Fire is the colored light reflected by a diamond. Dispersion refers to the phenomenon that white light is decomposed into a continuous spectrum composed of monochromatic light of different wavelengths when it passes through the inclined surface of a transparent object, thereby forming a phenomenon of spectral color, which is also called "fire color".

Fire is the colored light reflected by a diamond. Dispersion refers to the phenomenon that white light is decomposed into a continuous spectrum composed of monochromatic light of different wavelengths when it passes through the inclined surface of a transparent object, thereby forming a phenomenon of spectral color, which is also called "fire color".
The dispersion effect of a material is expressed by the difference in refractive index between blue light (430.8nm) and red light (686.7nm) of a specific wavelength. This difference is called the dispersion rate. A gemstone with a larger dispersion rate has a stronger dispersion effect and stronger fire; the dispersion value of a diamond is 0.044, which is a gem with strong dispersion, so a diamond has a strong fire.
When a beam of white light is irradiated vertically on the table, the white light will not be dispersed on the table; but when the light enters the facet of the inner pavilion of the diamond from the crown, it is totally reflected by the facet, and then passes through the surface of the crown. The oblique facets are refracted, and the purple light and red light form fire due to their different refractive indices. As the incident angle increases, the dispersion effect is also enhanced, and the fire is more obvious.

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
