How to identify true and false jewelry?
How to identify the authenticity of jewelry 1, see logo.
According to the national regulations, jewelry sold in the market must have corresponding identification, and the identification of jewelry includes the material and content of jewelry. Take silver products as an example. Silver ornaments are usually marked with S925 or S990. S stands for silver, which is the material of jewelry, and 925 stands for metal content.
Step 2 read the certificate
Jewelry sold in the market will have the certificate of a professional jewelry appraisal institution, which can be used as a certificate to distinguish between true and false. However, some unscrupulous merchants forged jewelry appraisal certificates. When buying jewelry, you should pay attention to distinguish between true and false jewelry certificates. Jewelry appraisal certificate has pictures and information of products.
Step 3 look at the specific gravity
Natural gems and rare metals have a large proportion, high density and a certain sense of weight, which can be distinguished by testing the proportion of jewelry. When measuring the same volume of jewelry, the real jewelry has a large proportion, while the fake jewelry has no sense of weight and a small proportion.
4. Look at this color
The color of jewelry greatly affects the market value and quality of jewelry. There is a great difference in color between true and false jewelry. Natural gemstones are pure and gorgeous in color, with uneven color distribution and natural color transition, while fake gemstones are dull in color, and some fake gemstones will also show glass luster.
Step 5 look at the clarity
The purity of jewelry usually refers to the purity and transparency of gemstones. You can observe the characteristics of jewelry with a high magnification magnifying glass. Naturally occurring gems or metals will contain some cracks and flaws. Synthetic metals and gems are more perfect, with fewer defects, rough texture and dull luster.
