The division rule of brushing and grinding is to observe the thickest area of the waist from the side under the condition of 10 times magnification. According to the severity of brushing and grinding, it can be divided into four levels: none, medium, obvious and serious.

In the cutting and grinding process of round diamonds, in order to minimize the loss of carat weight of round diamonds and eliminate the flaws near the girdle, the processing method of changing the inclination angle of the upper and lower girdle facets is adopted, and the method of reducing the inclination angle of the upper and lower girdle facets is adopted. It is called painting, and the method of increasing the inclination angle of the upper and lower waist facets is called digging out.
Brush grinding refers to the girdle thickness between the connecting points of the upper girdle facets and the lower girdle facets (A, B) of round brilliant cut diamonds, which is smaller than the girdle thickness between the kite face and the pavilion main facets (C, D place) phenomenon.
Polishing refers to the phenomenon that the girdle thickness (A, B) between the connecting point of the upper girdle facet and the lower girdle facet of the diamond is greater than the girdle thickness (C, D) between the kite face and the pavilion main facet .
The division rule of brushing and grinding is to observe the thickest area of the waist from the side under the condition of 10 times magnification. According to the severity of brushing and grinding, it can be divided into four levels: none, medium, obvious and serious. Various degrees and combinations of brushing and chipping affect the ratio grade, with severe brushing and chipping reducing the ratio grade by one step.

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
