Alan Vallis is a jewellery designer and maker and was one of the original tenants to move into the OXO Tower Wharf, on London’s South Bank, in 1996. Often working on commission, his work is inspired by the decorative textures, colours and patterns of the Middle East, in particular, seen in his stacking rings and multi-stone combinations.
