A PALE YELLOW AND RUSSET JADE HOOF-SHAPED ORNAMENT, HONGSHAN Jade. China, Hongshan culture, c. 4700-2900 BC. Delicately worked with tapered sides widening to a sloped upper edge, the interior of one side subtly detailed with linear ridges and grooves. Pierced with two small apertures. The translucent stone of a pale-yellow tone with shadings of black and russet with dark-brown veining and milky white inclusions, an opaque area within the russet shading. 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 small hairline cracks over time. The elongated opaque area within the russet shading indicates the exact resting position of this piece in the tomb from where it was excavated. Large jade ornaments of this specific form were a product of the Hongshan culture, and examples have been recovered at the Niuheliang burial site in Liaoning province. While generally referred to as headpieces, Jenny F. So has recently suggested that they may have been worn on the forearm to protect the arm and wrist (Jenny F. So, Early Chinese Jades in the Harvard Art Museums, Cambridge, 2019, page 74). She cites an example worn on the forearm of the occupant of Site III at Niuheliang, and another recovered from the Bronze Age burial site at Dadianzi, in present-day inner Mongolia.

So 近年提出它們可能是戴在前臂上以保護手臂和手腕（Jenny F. So, Early Chinese Jades in the Harvard Art Museums, Cambridge, 2019, page 74）。 她舉了一個戴在牛河梁三號墓主前臂的例子，另一個是在今內蒙古大甸子青銅器時代墓地發現的。 重量：211.0 克 尺寸：高13.7 厘米, 寬 7.7 厘米 文獻比較：一件出土於牛河梁墓的箍形器可見於北京故宮博物院展覽。另一件可見於舊金山亞洲美術館，編號 B60J226。 拍賣結果比較：一件紅山文化箍形器，相近尺寸，見巴黎蘇富比 Early Chinese Jade and Hardstone Carvings，including The Collection of Max Loehr，2016年12月15日，lot 23，售價EUR 367,500；一件相似箍形器，帶有相似的玉色和尺寸，幾乎一模一樣的内壁和凹槽，同樣為紅山文化，見香港蘇富比Monochrome，2020年7月 11日，lot 136，售價HKD 937,500。
