A gilt-metal, rock crystal, amethyst, rose quartz, chalcedony and cameo-mounted coffret a bijoux, a jewellery casket, is seen as part of the 500 Years: Decorative Arts Europe collection at Christie's auction house in New York April 16, 2010. Less than two years after an unusually long-lived art boom came to an end with lower prices and a decreased supply, bidders have returned to salesrooms, prices are mostly ticking up and records are being set once again.
