Have you been naughty or nice this year? The king of tongue-in-cheek jewellery, Theo Fennell's eponymous brand has become something of a British treasure since its launch in 1982, with every piece of jewellery and silverware meticulously handcrafted in the workshops above Fennell's flagship Fulham store. His 'Art Devil pendant in 18ct white gold is a classic example of his fun approach to fine jewellery. Designed to be worn on a charm bracelet, it is part of the typically colourful 'Art collection, which takes a heart and transforms it into a multitude of characters, from a yellow-sapphire-studded leopard to a brown-diamond-set giraffe. Wickedly charming, Theo Fennell's 'Art Devil pendant in 18ct white gold, set with 1.75ct pavé rubies, can be worn alone or combined with other charms from the 'Art collection.
