Lot 166. A magnificent Ottoman jade and gem-set metal casket, Turkey, 17th-18th century. Estimate 40,000 — 60,000 GBP. Photo Sotheby's

Note: The abundance of multi-coloured gemstones combined with jade and highlighted by finely incised silver-inlaid foliate vines provides this casket with a lavish effect of wealth and opulence. This technique, of using floral collared gems linked by a grid of inlaid metal tendrils, became popular at the Ottoman court from the sixteenth century onwards and all manner of objects, including vessels, jewellery and weapons were decorated with gem-encrusted hardstones (see Rogers and Ward 1988, nos. 63 and 71).

A box most probably from the same workshop, or working in same taste, was sold at Christie's, 8 October 2015, lot 90, and another in these rooms, 7 October 2009, lot 192. Two mirrors displaying a similar aesthetic, examples of which can be seen in the Topkapi Palace Museum, sold in these rooms, 7 October 215, lot 414 and 25 May 2005, lot 208.
