Although there are no characters on this jade, the patterns on it can roughly determine the date of its creation.
The reason for this determination is because the carvings on the cup have selected the patterns of gold and silver wares from that era, and the approximate time of the cup can be easily determined through these patterns.
The development of gold and silver wares in the Tang Dynasty can be divided into three stages: The first stage was from Emperor Gaozu of Tang to the early stage of Emperor Xuanzong of Tang, during which the gold and silver wares developed rapidly and were heavily influenced by foreign cultures.
The main types of utensils included high-foot cups, cups with handles, and multi-curved long cups with more than five curves. Folded belly bowls and clam-shaped boxes were also common, as well as jugs and bottles.
