Diamond rough is sorted into categories based on which characteristics?

Diamond rough is sorted into categories based on which characteristics?

• A. size, shape, clarity and color
• B. weight, origin, and durability
• C. age, origin, and provenance
• D. fluorescence, cut, and polish

Answer: (D)

Rough diamond sorting is about factors that determine how the stone will perform once it’s cut and finished. Fluorescence affects how the diamond looks under certain lighting and can influence value, so it’s a key way to categorize rough. Cut potential matters because it predicts how well the rough can be shaped into a well-proportioned gem, affecting yield and brilliance. Polish potential is about how smoothly a finished surface can be achieved from that rough, which again impacts the final appearance and value. Together, these characteristics focus on the end result—the gem’s appearance and value—rather than just the stone’s size, origin, or other history-related aspects.
