A method for manufacturing nephrite into high density micro-powder is provided to enable nephrite to deliver its efficacy such as activation of cell function, blood circulation, and body metabolism to human body more effectively. A method for manufacturing nephrite into high density micro-powder includes the steps of: crushing raw stone of nephrite in a jaw crusher firstly; putting and crushing the crushed nephrite in a cone crusher secondly; grinding the secondly crushed nephrite into nephrite particles in a roll crusher; putting the ground nephrite particles in jade purified water and stirring them; drying the stirred nephrite to semi-dried state in a drying room; and pulverizing the semi-dried nephrite into high density micro-powder in a silicon roll crusher.
