Literature comparison: Compare a closely related jade bowl, of near-identical material showing gray veins running diagonally through the stone, but of slightly larger size and incised with a Jiaqing four-character mark, illustrated in Lord Jiaqing and the Journey to Taiwan: A Special Exhibition on Cultural Artifacts of the Qing Emperor Renzong, National Palace Museum, Taiwan, 2016, pp. 260-261, no. III-24. The author notes that the gray jade is from the Xinjiang region, that several gray Islamic-style jades are in the collection of the National Palace Museum but only a few have reign marks, and that of the jade tribute items submitted from Kashgar in 1817, there is a two-handled gray-jade bowl of similar quality.

Auction result comparison: Compare a near-identical bowl, also with a Qianlong mark, but dated 18^th-19^th century, at Christie’s New York in Fine Chinese Ceramics and Works of Art on 17 September 2010, lot 1113, sold for USD 21,250, and a closely related but slightly larger bowl, also with a Qianlong mark and of the period, at Sotheby’s Hong Kong in Fine Chinese Ceramics and Works of Art on 9 October 2007, lot 1584, bought-in at an estimate of HKD 400,000-600,000.
