A green and yellow enamelled vase bearing the mark of the Yongzheng emperor (1678-1735) exceeded all expectations at Christie's Fine Chinese Ceramics and Works of Art sale on November 5 in London.
The vase, a similar example of which is currently housed in Beijing's Palace Museum, was expected to make £200,000-300,000, but saw spirited bidding to reach £3m ($4.9m) - a 916.8% increase in value.
Yellow and green enamelled porcelain was produced in the imperial kilns at Jingdezhen as early as the 15th century. This example is decorated with bats and clouds, wishing the owner good fortune.
