(2) Type weight: The proportion of gold is 19.32, which is more important than metal such as silver, copper, lead, zinc, aluminum. The volume of gold is more than 40%heavier than the silver, 1.2 times heavier than copper, and 6.1 times heavier than aluminum. The gold jewelry should have a feeling of sinking in the hand, and the fake gold jewelry feels lightly. This method is not suitable for gold jewelry inlaid.

(5) Burning with fire: The jewelry will be burned red (do not melt the jewelry) with fire (do not melt the jewelry), and observe the color change after cooling. If the surface is still the original golden color is pure gold; Dark or different degrees of darkness is not pure gold. Generally, the lower the color, the stronger the color, and the darkens are all, indicating that it is a fake gold jewelry.
(6) Seeing the mark: Domestic gold jewelry is all customized according to international standards, and the killing records, such as "24K" indicate "foot red" or "foot gold"; 18K gold, 18K gold, The word "18K" is marked, and those who have a lower color are lower than LOK.
