In fact, it is difficult to see the difference between 999 and 9999 gold jewelry, even professional jewelry workers. Although I can't see the difference in color. But where is the price difference between them? I believe many people want to know. Of course, 999 gold ornaments represent 999% gold ornaments and 9999 gold ornaments represent 999% gold ornaments. Therefore, the correct marks of both of them are Jin Jin 999 and Jin Jin 999.9. At the same time, that is to say, the purity of 9999 gold jewelry is only nine ten thousandths higher than that of 999.
