Add a pop of colour to your outfit with this Bell ring by London-based Robinson Pelham. Established in 1996 by Kate Pelham Burn, Vanessa Chilton and Zoe Benyon, Robinson Pelham creates luxurious pieces with an emphasis on coloured gemstones. The jewellery brand hit the headlines in 2011 when it was commissioned to design the diamond earrings worn by Kate Middleton and her sister Pippa at the Royal Wedding. Seamlessly spanning the divide between classic and fashionable, this Bell cocktail ring combines the warm glow of yellow gold with a pastel-coloured cabochon of blue chalcedony. Also available in green prehnite.
