The agate cup inlaid with gold in the Tang Dynasty is carved from red, brown and white agate with distinct layers. One end is carved into a cup mouth, and there are two convex strings outside the edge of the cup mouth, so the cup body is smooth and smooth. The other end is carved into a vivid and lovely animal head, staring round and looking straight ahead. Two long horns, strong and powerful. The animal's mouth is irregular and oblate, with the widest inner diameter 1 cm and the widest outer diameter1.4cm.. There is a golden cap outside the spout, and the golden cannula behind the golden cap blocks the spout. The cannula is slender and hollow, and the golden cap is carved into a beast's mouth closely connected with the spout, so that the liquid in the cup will not flow out, and at the same time, it adds a lot of color to the agate.

The material of the agate cup with gold head in Tang Dynasty should come from abroad. According to the "Old Tang Shu Gao Zong", in the fifth year of Yonghui (654), "In December, Japan presented amber and agate. Amber is as big as a bucket and agate is as big as five buckets. " In the Biography of Old Tang Persia, an envoy once offered an agate bed. "Old Tang Biography" contains: "There are many treasures of gold and silver on the ground, including luminous jade, bright moon beads, scary chicken rhinoceros, big shells, car canals, agates, Kong Cui, corals and amber. There are more exotic things in the Western Region than in other countries." It can be seen that agate tributes mostly come from Persia, Fu, Japan and other countries.

The shape of the agate cup inlaid with gold in the Tang Dynasty is similar to that of the western "Laitong". "Laitong" originated in the west, and this artifact appeared in Crete, Greece in 1500 BC. The Greeks called it "rhyton", just like a funnel, which can be used to inject wine. At that time, people thought that Laitong Horn Cup was a sacred object, and injecting wine could prevent poisoning. If it is lifted, it will be a tribute to Dionysus. After it spread to Asia, Letong was widely popular in Mesopotamia, amur river and even China. The origin and age of the animal head agate cup are still under discussion. Some people think it is an imitation of the Tang Dynasty in the eighth century, while others think it is an imported product, dating back to the seventh century.
