As a work of art, gold became the main gold-producing area in regions such as Egypt and Nubia due to its rich gold resources. In these civilizations, gold was used as a special material for offerings and decoration to protect the image of the gods. In the Americas, the Chan culture in the Peru area began to use gold as decoration. The Nasca people developed a casting gold technology, using gold and copper to make rose gold. The gold-making technology of the Chim culture reached its peak, producing a large number of gold animal and plant images. In China, the production of gold and silverware in the Tang Dynasty represented the highest level of metal craftsmanship at that time. Processing techniques include gilding, filigree gold, twisted gold, etc.

As a symbol of culture and power, in Europe during the Byzantine Empire period, pure gold jewelry began to incorporate gemstone elements, with themes mostly related to the church and the power of kings.

Gold has become a symbol of currency. Around the 6th century BC, gold began to be used as currency. In the early days, in the Lydia Kingdom, people began to use gold to make coins. And in the Chu state of China, there was also a kind of gold coin called "Ying Yuan".

As an investment, gold is not only a piece of jewelry or currency, but also an important choice for investment. It can maintain a relatively stable value during economic fluctuations, so it is favored by many investors.
