Diamonds have rich meanings, symbolizing romance, love, money and power. But for many people, the quality of diamonds is the main thing. These colored stones attract people to spend thousands of dollars or more to buy them. But if there were cheaper diamonds, would you choose them?
In the past ten years, laboratory diamond technology has been greatly improved to the same quality as mining diamonds. Natural diamonds and laboratory diamonds are almost the same, with pure carbon components and very similar crystal structures. Only special instruments can detect the differences.
In nature, diamonds are formed 200 kilometers below the surface of the earth. Due to the intense heat and pressure generated by crustal movement, they were brought to the surface of the crater hundreds or billions of years later.
In contrast, modern laboratory diamonds are made in the laboratory by two methods-HPHT (high pressure and high temperature) or CVD (chemical vapor deposition). No matter which method is used to make diamonds, if it is done well, it can't be distinguished by the naked eye and can only be detected in the laboratory with special instruments.
Diamonds are not only used as jewelry, but also widely used in industry, science, military and other fields. It is precisely because of the wide use of diamonds that people choose to create high-quality diamonds in the laboratory. And constantly improve the technology, improve the quality of diamonds made in the laboratory, and make it a top substitute for natural diamonds.
Although the price of laboratory diamonds is still not cheap, jewelers agree that buying laboratory diamonds with natural diamonds of the same size and color can save about 30% of the cost price.
Identification of laboratory diamonds. diamond
It is difficult to identify high-quality laboratory diamonds with ordinary equipment, and only spectral instruments can be used to detect them in the laboratory.
Why buy diamonds made in the laboratory?
1. Social Peace-In the past decades, the diamond trade in armed conflicts has been a stain on the reputation of diamonds, which has made diamonds lose their luster.
Laboratory diamonds have the beauty of natural diamonds, which makes people no longer trigger bloody conflicts because of competing for diamonds and promotes social harmony and stability.
2. Eco-friendly-no exhaustion, no need for explosives, no need for mining, which means no damage to the fragile ecological environment.
3. the crystallization of wisdom-this is a brand-new technology, a beautiful diamond created by human efforts with wisdom.
4. priceless-good quality natural diamonds are expensive, but good quality laboratory diamonds are not much cheaper than natural white diamonds, which also reflects the original meaning of diamonds: precious and rare.
5. Concept correction-Many people have exclusive ideas about synthetic gems, and associate laboratory creation with "cheap" or "fake". In fact, laboratory diamonds are "real" diamonds. Please refer to the figure below:
After seeing the data in the above picture, please don't compare the laboratory diamond with the general synthetic diamond, because it is a "real" diamond.
IGI (International Gemological Society), one of the three authoritative appraisal institutions in the world, has issued a 4C appraisal certificate for laboratory diamonds. IGI certificate is well-made and provides detailed and intuitive information. The following picture shows the identification certificate made by IGI for laboratory diamonds:
