With the improvement of everyone's living standards, gold jewelry has gradually entered the families of ordinary people. However, for many people, how to distinguish the authenticity of gold and falseness is not well understood. For this, I will share it for everyone here. How do you distinguish the authenticity of gold.

. Visual inspection
1. The official sign of checking gold. Generally, 999 or 990, or 10K, 18K, 22K, 24K. It is not considered lower than 10K, because the content of gold is too low. If you observe with a magnifying glass, you will see more carefully.
2, ancient gold jewelry will not have obvious official purity logos.
3, of course, there will also be official signs of counterfeit gold jewelry, so further inspections need to be performed.
4, find obvious discoloration. Check the wear area of the golden surface, which is usually on the edge of the golden products to check the color change there. If the golden color disappears and becomes another color, then this product is just a gold -plated.
. The bromine chemistry test
1. Put the golden product into the alcohol solution for a small meeting.
2. Put a piece of filter paper into the sperm solution.
3. At this time, the filter paper becomes gray -purple.
4, drops 4 drops of bromo -A reagent to the filter paper, if the filter paper becomes white, then this gold product is real gold.
The test time takes 20 minutes.
. Magnetic test
This is a simple test, but it is not a sufficient proof to prove whether it is true gold. You can find a powerful magnet for testing.
Gold is not a magnetic metal. If your product is attracted by magnets, it is enough to prove that this product is not gold. But you can't prove that it is gold because your product does not respond to magnets, because there are many non -magnetic metals.
. The density test only has a very small metal density exceeding gold. The density of pure 24k gold is about 19.3 grams/ml, which is much higher than other metals. The density test method is enough to prove that your product is gold. The higher the density, the higher the purity of gold. Make sure your product has no additional gem.
1. If you do not have equipment in this area, jewelry shops can usually do density testing for you.
2, you can put your golden products in the container full of water, and then test the volume of overflowing water, and then remove the weight of your gold product, which is the density of your gold product. Keep in mind that different gold purity has different grams/ml ratio: 14k- 12.9 ~ 14.6 grams/ml 18k gold-15.2 to 15.9 grams/ml 18k platinum-14.7 ~ 16.9 grams/ml 22k-17.7%to 17.8 grams to 17.8 grams /Ml.
. Bite test
everyone has watched movies, and the mininger bite gold to test it. I also saw that when the Olympic athletes won the gold medal, they would bite their "gold" medal. How simple this test is.
1, bite gently.
2. Check your bite marks. The deeper the bite marks, the higher the purity of the gold.
Actually, this is a not recommended test, which will damage your teeth. What's more, the lead will be given to the gold, and the lead is softer.
. The test method of ceramic scratch
1. Using unlawish ceramics. If you don't have this, you can buy it from a ceramic shop.
2. Cover your gold products with ceramics. If it is a black scratch, it means that your product is not gold. If it is a golden scratch, it proves that your product is gold.
Igly, if you want to buy gold jewelry, it is best to go to a well -known brand store to buy it. Do not blindly pursue low -cost discount gold.

If there is no gold medal, you can determine the general color according to the following color (based on green gold. The so-called green gold contains only silver ingredients in gold); dark red yellow color is more than 95%, light red yellow 90-95% The pale yellow is 80-85%, the cyan is 65-70%, the color blue with white light is only 50-60%, and the slightly yellow and white are less than 50%. Generally, Qiqing, Eight Huang, and Jiu Chi can be used as a reference.nSecond, fire jewelry, observe the color changes after cooling. If it is pure gold, the surface is still golden yellow after burning. If the color is dark, it is not pure gold. However, pay attention to observation when burning, do not burn jewelry to deform.nThird, listen to the sound. Putting pure gold jewelry on the ground will make a click. The fake or bad gold falls on the ground, and it will make a dwelling sound, and it will be beating after landing.nFourth, bite gently with your teeth. In gold jewelry, the pure gold jewelry texture is soft, the teeth are bite, and it is easy to bend. The color is golden, pure, soft, feels heavy, and has a heavy feelingnMore 2nBleak
