Lab grown diamond bulk provider 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. Find additional info on https://www.messigems.com/hpht-diamond.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.
Lab Diamond Methods: Lab grown diamond are divided into CVD (Chemical Weather Deposition) cultivation and HPHT (High Temperature High Pressure) cultivation, which have their own advantages and disadvantages. First of all, let’s talk about HPHT, this is a laboratory chamber, put a crystal seed and metal catalyst, through the control of high temperature and high pressure environment, so that the diamond powder dissolves and then form diamond crystals.
But ash diamonds, can be arbitrarily selected red, yellow, blue and green: for example, control the nitrogen content will be able to create orange-red or light yellow diamonds, control the boron element will be able to create blue diamonds, like colored diamonds, it is difficult not to be moved. Moreover, the vast majority of colored urn diamonds are even less expensive than white urn diamonds, because making white requires extracting the purest carbon and a higher technical threshold. Natural diamonds can never be directly linked to any individual, but cultivated diamonds, whose “DNA” is the wealth code, can.
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.

The wax is poured into a gold mold, and the customization is usually done using the lost wax casting method to make the wax mold into an 18K ring. If it is mass produced, then the wax mold is mass produced by making the front wax plate into a silver plate pressed into a gelatin film. A more delicate polishing is done to trim the overall gold mold shape of the jewelry set. All the molding is done by hand, using special calendars to push back and forth on the surface of the jewelry, which requires the craftsmen’s exquisite skills and techniques that have been accumulated over the years, and the professional craftsmen have more than 15 years of experience on average, with exquisite skills to ensure that there will be no delays in the work schedule.
