The jade carvings of theQing Dynasty inherited the system of the Ming Dynasty, and most of the utensils were inherited. This bottle is an important display jade in theQing Dynasty. Its shape is derived from the jade carvings of the Ming Dynasty. The square-shaped jade vases are uniform in shape, well-regulated and powerful, and are particularly rare and unique in shape. Made of the above-mentioned Hetian jade, the jade is warm and delicate, shiny and smooth, with thick patina, and the whole vessel is made of two bottles of the same size, which are closely nestled together, standing side by side, and integrated into one. The cover button adopts "relief carving" and "openwork carving" techniques to carve chi dragons. The dragon's body is graceful, winding and entrenched, vivid and natural. The utensil is square in shape, with double chilongs in relief on the left and right, and a ring on the lower body. The body is embossed with "jomon", "bat", "jade chime" and "hanging tassels". 清代玉雕承接明代之製，器型多有傳承，而得益於清代西域廣闊的領土逐漸平定，使得昆崙玉路暢通，大量高質量的玉材源源不斷的流入中原，也促使了清代玉雕工藝和作品質量的進步。此瓶清代重要之陳設玉器，其形制來源於明代玉雕雙聯瓶，在原作基礎上，充分應用質量上乘、體型碩大的原料加以創新，將整塊和田白玉圓雕掏膛而成，左右各雕以方狀玉瓶，形制如一，規矩有力，形制特殊罕見，獨一無二，往往是皇家貴族重要陳設器，實為千金不易，可遇不可求的珍稀之品。以上等和田玉製成，玉質溫潤細膩，瑩潤光潔，包漿肥厚，整器作大小相同兩瓶緊密相偎，並肩直立，合而一體。蓋鈕採用“浮雕”“鏤雕”技法，雕飾螭龍，龍身婉轉，蜿蜒盤踞，生動自然。器呈四方型，左右浮雕雙螭龍，下身帶有銜環。器身浮雕“繩紋”“蝙蝠”“玉磬”“掛穗”，整體層次井然，紋飾古雅，形制獨特，工藝精湛，線條挺拔硬朗，頗具裝飾意趣，紋飾整體協調一致，寓意美好，細部刻畫游刃有餘，足顯工匠高超技藝，展現典型的清宮禦製風格。
