Long-term wear is easy to contact with body fluids and oils secreted by human skin, which will make chalcedony brighter and brighter. At the same time, pure natural chalcedony contains many minerals and trace elements beneficial to human body. Under long-term close-fitting wear, these substances will penetrate into the body through the human skin, thus increasing the body function of the human body, promoting the digestive function between the stomach and intestines, and can play a role in strengthening the body of the wearer. In addition, long-term wearing can also increase the spirituality of chalcedony. From the perspective of geomantic omen, it can increase the affinity with chalcedony, and it can also play the role of exorcising evil spirits and eliminating disasters, keeping peace and avoiding some negative energy violations.
