answer

No one knows for sure what Kate Middleton's engagement ring is worth because that information hasn't been shared publicly. However, experts estimate the ring is probably worth between $300,000 and $400,000. The center stone is a 12-carat sapphire from Sri Lanka. Fourteen diamonds surround the stone within its 18-karat white gold setting. The ring has historical significance because it belonged to Prince William's mother, Princess Diana.
