"Diamond-DET"

"As a typical extreme functional material, diamond possesses ultra-high hardness, excellent thermal conductivity, and outstanding optical and chemical stability. Known as the \u201cindustrial tooth,\u201d diamond plays an irreplaceable role in precision machining, electronic devices, optical engineering, and high-end manufacturing. It also holds an important position in jewelry due to its high refractive index and unique optical appearance. Restricted by natural conditions, natural diamonds have limited reserves, high production costs, and unstable quality, making it difficult to meet the large-scale and standardized demands of modern industry and consumer markets. In recent years, with the rapid development of synthetic technologies such as High Temperature and High Pressure (HPHT) and Chemical Vapor Deposition (CVD), artificial diamonds have gradually replaced natural diamonds owing to their controllable size, stable performance, and high efficiency.Diamond clarity, which reflects internal and surface imperfections, is a key indicator for evaluating diamond quality. During synthesis, defects including cracks, pits, and impurities may appear on the diamond surface, while internal flaws such as inclusions often occur. These defects vary significantly in shape, size, and distribution, and jointly determine the clarity grade. High-clarity diamonds have higher quality and economic value, and different grades correspond to different application scenarios. Therefore, accurate diamond clarity detection is of great significance for improving product competitiveness and realizing economic benefits."
