Hpht diamonds wholesale supplier right now: Natural diamonds have the same physical and chemical characteristics as lab grown diamond, both being three-dimensional crystalline minerals formed from the element carbon, the main difference being the way in which they are formed. Natural diamonds grow hundreds of kilometres from the surface in the high-temperature, high-pressure lower mantle, and take millions of years of crustal movement to reach the surface of the earth in volcanic eruptions before becoming a mineable mineral, whereas lab grown diamond are formed in a matter of weeks in a human-cultivated environment. The physical and chemical properties of the finished cultivated diamond are not dissimilar to those of a natural diamond. Read more info at wholesale lab grown 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.
The CVD cultivation method means that a thin diamond wafer is used as a seed and placed in a cultivation tank to artificially simulate the growth environment of a mineral diamond, causing carbon atoms to accumulate on the crystals to form a rough diamond. Diamonds grown by this method are llA diamonds, which are very clean and translucent. Most of the diamond colors are FGH, and the DE colors are less. If you want to choose a better and safer Lab grown diamond, we recommend you choose a CVD diamond, and if you want to choose a slightly lower price, go for HPHT (if you are not afraid of not being able to pass the diamond tester), but compared to natural diamonds, the price of Lab grown diamonds is already very low, and you have already saved a lot of money, so we don’t feel the need to save that little bit of money.
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.
When considering the purchase of a 1 carat lab-grown diamond, one should take into account several factors that can affect its quality and price. For example, the color, clarity, and cut of the diamond can all influence its appearance and value. Additionally, it’s important to verify that the lab-grown diamond has been certified by a reputable authority, such as the Gemological Institute of America (GIA) or International Gemological Institute (IGI), to ensure that you’re getting a high-quality diamond.
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.
Natural gas and hydrogen are heated to form a carbon plasma in a dishwasher-sized pressure chamber, which is deposited on the carbon substrate at the bottom of the chamber and gradually accumulates and hardens to form diamond flakes, which are then cut into gemstones. The shape is then cut into gemstones. Compared to other types of synthetic diamonds, CVD diamonds can be produced in larger sizes and with greater precision. They can also be created with specific characteristics, like specific colors or the ability to conduct electricity, making them useful in a range of industrial applications, including cutting tools, electronics, and optics.

Someone once drew an analogy: comparing a natural diamond with a cultured diamond is like comparing a natural baby with a baby born to a surrogate mother; after all, they are all human beings! Like people, diamonds are divided into beauty and ugliness. Beautiful, will be sent to go to high-end jewelry stores, become the most striking existence; looks average, will be packaged and polished a little in the ordinary people’s families, witness love and life; ugly, most of the factory to do abrasive. So how are diamonds graded? As you should know, diamonds are made up of carbon atoms. Diamonds are roughly divided into four main types: Type Ia, Type Ib, Type IIa, Type IIb (1a, 1b, 2a, 2b), of which 1a accounts for 98% of the total amount of diamonds mined worldwide, 2a accounts for less than 2%, and there are very few natural 1b and 2b.
