For 16 years Vanessa Chilton, Zoe Benyon, and Kate Pelham Burn — the founders of custom jewelry company Robinson Pelham — have been running their business as an appointment-only operation. But it seems as if the Kate Middleton Effect has prompted the trio to set up a retail location, which is slated to open on November 5 in London’s upscale Kensington neighborhood, reports the Telegraph.

Robinson Pelham made a splash at the Duchess of Cambridge’s spring 2011 wedding to the Duke of Cambridge when the Duchess’s parents commissioned the jewelers to create pieces, including Kate’s diamond oak leaf and acorn earrings. Robinson Pelham also created Pippa Middleton’s diamond drop earrings, Carole Middleton’s tourmaline and diamond pendant and earrings, and an oak leaf and acorn gold stick pin for Michael Middleton and James Middleton.

The new store will continue to provide Robinson Pelham’s custom design service and will introduce six ready-to-wear collections. The jeweler will also educate customers about their own jewelry or help them reconfigure antique jewelry into more contemporary pieces. We’re sure that the store won’t have any problem attracting customers, since it has already made jewels fit for the future Queen of England.
