1. The color of CVD grown diamonds can be changed
The color of natural diamonds can also change due to other elements added during the growth process, and some are caused by defects in the crystal structure. For example, yellow diamonds may change color due to the influence of nitrogen during growth, blue may change color due to boron, and green may result from radiation causing carbon atoms in the crystal structure to deviate from their normal positions.
CVD diamonds can change the color of the stone by adding color-producing elements to hydrocarbon gases during the growth process of its seed disc. Currently, large carat pink, blue, and yellow diamonds are available, and some are of very good color. Even GIA calls it Fancy Intense or Fancy in its report.
2. The biggest advantage of CVD grown diamonds is that they are purer inside.
We have introduced the manufacturing method of CVD diamonds before. Since the growth environment of CVD diamonds has a higher gas content than HPHT diamonds containing metal co-solvents, the biggest advantage of CVD diamonds is that they are very pure inside. The clarity is generally vvs1-si1, and most can reach VS2 or above.
Diamonds are composed of different elements. Diamonds can be divided into four types according to their composition, namely Type IaA (containing nitrogen in the atomic structure), Type Ib (containing irregularly arranged nitrogen), and Type IIa (pure carbon). ), Type IIb (contains boron, the common cause of color in blue diamonds).

Diamond Diamond is the hardest naturally occurring substance currently found on Earth. Diamond has a Mohs hardness of 10, and its absolute hardness is 4 times that of corundum and 8 times that of quartz. There are two main methods for synthetic diamond, high temperature and high pressure method and chemical vapor deposition method. Diamonds are used in a wide range of applications, such as crafts, cutting tools in industry, and precious gemstones.
Do lab-grown diamonds have color grades? Will lab-grown diamonds turn yellow?一. Are there color grades for lab-grown diamonds?The most common color of lab-grown diamonds is colorless and transparent. However, if you look closely, some lab-grown diamonds are actually slightly yellowish in color. Ther
