High quality Hpht diamond wholesale manufacturer: The production process for lab grown diamond has become more mature and offers advantages in terms of quality and cost effectiveness compared to natural diamonds. Lab grown diamond have an advantage over natural diamonds in terms of average quality, as they are usually classified as types Ia, Ib, IIa and IIb, depending on the level of inclusions. Type IIb diamonds contain boron and therefore exhibit a blue colour and are extremely rare in their natural environment. Currently the majority of lab grown diamond from head producers are Type IIa, with only 2% of natural diamonds being of this type. At the downstream retail end, the majority of lab grown diamond are D-F in colour, while the majority of natural diamonds are G-I in colour. Lab grown diamond are better than natural diamonds in terms of value for money. Find more information at hpht diamond.
Clarity, which represents the internal flaws of the diamond. It is categorized into FL Flawless, where no inclusions are visible under 10x magnification, VVS, Very Slightly Included, where very small inclusions are visible under 10x magnification. This grade is a collector’s item and is very rare. vvs grade, Very Slightly Included, tiny inclusions visible under 10x magnification. vs extreme, Slightly Included, tiny inclusions visible under 10x magnification. si micro inclusions, inclusions visible under 10x magnification. l grade, inclusions that may be visible to the naked eye if some large diamonds are on the surface. Some large diamonds may also have inclusions that are directly visible to the naked eye if they are on the surface. l grade, inclusions are more easily seen directly by the naked eye and can affect the brilliance of the diamond.
Through high temperature and high pressure to reduce the brown color of diamonds, so this method of cultivation of diamonds with high color grades, but the individual will have a phosphorescent reaction, this will not be reflected in the certificate. HPHT clarity is relatively poor compared to the CVD, because of the use of metal catalysts in the cultivation process with metal catalysts, which leads to diamonds will be inside the metal residue, the severity of which will be sucked up by the magnets, so a lot of HPHT diamonds can’t pass the diamond tester pen and will be measured as moissanite reaction.
Lab Grown Diamond Certificate: The reason why certificates are at the top of the list is because they are an essential partner of the diamond. How to guarantee the authenticity of the parameters of the diamond, it depends on the authority of the certificate. The most comprehensive is IGI (International Gemological Institute), both electronic and paper version, very perfect, 4C, cultivation methods, whether to change the color and anti-counterfeiting. However, it should be noted that IGI has several testing points, India, the United States and Shanghai, China, and the most important thing to note is that the certificate from India can be double-checked and dropped. The best one is the certificate verified by IGI in Shanghai, China. It is also best to check the waist code when buying and choose a reliable dealer.
Recently, a small red book on the topic of “died puppy into a diamond” fire, the blogger said, in memory of the deceased love pet, she collected puppy ashes and her own hair, handed over to the company carbonized into a diamond ring. The price of these artificial diamonds is not expensive, one carat of loose diamonds plus the setting process will require more than 40,000 yuan, and can be customized, the style of change has no upper limit, but the price is the average worker can not afford.
Natural diamonds are more difficult to mine and more expensive, and colored diamonds are even rarer and more expensive. Lab grown diamond have entered the public consumption field, but many people do not know enough about fancy color lab grown diamond, so how their color is made? Colorless lab grown diamond: Colorless lab grown diamond are produced using the HTHP method and the CVD method. The HTHP method used to produce diamonds has the element N in its composition, which is why our lab lab grown diamond appear yellow. In order to produce colorless diamonds, the N element must be absorbed, so diamonds produced by the HTHP method are colorless type IIa.
One of the key advantages of CVD diamonds is their purity. Because they are created in a controlled environment, they do not contain many of the impurities typically found in natural diamonds or other types of synthetic diamonds, such as boron or nitrogen. This makes CVD diamonds particularly well-suited for use in high-precision scientific instruments or as gemstones in jewelry. Overall, CVD diamond technology has advanced significantly in recent years, leading to increased production efficiency, higher quality results, and a wider range of applications.

Nitrogen impurities, low quality, various forms of impurities will affect the color of the diamond itself, so there will be colorless, yellowish, brown and so on a variety of colors, generally according to the quality of the use of the decision, can be used for jewelry, industry and so on. 1b: Nitrogen impurities are abundant, but the nitrogen contained is in monatomic form, resulting in an overall yellow color, ranging from dark to light. There are very few natural diamonds of this type in stock, but the HPHT factory in China produces them on a daily basis, covering more than 90% of the world’s production capacity. Synthetic diamonds of this type are used as cutting tools or abrasives.
