On 16th November, 2010, Clarence House announced that Prince William and his girlfriend, Catherine Middleton, were engaged. Royal fans rushed home to switch on BBC News to find out every detail. For jewellery lovers, the story had additional intrigue: Kate Middleton had received a very special engagement ring from Prince William.

Here are 10 fascinating facts about the world’s most famous blue sapphire ring.

1. Poignant meaning

The sapphire ring that William gave his now wife; Catherine, the Duchess of Cambridge; has deep personal meaning for him.

It previously belonged to William’s mother, Princess Diana, who died an untimely death in a car crash in August 1997.

Prince William said at the time of his engagement that giving the ring to Catherine was his way of making sure his mother didn’t miss out on his wedding day.

2. Carats, Carats, Carats

The ring consists of a 12-carat oval blue sapphire, cut into facets, and surrounded by fourteen solitaire diamonds.

The ring’s setting is made from 18K white gold.

3. Resized for Catherine

When Catherine Middleton received the ring, it was slightly too big for her.

It kept sliding and turning around on her finger, so the Crown Jeweller, G. Collins and Sons, were asked to resize it from size I to H.

They did this by placing small platinum beads inside the ring’s band.

4. Royal blue engagement outfit to match the ring

When Kate and William were interviewed on television a few hours after the engagement had been announced, Kate wore a sapphire-blue silk jersey dress, cleverly matched with her engagement ring’s colour.

The dress was made by ISSA, a London designer who the Duchess of Cambridge loves. After the engagement announcement, the dress sold out in a matter of hours.

(UPDATE: In March 2018 the dress became available again at House of Fraser.)

5. From Diana to Charles, Harry to William

After Prince William’s and Prince Harry’s parents, Prince Charles and Lady Diana, divorced; Diana returned her engagement ring to her ex-husband. It was stored in Kensington palace.

After Diana’s tragic passing away, Prince Charles allowed his two sons, William and Harry, to select mementos from her possessions.

Harry, the younger brother, picked the engagement ring, while William chose a gold Cartier watch.

But when William took the decision to propose to Kate, the brothers exchanged their mementos.

It’s said that Harry thinks of Kate fondly as a sister and that both princes wanted her to have their mother’s ring.

6. “Commoner’s sapphire”

William’s mother, Lady Diana Spencer, originally chose the ring herself. Prince Charles did not propose with it in hand, but instead had a selection of rings shown to her.

At the time, Diana’s choice caused a scandal. Some people criticised her for picking a pret-a-porter ring, instead of having one custom made.

Some newspapers went as far as calling it a “commoner’s ring”.

7. Now the most coveted sapphire ring style in the world

Despite the initial criticism for her choice of ring, Princess Diana quickly became known as a style icon. Her hairstyle, outfits and of course, her ring, were copied by millions all over the world.

Consequently, the “commoner’s sapphire” became the world’s most sough after engagement ring style for more than a decade.

When William and Catherine announced their engagement in 2010, sales of sapphire engagement rings went through the roof once more, with jewellers all over the world frantically buying hoards of the blue gems to satisfy the public’s demand.

8. Ten-fold increase in price

The ring was originally created by Garrard & Co., the former Crown Jeweller.

At the time, in 1981, it cost £28,000. It’s now valued at approximately £300,000.

9. In a rucksack to Africa

William had decided to propose to Catherine during the couple’s trip to Kenya during the autumn of 2010.

He had the ring taken out of the royal safe and carried it around with him in his rucksack for three whole weeks in Africa until he finally popped the question!


10. Matching earrings and pendant

The Duchess of Cambridge was later seen wearing jewellery that matches her engagement ring.

It was at the time when she was expecting the couple’s second child, while attending a ceremony at St. Paul’s Cathedral to commemorate the withdrawal of British troops from Afghanistan.

The set includes a sapphire and diamond cluster necklace, and matching earrings.
