Prince William is always very thoughtful when it comes to choosing presents for his wife, Kate Middleton (well, not counting the time he got her the worst gift).

He often opts for pieces of jewellery, which include an eternity ring he picked out after Prince George was born, as well as some green amethyst earrings, for their first Christmas as newlyweds.

And it turns out he may have a soft spot for a precious stone, which he has gifted her in the past. As you might have guessed, it's the sapphire.

The Duke reportedly bought his wife a pair of sapphire earrings this Christmas, and it's not the first time he incorporated the stone in jewellery.

For their third wedding anniversary, he got the Duchess a Cartier Ballon Bleu watch, which in itself was a small nod to his late mother, Princess Diana, as one of her favourite watches was the Cartier Tank Français style, which he is said to have inherited from her after she died.

AS for the Ballon Bleu watch, he had a sapphire added to the frame of the dial. As for why he likes the stone, it seems there is a simple explanation.

It is the one that matches Kate's iconic engagement ring best.

Penny grew up in France and studied languages and law at the Sorbonne Nouvelle University in Paris before moving to the UK for her MA in multimedia journalism at Bournemouth University. She moved to the UK permanently and has never looked back (though she does go back regularly to stock up on cheese and wine).

Although she's always loved fashion - she used to create scrapbooks of her favourite trends and looks, including Sienna Miller and Kate Moss' boho phase - her first job was at MoneySavingExpert.com, sourcing the best deals for everything from restaurants to designer sales.

However she quit after two years to follow her true passion, fashion journalism, and after many years of internships and freelance stints at magazines including Red, Cosmopolitan, Stylist and Good Housekeeping, landed her dream job as the Digital Fashion Editor at Marie Claire UK.

Her favourite part of the job is discovering new brands and meeting designers, and travelling the world to attend events and fashion shows. Seeing her first Chanel runway IRL at Paris Fashion Week was a true pinch-me moment.
