拍品描述

Dimensions: Length 11.5 cm (4.53 in / 0.38 ft); Width 10.8 cm (4.25 in / 0.35 ft); Late Neolithic Period, 5th–3rd Millennium BCE，Weight: 139 grams (4.90 oz)，Condition & Provenance: The jade bi is preserved intact overall, with no apparent major breaks or restoration. The stone has undergone extensive calcification, resulting in a predominantly chicken-bone white surface enriched by warm cream-yellow, gray-brown, and gray-white areas of coloration. Fine hairline and network-like weathering fissures extend across the body, creating a richly layered and naturally aged appearance. The object is fashioned in a distinctive rounded-square bi form with a large circular central aperture. The interior wall of the aperture retains visible rotational and abrasive-working traces, while a smaller suspension perforation near the upper edge provides an additional means of attachment. The inner and outer contours have been extensively ground and polished, producing softly rounded corners and smooth transitions without sharp edges. The surface retains a substantial matte-to-waxy patina with pronounced variations in texture and coloration. Provenance: Private Collection, Switzerland. Acquired in 1994 and retained in the same collection for approximately thirty-two years. According to the collection history, the piece previously circulated through the European art trade, including dealers in France and Germany, before entering the Swiss collection in the mid-1990s.Description: This substantial jade bi is fashioned from a single piece of stone into a broad, rounded-square form centered by a large circular aperture. At 11.5 cm in length and weighing 139 grams, the object has considerable physical presence, yet its design remains remarkably restrained. Its visual impact comes primarily from proportion, negative space, surface character, and the contrast between the softly squared exterior and perfectly legible circular opening.
