Wearing these natural gems that have grown for a long time and survived the vicissitudes of life has the power to go against the sky, which can exorcise evil spirits, eliminate disasters and bring good luck to yourself. This is an auspicious thing.

In addition, different sects regard jewelry as the holy spirit, and gold represents the dignity of the gods in people's hearts. For example, in Notre Dame de Paris, a Catholic church in the west, the jade box where the priest put the Bible and the silver plate containing holy water are all inlaid with many gems of different colors. Oriental Buddhism and Taoism will gild the Buddha statues in temples, representing the majesty and dignity of the gods.
