When buying precious jewelry, especially when buying diamond jewelry, the biggest confusion for consumers is the identification of the value of the goods. The primary reason for this is that the price of such products is intuitive and comparable, and consumers cannot Another reason for the value of such goods is that there are more value evaluation factors for such goods. There are four direct evaluation parameters for diamond jewelry (the 4C is often said), and the indirect parameters will be more. Then, what is the quality of a certain diamond jewelry that consumers are exposed to, and how to ensure the quality is a problem that must be clear in the consumption process.
With the continuous improvement of the consumption level of our people, the demand for quality inspection of such products and the certification materials must be met, so most of the high-end jewellery, especially the diamond ornaments, are attached. Product quality inspection certificate. However, we found in the market that the identification certificate of the diamond jewelry has different types of identification certificates used by different brands in different brands. Since consumers do not understand the relevant knowledge of the certificate, they often have many doubts when purchasing. Now, take the product identification certificate of the famous diamond jewelry brand Ryan Diamond Jewelry as an example to introduce the relevant contents of the certificate.
First of all, we must look at inspection agencies. Some well-known brands such as Ryan are certified by the national jewel gem quality supervision and testing center of the national inspection unit, and they are consistently used nationwide because of the quality supervision and inspection of national jewellery and jade. The center is a national quality jewellery and jade professional quality inspection agency authorized by the State Bureau of Quality and Technical Supervision. It is the authoritative organization for domestic jewellery and jade detection.
The second is to look at the test content, including jewelry name, diamond quality level, shape, color, clarity, total quality and other items. According to the staff of Ryan's famous shop, the large-scale institutions like the National Inspection Center are very strict, and Ryan is also an important part of the internal quality control.
Again, check the physical product against the physical picture on the certificate. There are physical pictures taken on the brand certificates such as Ryan Diamond Shop, because the inspection certificate of the diamond jewelry is one-to-one corresponding to the product, and it is the unique identification document of each product. Therefore, the physical product and the product The comparison will also help consumers to buy with confidence.
In addition, the certification of the diamond jewelry product is also authoritative or not. It is also indicated in the certification and accreditation department indicated by the certificate. For example, we have seen the sign of the metrological certification of the State Bureau of Quality and Technical Supervision (MA type pattern) on the calibration certificate of Ryan diamond products. ), the National Quality and Technical Supervision Bureau product quality supervision and inspection agency authorized certification mark (A type pattern), China Experimental Center Accreditation Committee Laboratory Accreditation Committee laboratory letter mark. This also proves to a large extent the authority of the identification certificate used by Ryan diamond shop and other merchants and the guarantee of product quality.
The small certificate hides a wealth of knowledge, consumers can start with the certificate, through careful selection, you can choose the product that suits your requirements.
