Many people who want to invest in jadeite are eager to know the preservation methods of jadeite. The preservation of jadeite is closely related to the size of jadeite, the adjustment of the international market price system, and the data proof of relevant appraisal institutions. 1. There is no specific standard for jadeite industry, but the function of preserving and increasing the value of jadeite mainly depends on jadeite:

① Matching degrees 4c and 4c refer to weighing (ct), clarity, color and luster (cutting), and the higher the index matching degree, the more valuable it is;

(2) the cost performance at the time of purchase, the higher the cost performance, the more value added;

(3) Grade, the grade of jadeite is high, and it is possible to preserve the value with natural value-added function. 2. Of course, if you want to buy jade to preserve the value, you must buy large particles, especially 1 g or more, high color and jade. After all, there are too many broken jade, which is just decoration at best. Jade is naturally rare. If you want to invest in jade, you should even aim at more than 3 grams of jade. Most jadeites with weight 1 g may not increase much! Therefore, if you want to invest in jadeite, try to choose jadeite with a larger gram. 3. Each piece of jadeite regularly produced carries a certificate, which includes the serial number, grade, quality, purity, shape, quality and value of jadeite, and the certificate issued by an authorized institution is highly recognizable. 4. After purchasing jewelry products, merchants must issue formal invoices, save and pay attention to the contents of the endorsements of the invoices, so as to actively protect their rights in case of damage to their own interests. The so-called "jade preservation" can only be understood as jade ornaments that originally sold for 20,000 yuan will now sell for 25,000 yuan under the premise of rising prices in the international market, but this price fluctuation is only reflected in the retail field. For ordinary citizens, buying jade ornaments should be regarded as consumer goods, not hard currency that can be cashed at will. Only those wholesalers who can directly buy jadeite at international quotation and can throw jadeite at international quotation at any time are eligible to enjoy "jade preservation". It is difficult for ordinary consumers to preserve the value of jadeite, and there is a lot of concern about our jadeite merchants investing in jadeite. The average consumer has never thought about when to buy jade or what jade is like. Many people buy bracelets, jade necklaces and so on. And I still wear it all the time. However, for such a rare and precious thing as jade, there will be great room for future appreciation. After all, things are rare!
