Well, if the whole princess thing doesn't work out, Kate Middleton can always fall back on fashion design.

A necklace co-designed by Prince William's bride-to-be and jewelry designer Claudia Bradby in 2007 has been reissued to capitalize on the brunette beauty's popularity, the London Evening Standard reports.

Priced at a commoner-friendly 46 pounds ($71), the silver bean, rose-quartz and pink-pearl pendant for girls was originally sold at Junior Jigsaw shops when Middleton worked for the British chain as a junior fashion buyer during 2006 and 2007, according to the paper.

The future princess reportedly collaborated with Bradby on the design -- as well as its 14-inch chain and packaging -- after noticing a need for jewelry aimed at the juniors market.

"When I read that she was appointed as a buyer at Junior Jigsaw, I just wrote saying congratulations, and that if she wanted to do some real jewelry to get in contact," Bradby tells the paper.

"She phoned me back and said she had been thinking of doing a small pendant, and would I be interested?

"She was very specific about what she wanted. It was her concept.

"I thought it would be a good idea to reissue it to celebrate their engagement."

No kidding! Middleton has already sparked a shopping frenzy that's seen sapphire-and-diamond replica engagement rings flood the market, while her blue Issa engagement dress and its $25 knockoff have both sold out.

Hmmm... maybe she should start charging a commission?
