Prince William to present Kate Middleton with her own sparkly new tiara when she's a mum
Kate Middleton has been enjoying a tropical holiday
Prince William is planning on spoiling the mother of his baby
Prince William has received permission from Queen Elizabeth II to create new jewels
Kate Middleton and Prince William escaped to the tropical island last week - along with Kate's mum Carole and dad Michael Middleton - to unwind ahead of their move to Apartment 1A, the 21-room flat within Kensington Palace, later this month.
When they aren't in Anglesey, the couple have been staying at Nottingham Cottage on the grounds of the Palace while Apartment 1A undergoes a £1 million renovation.
The break was sorely needed by Kate, 31, who suffered severe sickness in the early stages of her pregnancy.
She's now putting her energy into her official Royal duties, with no less than four engagements this week and next.
And while it might be tough work for Kate, Wills is certainly making sure she'll be spoilt rotten when she gives birth in July.
He wants to treat the Duchess of Cambridge to a luxury villa on Mustique - which he'll purchase from his own private funds - and also plans to present her with a new set of crown jewels after the baby's born.
In the past, Kate's borrowed regal jewellery to wear to official engagements, but our source explains: 'He'll commission a new set to celebrate the birth of their first child, having already received permission directly from the Queen.
'Kate will be given a sparkly new tiara, earrings, bracelets and rings, which she'll wear
for significant occasions - most importantly when William finally ascends to the throne.'
The Royals usually commission jewellers G Collins & Sons Limited to create lavish gems as wedding gifts but for her nuptials in 2011, Kate wore the Cartier Halo tiara made for the Queen Mother in 1936.
Our source reveals: 'William thought this would be the perfect time for Kate to have something of her own instead.'
