此洗採用黑白玉製成，玉質溫潤，黑白紋理自然相間，上下分明。白玉白若割脂，凝脂生輝，黑玉溫潤厚澤，凝蘊章華，拋光精到。整器隨型而作，器壁挖膛均勻，洗內深腹，壁內光滑。筆洗外壁通景高浮雕雲龍海水圖。海水於器底翻湧澎湃，波濤洶湧，群龍騰躍其上，威猛矯健。龍五爪，方頭闊嘴，龍睛怒突，不怒自威。龍首顙頂圓凸，此為長壽瑞徵。叉狀龍角沖天直立，鬃毛細如游絲，鬚髯當風飄動，翻捲上翹。龍身作盤踞狀又頗富身段之變化，靈活夭矯而又挺拔有力，剛柔並濟，深具凌空搖曳的層次感。四肢健碩，五爪回勾似鷹，充滿動感。周身鱗片光鮮，鱗次櫛比，雕琢細緻入微。四周滿佈祥雲繚繞，更添騰雲駕霧之象，盡顯威嚴恣意之神態。雕工精湛，海水波紋及龍身皆纖毫畢現，靈活生動，極富韻律感。整器所雕神龍，絲絲入扣，紋理清晰，蒼龍遒勁威猛，磅礴之氣撲面而來，猶如真龍再現，宛然如生，藝術感染力極強，足見乾隆盛世玉作工匠精湛的雕琢技藝。帶木座。
