Summary:A method of measuring a concentration of nitrogen in diamond includes a first step, a second step, and a third step. In the first step, diamond is arranged in the inside of an integrating sphere. In the second step, visible light is emitted to the inside of the integrating sphere and the visible light that is reflected by an inner surface of the integrating sphere and passes through or is reflected by diamond arranged in the inside of the integrating sphere is received. In the third step, the concentration of nitrogen in diamond is calculated based on data on received visible light and a mass of diamond.
