The shape of the present teapot is highly unusual, as it owed much of its form to the virtually flawless natural material of the jade rendering it unique. It is interesting to note the main body which is reserved without any form decoration whilst cleverly working the natural minute inclusions into an overall design of the moth-like insect around the area of the spout. Its workmanship is a testament of the expertise of the master carver. Compare with a related white jade lobed teapot with a rams-head spout, also inscribed with the reign mark, Jiaqing Yuyong, in the Qing Court collection, Beijing, illustrated in Jadeware, III, Commercial Press, Hong Kong, 1995, p. 262, no. 216.
