Abstract Because of raw materials and technologies, synthetic diamond crystal contain a small quantity of impurity elements, and iron and nickel are main impurities in powder technology. Different quantities of impurity elements have different influences on characters of diamond. This test depicts the measurement of percents of nickel and iron in different grades' synthetic diamonds. Comparative analysis influences of impurity quantities for diamond's characters.
