Which term refers to an irregular girdle surface?

• A. Rough Girdle
• B. Scratch
• C. Scintillation
• D. Selective Absorption

Answer: (A)

The girdle is the diamond’s outer edge. When that edge isn’t smooth, graders describe it as a rough girdle to indicate an irregular surface along the girdle, with unevenness that can affect appearance at certain angles. Scratches are surface marks that can occur anywhere and don’t name the girdle’s texture specifically; scintillation refers to the sparkle pattern of light, not the girdle’s surface; selective absorption describes how the diamond absorbs certain wavelengths, often related to color or fluorescence. So, the term that directly refers to an irregular girdle surface is rough girdle.
