Hpht diamonds bulk supplier from China: 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. See additional details at https://www.messigems.com/lab-grown-diamonds.html.
Cut, round diamonds are divided into three categories: cut, polish and symmetry. Cut diamonds are two points. A good cut will make the diamond more colorful, which determines the sparkle of the diamond. Cut is categorized from high to low as ideal, excellent, very good, good, weak, and poor. The higher the cut recommendation, the better it is, the icing on the cake for the diamond. Also pay attention when choosing the quality of diamond, it is recommended to choose the non-fluorescence level, fluorescence will cover part of the diamond fire color. Finally, pay attention to avoid the selection of diamonds of coffee, milky, green, will also affect the beauty of the diamond. You can refer to the above points when selecting a diamond for cultivation. I hope you have a pleasant shopping experience.
If you know anything about diamonds, you should know that since its founding in 1888, De Beers has monopolized almost 80% of the world’s natural diamond , so the price of natural diamond remains high. As a giant in the diamond industry, De Beers can’t afford to let diamond mining grow wildly. So take the initiative, in 2018 officially launched the cultivation of diamond brand Lightbox, claiming that $800 can buy a carat of bare stone, but does not come with a certificate, so the diamond grade is also vague. In addition, it is often out of stock, making it difficult to buy.
First, let’s talk briefly about Lab grown diamonds, which are diamonds grown in a laboratory using certain techniques and processes to produce crystals with the exact same appearance, chemical composition, and crystal structure as natural diamond. A simple analogy can be made to say that natural diamond are ice formed in the wild, while Lab grown diamonds are ice formed in the refrigerator. Lab grown diamonds are environmentally friendly, have outstanding sustainability benefits, and are far less expensive than natural diamonds. Of course, Lab grown diamonds are also divided into three, six, nine grades, so if you want to choose a good diamond in all aspects, you can refer to the following points.
There are also companies that sell ashes diamonds that say it’s not comparable to natural diamonds, “because ashes diamonds have a priceless memorial significance, and it contains a unique and non-transferable emotion.

Red lab grown diamond: Red lab grown diamond are synthesized by HTHP method Ib type diamonds, after irradiation treatment blue or blue-green, again heating treatment, you can get pink and fuchsia lab grown diamond. Green Lab grown diamond: Natural green lab grown diamond are affected by natural radiation will produce GR1 absorption, then the lab grown diamond appear green, you need to put the lab grown diamond into artificial irradiation equipment, such as cyclotron, electron irradiation treatment, neutron irradiation treatment, through the above methods can get green synthetic diamonds.
Natural diamonds grow in multiple directions under high temperature and high pressure for a long time. Cultivation of diamonds hthp simulates the high temperature and high pressure multidirectional growth in the underground environment. Cvd is the high temperature and high pressure unidirectional growth in the reactor. All diamonds over 0.5 ct come with a certificate of authenticity.The quality of each lab-grown diamond is certified by a certificate of authenticity issued by the International Gemmological Institute (IGI), which is recognized by diamond exchanges around the world for its strict quality standards.

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.
