With the continuous development of economy, people's demand for various gems is increasing, but gem resources are limited. With the deepening of mining, various gem resources are increasingly scarce. How can we resolve this contradiction? Of course we are looking for something that can replace natural gems. Synthetic gemstones came into being in this context.
As consumers, it seems difficult for people to accept synthetic gems. Many times, when people hear the word "คอมโพสิต", they suddenly reject it and feel that what is synthesized is fake, นั่นคือ, กระจก. This is exactly a wrong view to be corrected.
Synthetic gems are not fake gems, let alone glass!
Synthetic gemstones have exactly the same chemical composition, physical properties and crystal structure as the corresponding natural gemstones. Synthetic gemstones are still crystals, which are essentially different from non-crystalline glass. Synthetic ruby has exactly the same composition as natural ruby, and its luster, ความแข็ง, ความหนาแน่น, refractive index and other physical properties are exactly the same as natural ruby. The only difference between them and natural gems is the growth environment. Natural gems grow in nature while synthetic gems grow in the laboratory.
Leaving aside the rarity for the time being, synthetic gems are superior to natural gems in terms of color and clarity, considering the quality of gems alone.
In the millions of years of natural gemstone formation, the surrounding natural environment cannot remain unchanged. Any environmental change may cause color differences and leave marks in the gemstones in the form of flaws. อย่างไรก็ตาม, the laboratory can provide an extremely stable and ideal growth environment, and the gems grown are uniform and rich in color, with almost no flaws. Think of the various artificial zircons we see on the market. They are super bright and dazzling, ไม่มีที่ติ, and can completely replace any gem. Synthetic gemstones can also grow to a size that is beyond the reach of natural crystals, allowing many exaggerated designs that could only stay on paper to be processed into finished products.
There are many ways to synthesize gemstones, and the equipment requirements of each method are different, and the synthesis cost is also different. The price of the same gemstone synthesized by different methods will be quite different. Taking synthetic rubies as an example, the price of rubies synthesized by flame melting method is very cheap, and the price of rubies synthesized by hydrothermal method of the same size may cost several thousand yuan. No matter what synthetic method is used, the price of synthetic gems is quite cheap compared to natural gems of the same color and clarity level due to their lack of rarity. If it is not for investment and pure decoration, why not choose synthetic gemstones that are beautiful and affordable?
