A RARE LIANGZHU CULTURE JADE DISC (HUAN)
C. 3300–2300 BC
良渚文化 玉环
ESTIMATE: $800– $1.200
Description
This substantial jade disc, or huan, is a definitive ritual object from the Neolithic Liangzhu Culture of the Yangtze River Delta. The disc features a characteristically large central aperture relative to its overall width, distinguishing it as a huan according to classical Chinese jade terminology. The stone is of a pale, translucent celadon-green tone, now largely transformed by millenniums of burial into a mottled, opaque cream and “chicken-bone” white calcification.
The carving demonstrates the primitive yet monumental lapidary techniques of the period, with a slightly irregular circular perimeter and a central hole that shows evidence of being drilled from both sides (bi-directional drilling). The disc exhibits a flat profile with soft, weathered edges resulting from centuries of natural erosion. The surface is suffused with dark russet and black inclusions, likely iron and manganese from the surrounding soil, which add to its profound archaic character.
Dimensions
• Diameter: 8.6 cm
• Thickness: 0.5 cm
• Weight: 70 g
CONDITION REPORT
The jade huan is in stable condition consistent with its Neolithic age. The surface exhibits extensive natural calcification, weathering, and characteristic pitting. Small nicks and minor erosion are visible along the perimeter and central aperture. No modern structural repairs or fractures were detected under standard visual inspection.

良渚文化 玉环
描述
此件沉稳厚重的玉环是长江下游新石器时代良渚文化的典型礼器。其特点为中心圆孔较大，孔径与边宽比例适中，符合中国古代玉器分类中“环”的定义。玉材原色呈淡青绿色，半透明，历经数千年的地下埋藏，现已大面积钙化，呈现斑驳的象牙白与“鸡骨白”色泽。
该器展现了新石器时代质朴而宏大的制玉工艺，外缘呈不规则圆形，中心孔壁可见明显的对钻痕迹。环体扁平，边缘因长年自然侵蚀而显得圆润古拙。玉环表面沁有深红色及黑色矿物质点，呈现出深沉的古玉神韵。
