A necklace designed by Kate Middleton is to be re-released.

The future British queen - who announced her engagement to Prince William in November ahead of a wedding in April - has previously worked for retailer Junior Jigsaw, who are now planning to release a pendant necklace created by her to commemorate the romance.

Jeweller Claudia Bradby told People magazine: "Kate was very clear in what she wanted. She wanted a very simple bean pendant that a mother and daughter could both wear together. It was completely her initiative because she thought there was a gap in the market for something real and sophisticated, that had longevity for that age group.

"She is a classy girl and I genuinely remember thinking that William was very lucky to be going out with her - I thought she would be a huge asset to the royal family one day."

It was reported last week the 28-year-old beauty had chosen British designer Bruce Oldfield to design her wedding dress for the April 29 nuptials.

Fashion star Ben de Lisi said: "There are lots of rumours, but I've heard it is Bruce Oldfield.

"I'm absolutely certain I won't get chosen; I'm sure I'm not in the running."
