Which characteristic is NOT used to categorize diamond rough?

• A. Size
• B. Shape
• C. Clarity
• D. Carat weight

Answer: (D)

In sorting rough diamonds, the focus is on attributes that describe the crystal’s form and how it will yield a finished gemstone. Size refers to how large the rough is in its dimensions, which directly influences how much material can be recovered. Shape describes the crystal’s overall outline and how it might be cleaved or faceted, guiding cutting options. Clarity concerns visible internal features, helping assess potential flaws and plan the best way to maximize quality. Carat weight, while important for price after cutting, isn’t a primary criterion used to categorize rough itself because it’s a measure of mass that results from the chosen cut and yield. Different cuts can produce different carat outcomes from the same rough, so carat weight isn’t a defining sorting category for the rough.
