A CELADON AND GREEN JADE BI DISC, WARRING STATES TO HAN DYNASTY China, 475 BC-220 AD. Neatly carved on both sides in low relief with a tightly spaced 'grain pattern' of hexagonal bosses with beveled sides formed by a grid of intersecting lines, all between incised line borders at the rim and around the central aperture. The translucent stone is of a mottled celadon and dark-green tone with black speckles and cloudy white inclusions. Provenance: Collection of Robert Rousset (1901-1982) and thence by descent to the present owner. Robert Rousset was a former radio officer in the merchant navy. He is one of the most prominent French pioneers of the Chinese art market in Paris. As a child, his father, an insurance agent, would take him to Hôtel Drouot where he started to buy at a young age. His true passion for Asian art started in the 1920s, when he was sent on a mission to Beijing after the decline of the Qing empire, along with Osvald Siren, the famous Swedish Asian art historian and connoisseur. He then became one of the main contributors of Chinese antiques for the Compagnie de la Chine et des Indes, founded in Paris in the early 20th century by the Blazy brothers. After the 1929 stock market crash, he had the opportunity to acquire the company. With his sister Suzanne in charge of the porcelain, they developed the business and became one of the most important dealers in France, selling pieces to the greatest museums, including the Musee Guimet and the Metropolitan Museum of Art.
