This is a very fine and rare 18th or 19th century white jade sutra plaque. It was made from a very fine piece of mutton fat white jade of an even and very pale milky white tone. It was skilfully carved in intaglio and gilt with the Chinese version of Prajnaparamita Hridaya Sutra, the Heart Sutra on both sides translated by the famous Tang dynasty monk, Xuanzang. Jade is such a hard material that it is extremely difficult to carve the Sutra on a plaque of this size. Yet the carvings are excellent and the handwritings look as great as those by calligraphy masters. Its superb quality indicates that it was made for the court or aristocracies. It is in excellent condition with minor gilt wear. Date: AD 1750 - 1850; Length: 6.35cm, Width: 4.55cm, Thickness: 0.75cm; Condition: Excellent with minor gilt wear to the characters, made with a flawless piece of jade with an even and attractive tone; Provenance: Christie's, London.
