True or false: Shape is the most important factor in a rough diamond's potential value.

• A. TRUE
• B. FALSE
• C. Depends on weight
• D. Depends on color

Answer: (A)

Shape largely determines how much of a rough diamond’s weight can be turned into a marketable polished gem. A rough with a favorable shape tends to yield less waste during cutting, so more carat weight stays in the finished stone. That directly influences potential value, because size is a major driver of price. Shape also gates which cuts are practical and how the final gem will perform optically; a good shape can enable cuts that maximize brilliance and appeal, attracting buyers willing to pay a premium. While weight (carat) matters a lot, if the rough’s shape forces heavy waste or limits desirable cuts, its value ceiling drops. Color matters too, but shape has the strongest impact on how much value can realistically be realized from the rough. So the statement aligns with that perspective.
