American fashion designer Nicky Hilton Rothschild has announced the launch of her customisable jewellery brand, Theo Grace, named after her daughters.

The socialite, who's the younger sister of Paris Hilton, commented 'I've loved making customised gifts for my friends and family since I was a little girl. I don't think there's a better gift than a one-of-a-kind, custom, bespoke piece of jewellery... I definitely plan on expanding Theo Grace. I think it could be an incredible destination for people to come for all things personalised'.
