There are two main manufacturing methods for lab grown diamond, one is the high-temperature high-pressure method (HPHT), and the other is the chemical vapor deposition method (CVD). HPHT high-temperature and high-pressure diamond synthesis uses the principle of high-temperature and high-pressure to simulate the growth environment of diamond, which can also produce high-quality diamond. HPHT is a relatively traditional diamond cultivation method, which uses a special device in the laboratory to simulate the high-pressure and high-temperature environment (about 50000 atmospheric pressure, 1300-1600 ℃) during the formation of natural diamond deep in the Earth, and uses the carbon materials inside the device to manufacture and cultivate diamond.

Secondly, the IGI certificate, fully named International Gemological Institute, was established in Antwerp, Belgium in 1975. It is currently the world’s largest independent jewelry appraisal laboratory and gemological research and education institution, and has created the 3EX cutting evaluation system. This is also the internationally recognized standard diamond cutting grade evaluation method, and IGI has developed the world’s first complete and comprehensive diamond cutting rating table, This has also become the prototype of modern diamond cutting system evaluation standards. IGI has laboratories and schools in major diamond trading centers and central cities around the world, and gemologists from over 96 countries worldwide receive IGI’s laboratory and educational research services. It is known as the “authoritative appraisal agency around consumers”.

The original moissanite diamond came from the vast stars. About 50000 years ago, it landed on the earth with meteorites. Until 1893, it was discovered in the crater by Nobel laureate Dr. Henry Mozambique and named as Mozambique. It was this discovery that made everyone focus on the moissanite stone. One hundred years later, the North Carolina Laboratory developed a large Mozambique stone for decoration with high technology for the first time. In June 1998, Charles Kova moissanite Diamond Company (C3) in the United States invested $45 million in the development of the perfect diamond substitute, moissanite Diamond, combining high-end technology and technology. Once this substitute was introduced, it became famous for its sparkling colors, causing countless international sensations and increasing demand. Initially, the moissanite diamond was a patented product of Charles Kova moissanite diamond (C3) in the United States. However, a few years ago, the patent had already expired. As a result, companies of all sizes around the world began to produce and sell moissanite diamonds, and the price of moissanite diamonds was significantly reduced.

Lab grown emerald is based on natural mineral components of emerald as raw materials, simulating natural environments in the laboratory, allowing emerald to recrystallize and generate, with the same composition and gem characteristics as natural emerald. Lab grown emerald to grow in modern laboratories is a product of technological development. It uses “thin slices of grandmother emerald” as the “seed By imitating the high-temperature and high-pressure environment formed by natural emerald, technicians can precipitate the dissolved chemical elements onto the seeds of emerald, ultimately leading to the birth of cultivated emerald.

Lab grown emerald is not a “fake gem” or a “substitute” for gemstones, but a laboratory grown emerald with a structure consistent with natural emerald. Lab grown emerald and natural emerald have many similarities. First, they are identical in appearance, and natural emerald and lab grown emerald cannot be distinguished by naked eyes alone. In professional appraisal institutions, it is only with the help of professional instruments that they can be clearly distinguished from the growth patterns. Secondly, both have the same basic attributes. The price calculation mode of both is also the same, and their prices are determined based on carat size, gemstone color, gemstone cutting, gemstone clarity, and later processing. Colombia lab grown emerald, achieving the most authentic inclusions and natural colors, and is currently the closest variety to natural emerald.
