You may have missed the Pearls exhibition but The V&A (Victoria & Albert) has one of the finest and most comprehensive collections of jewellery in the World.
Over 3,000 jewels tell the story of jewellery in Europe from ancient times to the present day; from a great gold Celtic breastplate to medieval love rings and pendants; from jewels by Cartier to animals by Fabergé; and jewellery by an international selection of contemporary makers. It is where jewellers and goldsmiths today often go for inspiration.
Open 10am to 5.45pm (or 10pm. Fridays) www.vam.ac.uk it is well worth a visit.
