With the improvement of living standards, more and more people are beginning to wear and collect jewelry and jade jewelry. But do you know how to choose jewelry and jade? Which kind of jewelry and jade has more value-protecting effect? ​​Today Ningbo Product Quality Supervision and Inspection Institute Ms. Zhou Suzhen, Director of the Gold Jewelry Testing Center and Secretary General of Ningbo Gold and Jewelry Association, shared the experience of jewellery and jade consumption and appreciation.
Buying low-end real goods is more scary than fakes.
Many people think that buying jewelry and jade in the country of origin is more cost-effective than buying it in China. In fact, there is a greater risk of buying in different places.
At the beginning of this year, Ms. Zhu of Yinzhou District spent more than 300,000 yuan to buy jade bracelets, necklaces and rings when she traveled abroad. The receptionist said that the local origin is the origin of jade, and this jade bracelet must be genuine. After returning to Ningbo, Ms. Zhu took these three pieces of jewelry to the Gold Jewelry Testing Center of Ningbo Product Quality Supervision and Inspection Institute. The staff issued a test report: these jewellery is natural jade. Ms. Zhu took the three pieces of goods to Ningbo's jewelry store for comparison. It turned out that similar goods could be bought in Ningbo for more than 100,000 yuan. She contacted the seller through the travel agency to request a return, the other party agreed to return the goods but charged a fee of more than 50,000 yuan, Ms. Zhu is somewhat unacceptable.
The secretary-general of the Consumer Protection Committee of Yinzhou District said that it is lucky to buy jewellery and jade outside the country, because it can be faked through the appraisal report of the professional testing center, but if you buy a real value that is not worth the money, It is a bit difficult for consumers to return in full.
In addition to accepting a large number of enterprises and institutions commissioned testing, the Gold Jewelry Testing Center of the Municipal Product Quality Supervision and Inspection Institute now receives jewellery and jade jewelry from 20 to 30 citizens every day, most of which are due to online and WeChat. After a friend's circle or overseas travel, you can buy it without worrying after purchasing jewels and jade. Zhou Suzhen said that the inspection products are mainly jade, of which 60% are authentic, which is the natural jade that people often say, but most of them are of poor quality.
Natural jewelry and artificial jewellery are much less valuable
Natural jewels are beautiful, durable and sparse. They are the essence of many mineral rocks. More than 3,000 minerals have been found in nature, and only 230 species of gemstones can be made, while only 20 of them are high-end gemstones, accounting for about 10%.
Zhou Suzhen said that jewellery and jade are divided into two categories, natural and artificial. Natural ones are divided into natural gemstones (such as diamonds, red sapphires, etc.), natural jade (such as jade, hetian jade, etc.) and natural organic gemstones (such as pearls and corals). , amber, enamel, etc.). Artificial jewels are divided into synthetic gems (such as synthetic diamonds, synthetic red sapphires, etc.), artificial gems (such as artificial garnet garnet, artificial garnet garnet, etc., which do not have corresponding natural gems in nature), and jewels ( Such as splicing rubies, flattening and jade, etc.) and re-creating gems (by artificial means, the pieces or pieces of natural jewels are welded or pressed into jewels and jade with an overall appearance, such as reconstituted amber, recreated turquoise, etc.).
The scarcity of natural jewellery and jade is difficult to meet more and more market demand, artificial jewellery and jade came into being, but the value of the two is very different. Professional testing organizations can easily distinguish between natural jewels and artificial jewels. It is difficult for ordinary people to distinguish them, but they can also understand some common sense. For example, amber and beeswax are easier to distinguish between true and false, and their density is relatively small. Put them in saturated warm salt water and float them naturally. In addition, you can also use a fluorescent flashlight to take a photo, really amber, beeswax has a strong fluorescence reaction, but whether it has been manually processed or a professional detection mechanism to distinguish. Diamonds, as long as they have a CMA/CAI/CNAS logo, will not be fake. The grading evaluation system of Hetian jade and jadeite is not as perfect as diamonds. The test certificate only distinguishes between natural and artificial, and does not evaluate the quality.
The four most valuable international precious stones
High-quality jewellery and jade are not only beautiful, but also have a value-preserving function. Zhou Suzhen believes that among all jewellery and jade, the world's most popular first diamonds, followed by rubies, sapphires and emeralds. These are the four precious gems recognized by the international jewellery industry. They are highly recognized and easy to realize. The price of Hetian jade, which has been very hot in recent years, has soared 3,000 times since the 1990s, but this irrational price increase is not recognized internationally. In comparison, although the price of diamonds has not increased much, it has great stability.
Of course, not every diamond has a value-preserving function, and diamonds below 1 carat have no value-preserving function. Under the premise of the same color and clarity grade, the price of diamonds increases step by step as the weight of the diamond increases. This is commonly known as the “carat premiumâ€. In addition, round diamonds are generally more valuable than other shapes of diamonds. The diamond industry is a high-monopoly industry all over the world. When the same quality diamonds are sold through formal channels, the exchange rate fluctuations are removed, and the prices around the world are not much different.
The same is true for gems. Weight is the primary factor in determining value. It is generally considered that red sapphires above 3 carats and emeralds above 5 carats have a relatively good quality value.
Zhou Suzhen said that if you buy jewelry and jade jewelry, don't worry about buying it. First of all, you should go to the market, understand the market, and master some basic knowledge to avoid fakes. To buy high quality jewelry and jade, the channel is also very important. In the retail market, you can buy some jewelry that is suitable for wearing, and when you invest, you have to choose a channel. Like some big international jewellery brands, one or two tastings will be held in Ningbo every year to showcase top jewellery. The jewelry purchased in such channels is of great value.
