“黄色钻石分级(英文版)”介绍
Yellow diamonds are graded based on their color intensity and clarity, among other factors, to determine their value and rarity in the market. The color of a yellow diamond can vary from faint to vivid, with the most sought-after hues being vibrant and intense. In addition to color, the presence of inclusions or blemishes is also assessed, as they can affect a diamond's transparency and light performance. Furthermore, the cut quality plays a crucial role since it influences the diamond's ability to reflect and refract light, showcasing its natural beauty. These evaluations are meticulously carried out by professional gemologists using specific grading scales, ensuring that each yellow diamond is classified accurately according to industry standards.
