The artistic value of Changhua chicken-blood stone lies in its adaptability. It can be made into ornaments of various sizes and forms, such as pendants, rings, bracelets, necklaces, waist tags and other accessories.

It is not only a mineral specimen that records geological upheaval, but also a cultural relic that reflects the productivity of different eras, living conditions and folk customs.

The cultural connotation of the stone also lies in its integration with Chinese customs, wishing people well and social morality. For example, red, favored by Chinese people, represents joy, victory, success, luck and fortune.

It has become a cultural icon to deepen bilateral friendship in diplomatic activities. In 1972, Chinese premier Zhou Enlai gave the then Japanese prime minister Kakuei Tanaka and Japanese foreign minister Masayoshi Ohira Changhua chicken-blood stones as State gifts when the two countries established diplomatic relations.

In 1986, a seal of Changhua stone was presented to then US president Ronald Reagan. In 2016, the Changhua stone sculpture "Haliaeetus Albicilla Duda Portrait Seal" was presented to Polish President Andrzej Duda.
