AN EXCEPTIONAL SPINACH-GREEN JADE CONG, LATE SHANG DYNASTY China, Anyang period, c. 1300-1050 BC. With plain sides and shallow circular collars, the translucent stone of a spinach-green tone with icy veins and dark speckles. Provenance: From the private collection of Professor Filippo Salviati, Rome, Italy. A professor of archeology and art history at the Italian Institute of Oriental Studies at the Sapienza University of Rome, Prof. Salviati has researched and published extensively on Chinese archaic art. Condition: Excellent condition with minor wear, the stone with few natural fissures, some of which may have developed into microscopic hairline cracks over time. Weight: 349.3 g Dimensions: Size 9.1 x 9 x 4 cm Expert's note: The present jade cong is an exceptional masterpiece, featuring a spectacular combination of plain form, a near-perfect mineral of true spinach-green tone and varying translucency, skillful use of the subtle variegation of color, all to emphasize and intensify the magnificent interplay of natural sunlight as it shines on and passes slowly through the jade. Examples where the lapidary was in such total control of the medium, despite its remarkable hardness, are rare. The jade has been tested and measures between 7.0 and 8.0 on the Mohs hardness scale. Literature comparison: Compare a closely related jade cong in the collection of the Los Angeles County Museum of Art, accession number M.89.156.4. Note the spectacular interplay of light which is very similar to the present lot.
