project halo jewelry wholesale I have never heard of Diaobu, but I have only heard of Zhou Dafu. How do I judge whether the gold ring is true? Gold ring authentic and false simple identification method is exposed -
. Disted materials
The gold ring has a single material and a variety of materials. A single material is platinum and gold. A variety of materials are made of platinum, gold, and inlaid. First of all, you must distinguish what kind of material you need, and then make the next judgment.
. Seeing color
The real gold ring is warm yellow, harmonious in color, delicate surface, bright and bright colors. Excessive redness may be pseudo -gold. If the color is too shallow, it may be a mixed alloy such as silver and aluminum. The darker the color, the more valuable, and the dark yellow yellow is the purest. How can you see that the gold ring is true or false. It is easy to leave traces with hard objects. Throwing "板" on the table, the fake floor sound is more sharp and higher than the real jump. It really does not change color when it comes to fire, and fake will become black -purple and bright.
. Seeing workmanship
The surface of the gold ring is uniform, smooth and smooth, without defects, mottled, scars, sand grains and other defects. Welding and mouth should be smooth and thick. The pattern is clear and not heavy. The lines on both sides are neat, parallel, and toothless. The pattern combination design workmanship coordinated, the ring of the ring is smooth and smooth, without burrs. The above is the simplest and intuitive gold ring authentic and false identification method.
5. See weight
The weight of the weight with the size of the volume, the shape is large but lighter. But generally in your hands, if you have slightly sinking, you can perceive the real gold jewelry, and the real gold rings have a weight with your hands. It's really heavier, and the fake is lighter. The proportion of gold is 19.3g/cm3, which has a large relationship with the proportion. When the proportion is close to 19.3, the higher the pure gold. You should be vigilant for the stupid and light jewelry, and carefully discern whether for fakes or semi -fakes.
6. Seeing the mark
The domestic gold jewelry is made from being purified in accordance with international standards, and will be used on it. For example Those who have a color less than 18K will not be able to call the K -printed number according to regulations.
7. Test soft hard
The higher the color of the gold ring, the softer, the more elastic. Low -colored steel is hard; those with heavy mixes are elastic, crispy and easy to break. The pure gold is soft, and it is generally not used to make embedded jewelry. Therefore, all inlaid gold jewelry claims to be 24K and there must be fraud.
eight, seeing the rhyme
The high -colored jewelry, throwing on the cement floor, there will be dull tabs, sound without rhyme, no strength, commonly known as dead sound. On the contrary, the low -collision gold jewelry is thrown on the cement floor with rhymes and sharp sounds, and a slight jump.
. Certificate query
gold jewelry purchased in regular merchants will have its own number. You can log in to NGTC for query. Genuine products will have their own information. NGTC is a country authorized by the State Administration of Quality Supervision and Inspection and Quarantine according to law. Class jewelry and jade professional quality inspection agencies, this is the most direct identification method.
. Chemical reagent method
This is a very professional chemical identification method, but it is still not used as a last resort.
It 45%nitric acid test: gold and platinum have no change, silver becomes black, and copper is green foam. This is because the chemical properties of gold and gold are stable, and they will not be oxidized in any state, and they are also very stable in water, air, hydrogen sulfide or salt, and alkaline environment. Gold is soluble in any kind of single acid, which is only dissolved in the king water (the volume of the volume of the hydrochloric acid and nitric acid is based on a mixture of 3 to 1). Use this method to identify, and the gold ring fled.
It gold ring identification of other methods —
This Burning identification method: Burning real gold jewelry with fire can durable and unchanged. Will lose.
This identification method: Drives a hard needle tip on the real gold surface, which will produce obvious traces, otherwise fake will be more vague.
This bending method: Broken the gold ring with your hands. If it is a soft texture, it is easy to bend and not easy to break.
If Note —
The gold rings of the gold ring or above will cause damage to the ring, so you have to try it easily.
