The Duke of Cambridge is said to have thought long and hard about what to present his wife with, and has settled for a stunning piece of jewellery, according to reports.
"William has been giving this a lot of thought for a long time," an insider told Express. "He's got lots of ideas from studying history of art at university and decided on a pink diamond as a centrepiece because it is pretty and feminine. It will be a thank you present to Kate."
The present is thought to be a special brooch adorned with a pink diamond, and William is said to have been involved with the design.
When the first-time father proposed to Kate, he presented her with his late mother Princess Diana's sapphire diamond engagement ring, which Kate is always seen wearing. To mark the birth of their son, it seems Prince William has decided on a unique and even more personal piece of jewellery.
Despite the royals parents asking friends and family for donations to charity instead of material gifts, Prince William and Kate have been showered with presents from well-wishers around the world who are eager to celebrate the birth of Prince George.
Prime minister David Cameron and his wife Samantha gave the royal baby a box-set of Roald Dahl books including George’s Marvellous Medicine, Charlie and the Chocolate Factory and Matilda, while deputy prime minister Nick Clegg and his wife Miriam sent a hand-embroidered blanket made by nuns from a convent near Miriam's hometown of Valladolid in Spain.
Perhaps the most unique gift was from a pub in Cambridge that William and Kate visited last year in the early stages of the Duchess' pregnancy. The Greene King Pub the Fort St George of the small town have permanently reserved a seat for Prince George and marked it with a plaque.
"We want the family to know they are very welcome to come back any time, and there will always be a reserved space for the royal baby," said pub manager John Cecchini. "As he gets older, we will make sure the seat under the plaque grows with him."
