Emerald intaglio ring

The rectangular emerald intaglio carved with an inscription borderd by decorative elements, measuring approximately 20.0 by 17.0 by 3.4 mm., within a silver and gold mounting engraved with flowers and scrolls, mounting probably Chinese, 19th Century, size 6½.

The intaglio's inscription mentions the name David Jolie (or Jolly) Burton and is dated 1200 (AD 1785-6). Although the mounting could conceivably have originated in China or Japan, it is more likely to be Chinese, made for an ex-patriot in Shanghai, due to the abundance of  trading activity between Shanghai and Calcutta in the 19th century.
