Nowadays, the gold jewellery market is advertised as “Wanquan Goldâ€, “Thousands of Pure Goldâ€, “Pure Gold†and “K Gold†products. It is also very eye-catching. How to ensure the true price of gold jewellery has become one of the most concerned issues.
With this question, Xiaobian visits the professionals to answer your questions in detail.
You must know the gold
Gold is not red
As the saying goes, "gold has no foot red", that is to say, there is no 100% pure gold. In China's industry standard, the highest purity gold is thousands of gold, followed by gold.
Thousands of gold

You should know the gold
3D hard gold is a craft, not a gold content
Also called 3D hard thousand gold. It is a new product that has only come out in recent years. It does not refer to gold content, but refers to an improved invention of a gold electroforming process for the manufacture of hollow thousand gold products with complex shapes, fineness, high hardness and strong abrasion resistance.
Characteristics
The hardness of 1.3D thousand-foot hard gold is 4 times higher than that of traditional gold, which is very close to the hardness of 18K gold. It effectively overcomes the shortcomings of low hardness, easy wear and difficult to maintain fine patterns.
2.3D hard thousand gold is mostly chic and looks bigger, that is, the same size of jewelry, 3D hard thousand gold is much lighter than ordinary thousand gold, but its labor costs are very high.
Wanjinjin has no defined standard
The total amount of gold, that is, four 9 gold, in general, the purity of spot gold purchased by the Shanghai Gold Exchange is generally 999.9%, or 999.7%. The former has reached the standard of 10,000 gold, but in the process of making jewelry, the need to add solder to the casting will have an impact on the purity. Although it is theoretically feasible and exists, there is no standard support in actual operation, and it is the only one in China's jewelry industry. The mandatory national standard "Regulations and naming methods for the purity of precious metals for jewelry" can not find the identity of gold with a gold content of 999.9%. In short, "100 million gold" is not a national standard, but an enterprise standard. In contrast, gold bars do not have solder problems, so the purity of gold bars is often better than gold jewelry.
First of all, Wanjinjin is the purest gold jewelry, purer than pure gold. Its value lies in its highest purity, in its technology and process of achieving the highest purity, its aesthetic value and collection value are naturally highlighted.
Because the hardness of gold jewelry is low, it should be handled gently when wearing it. Avoid rubbing and rubbing against hard objects. Do not pull, pull or smash. In particular, diamonds can be rubbed against each other due to different hardness, so they are stored separately using jewelry boxes.
TIPS vigilance (thousands) full gold plus "铱"
Some unscrupulous merchants often add 铱 elements to the (thousands) of gold to make huge profits.铱In the periodic table of chemical elements, it is close to gold. Its density is very similar to gold, but the price is five to one tenth of gold. The market price per gram is only 50~90 yuan, but each The market price of gram gold is 300~400 yuan, and the disparity difference induces some merchants to impersonate gold.
How to choose gold
Gold has a unique golden yellow luster, and pure gold shines under intense light.
Seven greens, eight yellows, nine belts are red, and four or six are not gold. Gold containing 70% gold is blue-yellow, gold containing 80% gold is yellow, gold containing 90% is red-yellow, color is less than 60% gold, and the color is yellow in yellow.
There is no sound on the floor, pointing to the mark. The high-quality gold is thrown to the ground without sound and no stretch; the low-quality gold sound is slightly brighter. Pure gold is soft and soft, and nails can be used to print marks.
Be cautious when avoiding being cheated
(1) Receipt standardization "gold content"
For the quality of gold products, the national standards have very clear regulations, that is, each piece of gold jewelry sold by the merchant must be listed to indicate its gold content and weight. At the same time, because the industry-used terms such as “Wanju Goldâ€, “Pure Gold†and “24K Gold†are not included in the standard specifications, only the receipts of industry terms (no gold content) are marked in the case of disputes between buyers and sellers. Making it difficult for consumers to defend their rights, resulting in claims that are unfounded.
(2) The high detection cost can be shared with the merchant
Compared to the value of jewelry, inspection costs are more expensive. This high cost of rights protection is also the reason why most consumers choose not to pursue the case when they encounter infringement. The insiders remind consumers that once the amount of gold in the jewelry is determined to be tricky, they should report it to the relevant departments in time, and negotiate with the merchant to check the cost sharing. Under normal circumstances, the cost of testing is first paid by the consumer. If the quality of the jewelry is detected, the merchant must compensate the consumer for the loss and accept the punishment from the relevant department.

K gold calculation method: The formula for calculating the gold content of K gold is: K value ÷ 24 × 100% (that is, K value × 4.1667%)
24K gold can also be called thousands of gold
It is the gold with the highest gold content in K gold. It usually refers to gold products with a content of more than 98%. China stipulates that gold with a content of 99.6% or more (including 99.6%) can be called 24K gold. 24K gold and Qianjin gold are basically the same, but the difference in gold content is a little bit different (less than or equal to 0.9%), so people will call 24K gold as thousands of gold.
White K gold is not platinum
