First, grasp the identification link. Because jewelry is expensive, collectors must buy it from regular jewelry stores and counters with high credibility. Or directly entrust the factory to customize is also an ideal collection channel.
Second, don't buy cheap ones. Jewelry discounted due to defects has basically lost its value-added function. You can also participate in the jewelry auction, which is a place where the circulation of high-grade jewelry is relatively concentrated, and at the same time you have the opportunity to get some inexpensive gems.
Third, understand the market price. The price of jewelry will change with the supply and demand of the market, so there are certain risks in collecting gems. We should keep abreast of the changes in the market in various ways and make use of price fluctuations to gain greater benefits.
Care must be taken when keeping jewelry and precious stones to prevent unnecessary losses.
