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.

Why Are Large-Size Single-Crystal Diamond Heat Sinks Manufactured Using a Mosaic Assembly Process?
In the packaging design of 5G RF power amplifiers, automotive VCSEL radars, high-performance AI chips, and high-power industrial lasers, large-area single-crystal diamond heat sinks measuring 35 mm or larger are an essential requirement. Most procurement and thermal design engineers ask the same question: Why do 25×25 mm single-crystal heat sinks on the market tend to use a mosaic assembly structure? This is not due to a simplification of manufacturing processes, but rather because of unavoidabl

The Metamorphosis of Diamond: From Jewelry to a Cornerstone of Technology—Three Key High-Tech Applications of CVD Single-Crystal Diamond Wafers
When you hear the word "diamond," what comes to mind first? Is it dazzling diamond jewelry, or the romantic vow that "a diamond is forever"? In reality, diamond is making a major breakthrough in the realms of industry and technology—demonstrating its value in a truly "hardcore" way. Thanks to its status as the hardest material in nature, its exceptional thermal conductivity, and its broad optical transparency (spanning from ultraviolet to infrared), CVD (Chemical Vapor Deposition) single-crystal
