The Water, Pine and Stone Retreat Collection - Objects Of Contemplation Single-Owner Sale totalled HK$41 million/ US$5.2 million. An Imperially Inscribed Bamboo-Veneer Ruyi-Sceptre, Qianlong Period sold for HK$15.8 million / US$2 million, achieving a world record for a carved bamboo and a ruyi-sceptre at auction. This exceptional ruyi sceptre ranks among the finest sceptres produced for the personal enjoyment of the Qianlong Emperor and is in itself a masterpiece of bamboo-veneer technique. The present example, with its thin section and its elaborately controlled naturalism, pushes the technique to its absolute limits. No similar example is known, although other ruyi sceptres made of bamboo veneer can be found for example in the collection at the Palace Museum Beijing.
