5 thoughts on “What are the best ways to distinguish the authenticity of gold jewelry?”

1: Hardness. The hardness of gold jewelry is relatively soft, and it is easy to bend. The lower the purity, the harder it is to bend. So if it is hard gold jewelry, it is likely to be adulterated 2: weight. Weigh the weight of gold jewelry in your hand to see if the weight and volume of jewelry are commensurate. If you are large and light, it is likely to be adulterated. If it has a slight sinking feeling, this is real gold jewelry 3: sound. If gold jewelry is thrown on a hard ground, if it makes a popping sound, there is no rhyme and no elasticity, it means that the fineness of real gold is more than 99%, while the fake or low fineness will generally make a Dangdang sound, and the sound has aftersounds, which will jump violently after landing.
1. Look at the color: according to the different luster and color of gold, you can roughly distinguish pure gold, K gold, real gold and fake gold. The old saying "seven green and eight yellow, nine five red, yellow and white with gray half gold" passed down from pawnshops describes the purity of gold. If the color is green and white, the purity is not high, and if the color is red and yellow, the purity is high
2. Look at the mark: according to the regulations, domestic gold jewelry should be marked with a mark of killing. If 24K is marked, it means that the purity is above 99.6%; if 18K is marked, it means that the purity is above 75%
3. See hardness: gold with high fineness can leave traces when it is scratched with pins or nails. More than 97% of the gold jewelry with good quality will appear wrinkles at the bend after being bent two or three times, also known as fish scale lines; About 95% of the gold jewelry with good quality feels hard when it is bent, and the fish scale pattern is not obvious; Gold jewelry of about 90% quality is very hard when folded, without fish scale lines; Gold jewelry with more impurities will break after bending for two or three times; If it is made of raw gold, it will break when it is bent, and the section will have obvious sand grains
4. Listen to the sound: when real gold with a fineness of more than 99% is thrown on the hard ground, it will make a popping sound without rhyme or elasticity. The false or low-quality gold sound is crisp without dullness. It usually makes a "Dangdang" sound, and there are aftersounds. It beats violently after landing
5. Weight: the specific gravity of gold is 19.3g/cm3, and the fineness is closely related to the specific gravity. When the specific gravity is close to 19.3, the higher the pure gold content is. Weigh its weight by hand to see whether it is commensurate with the volume. Large and light shapes may be adulterated. But generally, if you weigh it in your hand, you can feel that it is genuine gold jewelry if you have a slight sinking feeling. It can be seen that the gold is small and heavy. We should be alert to bulky and light ornaments and carefully distinguish whether they are fake or semi fake
6. Try soft and hard: the higher the fineness of gold jewelry, the softer it is, and the less elastic it is. Real gold will have light marks when it is bitten by teeth or scratched by needles, and there will be no broken lines when it is folded by hand. The color is low and the steel is hard; The heavy mixer is elastic, brittle and easy to break. Pure gold is softer, so it is generally not used to make inlaid jewelry. Therefore, any inlaid gold jewelry claiming to be 24K must be deceitful
7. Scraping porcelain plate method: find an unglazed porcelain plate. If you don't have one, you can go to a home improvement shop and buy a piece of porcelain. Scrape the porcelain plate with gold. If there are black scratches on the porcelain plate, your gold is not real gold. If the scratches are gold, it is real gold. This method can expose the fake gold, but your gold may be scratched
8. Nitric acid test method: put the gold ware into a small stainless steel container, drop a drop of nitric acid on the gold ware, and observe the reaction. If the acid drops appear green, the gold ware is either made of common metal or plated with gold. If it is gold, it is gold-plated copper. If it is milk colored, it is gold and silver plated. If there is no response, then this gold is real. Nitric acid test is a good way to distinguish the authenticity of gold. However, since nitric acid is not easy to obtain and it is dangerous to operate at home, it is recommended that you hand it over to jewelers
the above are the tips and methods that Xiaobian shared with you to distinguish the authenticity of gold jewelry. I hope it will be helpful to you.

I think the most practical and direct way to distinguish the authenticity of gold is to take it to the store for testing.
I found gold jewelry on the road. Keep these tips in mind and immediately distinguish the true from the false. I wish I could learn them early. P>
