1. IT'S CONNECTED TO ROYAL HISTORY 

The gorgeous 12-carat blue sapphire ring was inspired by a brooch Prince Albert had gifted Queen Victoria before their own wedding. She loved it so much she wore it as her "something blue" in the front of her wedding dress.

2. IT BELONGED TO PRINCESS DIANA FIRST 

Princess Diana had chosen the ring out of a few rings Prince Charles had selected to be her engagement ring. It was made by the British jeweler Garrard and was a part of their stock collection.

3. IT BROKE ROYAL TRADITION

The ring was chosen from the jeweler's stock, which meant that anyone who could afford the piece could purchase it. It broke tradition because it was not a custom bespoke piece. 

4. IT HAS A UNIQUE COMPOSITION

Kate Middleton and Prince Diana's ring is a gorgeous piece to look at. It is made up of a 12-carat blue sapphire stone, 14 solitaire diamonds set in 18K white gold.

5. DIANA'S JEWELRY WAS LEFT TO HER CHILDREN

Princess Diana made sure to leave her personal jewelry to her two sons, Prince William and Prince Harry. She left the decision of who would get what piece up to the boys. 

6. PRINCE HARRY CHOSE IT

Prince Harry had claimed his mother's engagement ring when she passed. He had picked it as he remembered holding his mother's hand and how it would hurt him as a small boy. Prince William chose her gold Cartier watch.

7. HARRY GIFTED THE RING TO HIS BROTHER

Prince Harry had gifted the ring to Prince William, as he felt that it would be "fitting" if William proposed to Middleton with the gorgeous ring so it could sit on the throne when William becomes King. 

8. IT WENT ON AN INTERESTING ADVENTURE

Prince William revealed that the very expensive ring had sat at the bottom of his rucksack for three weeks before he proposed to Middleton in Kenya. He had carried it around with him so it would not be lost.

9. MIDDLETON ALTERED THE RING

Shortly after accepting William's proposal, Middleton got her late mother-in-law's ring altered. The jeweler G. Collins and Sons resized the ring by adding small platinum beads on the ring's interior to reduce the diameter. 

10. THE RING'S WORTH GREW

According to various reports, when the ring was purchased in the 80s, it cost between £28,000 and £47,000. However, it is estimated to cost £390,000 but is priceless due to its history and connection to the royal family.
