Cambodian gold purity consideration
First of all, it is very important to understand the purity standards of Cambodian gold.Generally speaking, the international standards are expressed by thousands of points.24K represents the highest purity, that is, more than 99.9%is truly pure gold; 18K means more than 75%of gold; 14K contains more than 58.5%, and so on.

Method of identification
1. Visual inspection method: By observing color, luster, and appearance, you can initially determine whether it is the real gold.The real 24K yellow is brighter and uniform, and the mixed alloy can make the color uneven.
2. Magnetic test: Because the real gold is non -magnetic material, it will not be adsorbed when using magnet attraction; if it is adsorbed, it may be mixed with other synthetic substances.
3. Density test: Use the specific scale of the mercury sealing device and calculate the density value to determine whether it meets the standard density value.
4. Chemical reagent test: The use of nitric acid for chemical test can quickly distinguish whether it contains other synthetic substances.
