Because thousands of gold is different according to the purity, the color may be different, and the color may be different.
The gold content is not less than 999, which is called thousands of gold. The mark is thousands of gold, 999 gold, GOLD999 or G999. The mark of gold jewelry includes manufacturers' code, materials and purity, such as: X Gold 990, XAU990, X -foot gold, etc.
Among them, the letters X are the manufacturer code. When making jewelry with different materials or different purifications, materials and purity should be represented separately. When the jewelry cannot be printed due to too thin or too small, it should be attached to the logo containing the mark content.

The choice method
thousands of gold is its unique golden brown luster (low color exception), pure The golden light will flashed with dazzling light under the strong light, which is not available in other metals, including copper inside.
The thousand -footed gold with a high color, no rhyme and elasticity when the sound is thrown in the ground, and the sound quality of the low -footed gold is slightly brighter, and when the copper product is thrown on the ground, the sound is loud. Therefore, according to the sound of the knocks, we can help us distinguish between common metals and gold.
Thousand -footed gold has the characteristics of good ductility and small hardness. Pure gold is folded and soft, and the bronze strips are laborious. Or use large head needles (nails are also fine). If the force is not large and the traces are obviously golden, the copper is slightly stronger and the traces are slightly worse.
This soft and hard only applicable to rings, gold silk and the like, which is more difficult for gold bars, gold coins, BRICS and the like. The authenticity of the first judgment of gold is also effective, but it is necessary to use different orientation of the inspection objects. If the color of several grinding roads is obviously different, adulteration is undoubtedly mixed.
