What is the single most important value factor for a cuttable rough diamond?

• A. Carat
• B. Color
• C. Shape
• D. Clarity

Answer: (C)

Shape is the most important value factor for cuttable rough because it determines how efficiently the rough can be planned and cut into a marketable final gem. A favorable shape allows you to maximize yield with the desired final form (often a round or other premium cut), minimize waste, and achieve a cut that buyers prize. If the rough’s shape is awkward or irregular, much of the material can be wasted or forced into less desirable final shapes, limiting size, symmetry, and overall value—even if the rough has good carat, color, or clarity. So, the ability to produce a high-quality, desirable cut from the rough is largely governed by its shape, making it the most influential value factor for cuttable rough.
