The fire burning method puts the jewelry in the fire to barbecue, and removes it when the jewelry is red. After cooling, the pure gold jewelry is still new, and the surface of the K gold jewelry shows a gray oxidation layer. The lower the purity, the darker the color. 2. Select a black test goldstone with delicate texture, use gold films with different gold content to draw traces on the test stone, make comparison standards, and then scratch the jewelry you want to test on the same test gold stone, drip the concentrated nitric acid to remove the miscellaneous objects. The traces left on the goldstone are the gold content of the accessories. In contrast to the standard, find out the same color as the trace, which is the accurate amount of the determined jewelry. 3. The nitric acid with a concentration of 70 % is dripped on the jewelry, and the original is true. It is not a real golden jewelry that occurs in chemical reactions.

The feel of K gold jewelry is not as heavy as pure gold jewelry. In addition, both pure gold and K gold jewelry have a printing sign. Printing on gold jewelry is used "gold" and "KG" English letters represent the texture. When indicating the gold content, the word "99" or "24K" indicates that it is pure gold jewelry. The K gold jewelry is marked with the corresponding K number, such as the K gold jewelry marked "18K". %. In addition, the jewelry also marks the printing of the origin of different manufacturers.

There are many types of jewelry that is easy to confuse with gold jewelry, some are gold -plated jewelry, some are gold jewelry, some are copper jewelry, and some are copper alloy besiege. The following briefly explain: Gold -plated jewelry is plated on the surface of other metal jewelry on the surface of the metal jewelry. The color is similar to the real gold jewelry. The golden light is bright, and it is difficult to confirm the new time. However, the gold -plated jewelry feels lightly, the texture is hard, the teeth are bitter, and it is easy to fade with a long time. Some gold -plated gold -plated jewelry, the color is either red or white, or flowers. Color gold jewelry refers to 24K or 22K gold foil on other metal breads, such as the KD of K gold foil is too low, and its softness is poor. The appearance of the golden jewelry is similar to the real gold jewelry. The golden light is sparkling and it is not easy to fade, making it difficult to argue. However, if you carefully observe the depression, angle, back, etc. of the jewelry, you can find that the gold foil is uneven and there is a phenomenon of tilting edges. If there are broken joints on the jewelry, the cross section of the metal material can be seen from the outside. In addition, the feel of the gold jewelry is also lighter, the texture is harder than the pure gold jewelry, the teeth are bitter, and it is not easy to bend.

Copper alloy jewelry (copper tin alloy), white color, hard and light quality, long -term coloring, will make the skin darker. Whether it is gold -plated jewelry, gold jewelry, copper jewelry, and Asian gold jewelry, it generally does not have a printing sign similar to gold jewelry. Or it is different from gold jewelry. If some jewelry is engraved with the English letters "GK", it means "gold plating". Or the signature traces are blurred and crooked. Consumers should identify whether there are printing, printing whether the printing is in compliance with the above provisions, and whether the printing is clear, etc. to determine the authenticity of gold jewelry.
wholesale kendra scott jewelry When buying gold jewelry, you can identify from the following aspects. Different color: Gold 70 % of its jewelry is yellow in the middle, 80 % of Jin is yellow, and 90 % of gold is yellow in yellow, and 10 % of gold is red. 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. Extremely important: The proportion of gold is 19.3 grams/cubic centimeter. The color is more related to the proportion. When the proportion is close to 19.3, the higher the pure gold. At 18.5, the gold contains 95%, and the gold contains 90%at 17.8, and so on. As long as the proportion is measured, the color of the jewelry can be seen. But most people can have a sense of precipitation. Seeing the rhyme: The high -quality jewelry will have a dull sound on the cement floor, there is no 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. Test soft and hard: the higher the color of the gold jewelry, the softer, the more elasticity. The real gold will have light marks with teeth or needle. Low -colored and fake are the opposite.
