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.
The most important thing to choose a diamond is to integrate the 4C of diamond. After reading these, you will know that when choosing to lab grown diamond, you need to choose large, transparent, and well colored diamond to bring you the greatest shine! Currently, GIA, IGI, and NGTC are the most authoritative certificates for lab grown diamond, with IGI certificate being the most common and mainstream certificates for lab grown diamond.
Moissanite stone has a higher luster, fire color and brightness than diamonds, making it more suitable for jewelry and a good substitute for diamonds. The moissanite diamond has a good fire color and higher refractive index. Its refracted light emits a rainbow of dazzling light. Compared with the diamond, the fire color emitted by the optical instrument is 2.4 times higher than that of the moissanite stone. The fire color light emitted by it is more eye-catching.

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.
High quality and affordable. Lab grown emerald have the same properties as natural emerald, but their prices differ by tens or hundreds of times compared to natural emerald! In order to enhance the sales appearance, most emerald in the current market are optimized, such as applying polymers (coloring) or soaking in oil.
