The formation of nephrite jade is related to high-pressure, low-temperature metamorphic processes, which act on magnesium-rich raw rocks and minerals">rocks. Nephrite deposits are usually associated with metamorphic raw rocks and minerals">rocks such as schists and serpentines. Due to its remarkable physical properties, nephrite jade has been used by humans for thousands of years. Its hardness and resistance to wear have made it a preferred raw material for the manufacture of tools, weapons and art objects.
