1. Under the existing conditions, not all gems can be synthesized. Accurately speaking, only a few precious stones can be completely synthesized, such as diamonds, rubies and sapphires. And synthetic gems can't be exactly the same as natural gems. Take ruby and sapphire for example, after so many years of research and development, the technology has gradually matured, and the synthetic products have gradually approached the characteristics of natural gemstones, but there are still many identification methods. Synthetic rubies and sapphires have natural curved ribbons, curved growth lines, spherical tadpole-shaped bubbles, bright red fluorescence and so on. Therefore, I think that for people in the jewelry industry, synthetic gems should not and will not be an obstacle to gem collection. Jewelry lovers outside the industry can focus on professional appraisal certificates equipped with gems.

2. In addition, China people are very strict about jewelry, and they must demand perfect absolute natural gems, but they are very resistant to synthetic or optimized gems. So although the technology of synthetic jewelry has become more and more perfect in recent years, it still can't open the domestic market. Thus, for the collection of high-grade natural jewelry in China, synthetic gems have no chance to replace them.

Compared with precious metals, I personally suggest paying attention to the collection of precious stones. The reserves of high-grade gems are limited, especially high-end gems. The world output is definitely decreasing, and it may even stop production in the future. In the long run, the appreciation space of this kind of stone is immeasurable. The price of precious metals is closely related to the world economic situation, and the domestic price is also very unstable. Some people in the jewelry industry get rich overnight because of investing in precious metals, but more of them are ruined.

3. If it is used as decoration, just choose your favorite jewelry regardless of other factors. If you want to preserve and appreciate as a collection, you should still choose high-end gems. For example, if you buy a jade bracelet of 1 0,000, it will still be 1 0,000 five years later. If you buy 5 million jade bracelets, it will probably double in five years.
