Diamonds may be a girl's best friend, but silver may be a princess's.

Kate Middleton's sterling silver necklace she designed in 2007 is once again for sale. The Silver Bean pendant with rose quartz and pink pearl charms is available for £46 (about $70) at The reissued piece comes in the footsteps of the re-releases of Middleton's engagement portrait outfits.

While working as a buyer for British retailer Jigsaw, Middleton created the silver charm necklace with designer Claudia Bradby.

"When I read that [Kate] 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, whose husband, Tom, conducted the royal couple's first television interview, said in a statement.

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