The Engagement Rings
The engagement ring that Prince William presented to Kate Middleton once belonged to William’s late mother, Princess Diana. Now valued at $400,000, the 12-carat ring features an oval blue sapphire with cut faces. It’s circled by stunning solitaire diamonds.

Meghan’s engagement ring also features jewels from Princess Diana’s collection, with two of her diamonds framing a center stone that Prince Harry purchased from Botswana, where the now-married couple first fell in love. Meghan’s engagement ring is worth an estimated $350,000.
