Few pieces of Victorian jewellery have survived in such sparkling condition as this Kashmir sapphire and diamond necklace which sold at Dreweatt Neate’s Donnington Priory saleroom near Newbury last week for £240,000 (plus 15/10% premium) – the highest ever price for jewellery at a provincial saleroom.

“It was like the 1970s all over again,” said John Benjamin of Woolley and Wallis, describing the breadth of quality at his jewellery sale in Salisbury on April 24-25.

THE Prince of Wales feathers to this Victorian gold fringe necklace, right, revealed that it was manufactured by Robert Phillips of Cockspur Street, London, whose signature the royal feathers were, but it may as well have been the work of any number of designers working in the Etruscan Revival style during this period – Carlo Giuliano, John Brogden or Augusta Castellani.
