Cloud (Cld) is defined as ...

• A. A single, isolated translucent inclusion.
• B. An external feature only visible under 60X magnification.
• C. Many tightly grouped pinpoints that might be too small to distinguish individually at 10X but together have a hazy appearance.
• D. A region of colorless area within a diamond.

Answer: (C)

Clouds inside a diamond are clusters of tiny pinpoints that come together to form a hazy, milky area rather than discrete individual inclusions. The defining idea is that many small inclusions are tightly grouped, so you can’t see each one separately at around 10× magnification, but the overall effect is a hazy appearance in that region. This internal, cloud-like phenomenon is different from a single isolated inclusion, from a surface feature that would require very high magnification to notice, or from a region that simply appears colorless. So the description that matches a cloud is the one where many tightly grouped pinpoints collectively create a hazy area inside the diamond.
