According to whether the diamond contains N or does not contain N, the diamonds
”
According to whether the diamond contains N or does not contain N, the diamonds are divided into type I diamonds and type II diamonds, and then divided into type Ia diamonds and type Ib diamonds according to the different forms of the original N in the crystal lattice.
Diamonds are divided into type IIa diamonds and type IIb diamonds according to whether they contain P or contain P.
Type I Diamond | Type II Diamond | |||
TypeⅠa | TypeⅠb | Type Ⅱa | Type Ⅱb | |
The N content is 0.1%-0.3%, and N exists in the form of small aggregates in the diamond crystal. | The N content is<0.1%, and the N is in a separate dispersed state in the diamond crystal. | No N, no P | No N, a small amount of P | |
color | white,fancy vivid yellow | white、fancy light yellow、brown | white、brown、pink | blue、gray |
Type Ia diamonds:
N atoms come in the form of N atom pairs or N3 centers, the more N3 centers, the yellower the diamond. 98% of natural diamonds are type Ia.
Type Ib diamonds:
N atoms exist alone, most of which are synthetic diamonds. Under certain temperature, pressure and time, type Ib can be transformed into type Ia diamond.
Type IIa diamonds:
N atoms exist in a free state and have good thermal conductivity. The thermal conductivity at room temperature is 5 times that of copper. It is an excellent heat dissipation material in the electronics industry.
Type IIb diamonds:
It is a semiconductor, the only one among diamonds that can conduct electricity, and can be used as a thermal sensor to measure temperature.

Z-Axis System: The Key to Stable Production of MPCVD Diamonds
Microwave Plasma Chemical Vapor Deposition is the mainstream method for producing high-quality diamonds in the industry. When the equipment is running, it first pumps the reaction chamber into a vacuum state to strictly ensure the chamber is fully sealed and airtight. Then, the microwave device releases energy, and special mixed reaction gases are fed into the chamber. Under the action of energy, a stable plasma area is formed. These highly active plasmas provide stable heat and reaction conditi

CVD Diamond Clarity: How to Avoid Inclusions That Affect Jewelry Value
After selecting a loose diamond, the setting not only determines the diamond’s security but also directly affects its perceived size. With diamonds of the same weight, choosing the right setting design can effortlessly create the surprise of “small carats making a big impact,” saving on your budget while enhancing the diamond’s quality. Among these, pavé and prong settings are the two most classic and effective ways to make a diamond appear larger. Paired with specialized designs that maximize t
