A RARE HONGSHAN CULTURE JADE ‘XUANJI’ (ARCILLARY DISC)
C. 4000–3000 BC
红山文化 玉璇玑
ESTIMATE: $2.000– $3.000
Description
This exceptional jade xuanji, or toothed arcillary disc, is a classic ceremonial object from the Hongshan Culture of the Neolithic period. The disc features a central circular aperture and is characterized by its three distinctive projecting flanges or “teeth” radiating from the perimeter in a dynamic, swirling motion. These notched projections are masterfully carved with subtle, rounded edges, reflecting the primitive yet sophisticated lapidary skills of early Chinese civilizations.
The jade material exhibits a translucent pale celadon-green hue, heavily suffused with characteristic “chicken-bone” white calcification and russet-colored iron inclusions from long-term burial. The surface is polished to a soft, waxy luster, with slight undulations and an uneven thickness that thin toward the outer serrated edges—a hallmark of authentic Hongshan hand-grinding techniques.
Dimensions
• Diameter: 4.8 cm
• Thickness: 0.4 cm
• Weight: 13.0 g
CONDITION REPORT
The jade xuanji is in overall excellent condition for its age. The stone displays significant natural alteration and mineralization consistent with its Neolithic origin, including characteristic pitting, surface erosion, and calcification. There are minor age-related nicks along the delicate edges and traces of earth encrustation. No modern professional restorations or structural fractures were observed.

红山文化 玉璇玑
描述
此件稀有的玉璇玑是典型的新石器时代红山文化礼器。其造型呈圆环状，中心对钻圆孔，外缘顺时针方向延伸出三个呈旋涡状的齿突，线条流畅且具动感。璇玑的棱角打磨圆润，体现了中国早期先民质朴而高超的制玉技艺。
玉材呈青白色，因数千年的深埋，表面呈现出明显的“鸡骨白”钙化现象，并伴有天然的褐色铁锈沁色。玉质表面带有温润的蜡状光泽，厚薄略显不均，且向边缘处逐渐收薄，呈现出红山玉器手工研磨而成的微妙起伏感。
