Wan Yi, Yang Shuqing and Lu Yanzhen in Daily Life in the Forbidden City, Beijing, p.163, fig.223, note that 'during the Qing dynasty articles made of rose-quartz were often presented to the emperor as tribute by high officials. However, very few of them are still preserved in the Qing palaces'. See a related rose-quartz incense burner, in the Palace Museum, Beijing, illustrated in Classics of the Forbidden City: Life in the Forbidden City of Qing Dynasty, Beijing, 2007, no.220.

The deeply rounded shape of this bowl with a sharply cut circular foot ring is characteristic of the Qianlong period; see a related pair of white jade bowls, incised Qianlong four-character marks and period, which was sold at Bonhams Hong Kong, 30 May 2017, lot 115.

Compare with a related rose-quartz tripod incense burner and cover, 18th/19th century, which was sold at Bonhams London, 17 May 2012, lot 228.

碗尖唇，侈口，直腹斜收，圈足略外撇，色如芙蓉，半透明，石理如花瓣經脈，通體光素，碾磨精當。
