There's a nice exhibition of conceptual jewellery at the Renew Rooms in Wood St. until August 10th 2006.
10 members of the Manchester Jewellers Network each made a piece which was inspired by some Manchester architecture. The works were displayed at Urbis during Architecture Week and received excellent reviews before moving to the RIBA showroom here in Liverpool.

Pictured here is Toby Cotterill's work inspired by the Castlefield railway viaducts. The pieces on the top actually move along like a little train.
