VERY INTERESTNG EARLY CHINESE CARVED YELLOW JADE MASK BI DISC PENDANT MING OR EARLIER. A very interesting example that came with archaic jade collection. Very conservatively dating to the Ming dynasty, our personal opinion is the disc is likely much older. Size: The disc measures 2 1/8 inches wide, by 1/2 of an inch thick. The disc weighs 39.2 grams. Condition: Minor imperfections consistent with ancient age. Overall substantially good as seen. Please see pictured condition and the images are also part of description. Domestic shipping, packing service and insurance: $55.00
