This small brushwasher is sensitively worked. The carver has skilfully used the natural shape and colours of the pebble to achieve a powerful natural effect, while observing restraint in the overall composition. This pursuit of naturalism in the carving of jade objects, combined with detailed modelling, is characteristic of the Ming dynasty. Compare with a similar vessel illustrated by James Watt, Chinese Jades from Han to Ch'ing, New York, 1980, p. 133, no. 110; and another lotus-leaf-shaped washer with a frog in the centre, from the Qing Court collection, illustrated in Jadeware (II), The Complete Collection of Treasures of the Palace Museum, Hong Kong, 1995, pl. 159.
