First, recognize the identification of gold content
No longer use the expression "thousands of gold". The National Standardization Administration Committee promulgated and implemented GB 11887-2012 "Provisions and Naming Methods of Precious Metals in Jewelry"No.1,which stipulated gold ornaments with a purity of 999.0‰.
The content of gold and silver jewelry can easily become a gimmick in business promotion to attract consumers to buy "better quality" jewelry. However, whether the purity is "9999" or "99999" actually makes little difference. Therefore, when buying precious metal jewelry such as gold and silver, don't blindly believe in the ultra-high gold content advertised by merchants, just look for "pure gold".
Second, check the texture carefully.
Color: Gold shows different colors due to different kinds and components of impurities. Gold is red and yellow with a fineness of over 95%. Yellow, fineness of about 80%; It is bluish yellow, about 70%; Yellow is slightly gray, about 50%.
Weight: The specific gravity of gold is 19.3g/cm3. When the specific gravity is close to 19.3, the content of pure gold is higher. In the same volume, the weight of silver, copper, tin and lead is much lighter than that of gold, which shows that gold is small and heavy. Gold feels heavy in the palm of your hand, so beware of stupid and light ornaments.
At the same time, pure gold is soft and generally not used for inlaying jewelry. All gold jewelry that emphasizes high-purity inlay generally contains moisture.
Third, be wary of "buying equals earning"
Only jewelry that meets the quality and grade standards has the function of preserving and increasing value, while most jewelry is only suitable for daily life to wear or collect. Some consumers think that buying jewelry is an investment and want to buy it at a low price and sell it at a high price, but they don't know the true value of jewelry before buying it, which makes some unscrupulous merchants take advantage of the consumer's mentality and put up signs of "scarce resources" and "steadily increasing value" to sell fake and shoddy goods to consumers at low prices.
I would like to remind you that regular professional jewelers pay more attention to the quality and reputation of relatively expensive jewelry, so the prices and discounts are relatively stable. When you see jewelry stores selling at low prices, such as "changing seasons, selling old models, 1 discount, 20% discount", please don't hesitate to walk away.
Fourth, correctly understand the meaning of "handling"
We can often see the word "disposal" after the commodity name on the quality certificate such as the appraisal certificate and quality inspection report of jewelry and jade. Consumers who don't know much often understand "treatment" as "cutting, grinding, polishing, inlaying and other treatment methods of jadeite during processing"; Or it is understood as a "defective product" whose price has been lowered. However, a few businesses clearly know the meaning of "handling", but they are vague and push the boat with the tide in the face of consumers' inquiries, misinterpreting the word "handling" and misleading consumers.
According to the national standard issued by 1996 (implemented on 1 May, 19971day), jadeite (treated) refers to jadeite treated by glue injection or artificial coloring (dyeing) after removing impurities by pickling, which is called jadeite B, C or B+C in jewelry industry. Since the national standard 1997, the names of jadeite A, B, C and B+C have been removed from the identification label of jadeite commodities, and they are summarized as jadeite B, C and B+C, and replaced by "jade (treatment)". To put it bluntly, "processing" means that this jade is not pure natural jade.
Five, "dazzling" gold inlaid with jade
The finely carved jade is inlaid with dazzling gold. "Gold inlaid jade" is a very popular ornament in the market at present, and many consumers are moved by it. Although it seems that there are jade and gold, the actual cost of most "gold inlaid jade" ornaments on the market is not high. "Gold inlay" is made of very thin gold foil, and its weight is mostly less than 0.1g. And the quality of jade is also low. This kind of jewelry is very profitable for consumers even if it is given a very low discount. Please pay attention.
Sixth, there are many hidden dangers in online shopping for gold, silver and jewelry.
1, there are differences between the goods and the objects in the video and photos. Some jewelry looks bigger, but it is far from the real thing; Some videos and pictures are beautiful in color and tone, but they are actually black and yellow; Some jewels have spots or cracks, but they can't be seen in videos or photos.
2. Sales skills and means. When consumers meet their favorite goods and order from merchants, they will often get a reply that the goods are "out of stock", and then the merchants will immediately recommend other styles to consumers and spare no effort to recommend them until the transaction is completed. Among them, the product that consumers like is likely to be a gimmick from beginning to end-there is no such thing at all, but the merchants know the needs of consumers and then make targeted sales accordingly. At this time, the products recommended by the merchants to consumers will make consumers think that this product and their favorite products belong to the same grade, so whether the two products really belong to the same grade is only known by the merchants themselves.
3. Exaggerated words and expressions. Many anchors and agents in online shopping live broadcast are completely unaware of it. They will intentionally or unintentionally promote handicrafts to the collection category in the written expression, or make fake certificates of gold and silver jewelry, and also forge the inquiry website and telephone number on the certificate to form an industrial chain, plus hype language for publicity.
Finally, I want to remind you of the following points:
1. When buying gold and silver jewelry, be sure to weigh it again on the calibrated and calibrated balance to confirm that the quality (weight) information has been indicated on the relevant bills.
It is the most cost-effective to buy gold ornaments priced by gram, which is the real equivalent exchange.
3. Gold and silver jewelry should be purchased in regular shopping malls, specialty stores and counters; Don't buy jewelry and jade in tourist attractions.
4. After the transaction is completed, the merchant must issue a formal invoice and confirm that the billing information is consistent with the purchase information. It is best to list key information such as quality and material in detail.
