How to distinguish real gold from fake gold in a simple way?

The following methods can be roughly judged:

1) Look at the color: **The higher the purity of the jewelry, the darker the color. In the absence of a gold medal, the general color can be determined according to the following colors:

The color of dark red yellow is above 95, light red yellow is 90--95, light yellow is 80--85, blue-yellow is 65-70, the color blue with white light is only 50--60, and the yellowish and white is less than 50.

2) Weight: The specific gravity of ** is 19 32, which is heavier than silver, copper, lead, zinc, aluminum and other metals. **Jewelry should have a sense of sinking in the hand, and fake gold jewelry feels light. This method does not apply to ** jewelry inlaid with gemstones.

3) Look at the hardness: pure gold is soft, low hardness, shallow marks can be scratched with nails, teeth can leave tooth marks, ** jewelry with high fineness is softer than low fineness, the more copper content, the harder it is, the bending method can also test the hardness, pure gold is soft, easy to bend, the lower the purity, the less easy to bend.

4) Listen to the sound: real gold with a fineness of more than 99 is thrown on the hard ground, which will make a horn sound, with no rhyme and no elasticity. Fake or low-color** sound is brittle and no dullness, generally makes a "dangdang" sound, and the sound has an aftersound, and beats violently after landing.

5) Burn with fire: burn the jewelry to be identified with fire (do not melt and deform the jewelry), observe the color change after cooling, if the surface is still the original ** color is pure gold; If the color is darkened or darkened to varying degrees, it is not pure gold. Generally, the lower the fineness, the stronger the color, and all of them turn black, indicating that it is fake gold jewelry.

6) Look at the mark: domestic ** jewelry are purified and prepared according to international standards, and marked with a killing mark, such as "24k" marked with "foot red" or "pure gold"; 18K gold, marked with the word "18k", the fineness is lower than LOK, according to the regulations, you can't play K gold stamp. At present, criminals in the society often use fake brands, imitation stamps, and use rare gold, sub-gold, and even brass to pass off as real gold, so the identification of ** jewelry should be determined according to the sample for comprehensive judgment to determine the authenticity and fineness.

Personally, the best and easiest way is to go to the specialty store to get identified. You just say you want to change the product, and they will give you a free appraisal first. Then you think about it, you have to pay depreciation for changing the product, and think about it or not. o(∩_o~

2. Look at the color method**The higher the purity of the jewelry, the darker the color will be. We can determine the general color of ** according to the following colors: the purity of the color is dark red yellow above 95, the purity of light red yellow is 90--95, the purity of light yellow is 80--85, the purity of blue-yellow is 65-70, the purity of white light is only 50-60, and the purity of light yellow and white is less than 50.

Usually the so-called seven green, eight yellow, nine red can be used as a reference for identifying the true and false. The fastest way to identify the authenticity is the weighing method and the color method introduced above, of course, we have many other fast ways to identify the authenticity of the **, it is recommended to understand more, compare more. 3. Magnet test This is a simple test, but it is not a sufficient proof to prove whether it is real gold.

You can find a strong magnet to do the test. **Not a magnetic-containing metal, if your product is attracted to a magnet, that's enough proof that this product is not**. But just because your product doesn't react to magnets doesn't mean it is, because there are many more non-magnetic metals.
