宋至元 白玉鏤雕四瓣菱形出廓如意雲龍紋飾

skilfully and precisely reticulated in the form of a writhing dragon within a quatrefoil border decorated with a ruyi motif to each of the four rounded outer edges, the mythical beast depicted with an undulating body amidst dense designs of leafy stems and ruyi scrolls, the lustrous white stone with tiny faint russet inclusions

白玉質，片狀，四瓣菱形。四角出廓飾如意紋，內雕一龍遊弋於靈芝仙草中。

此器雕工細膩，紋飾繁而不亂，充滿動感。
