A Qianlong Falangcai porcelain bowl estimated to fetch in excess of $25.6 million was previewed by Sotheby's on August 30 in Hong Kong.
The auctioneers claimed the bowl is one of the most significant examples of Qianlong Falangcai in private hands, and the only recorded example of its design outside of the National Palace Museum, Taipei.
Qianlong refers to Emperor Qianlong who ruled during the 18th century, while Falangcai usually refers to a decoration style which uses foreign-imported enamels.
The bowl, which was produced during the Qing dynasty, was fired in Jingdezhen in the south of China and sent to the emperor in Beijing.
It will go on auction in October.
