Which term refers to testing for the size, shape, clarity, and color of the diamonds in a deposit?

• A. Character sampling
• B. Bruting
• C. Bruise (Br)
• D. Burn Marks (Brn)

Answer: (A)

Character sampling focuses on describing the overall character of a diamond population in a deposit—the typical size range, shapes, color distribution, and any clarity features seen in rough stones. By taking representative samples from the ore, you can learn how the diamonds are likely to behave as a group, which helps guide mining and processing plans. This is exactly what testing for size, shape, clarity, and color in the deposit aims to uncover: the distribution and nature of the diamonds present. Bruting is the cutting process that shapes a rough diamond into a round form, so it isn’t about assessing the deposit’s characteristics. Bruise (Br) and Burn Marks (Brn) are types of damage or defects that can appear on stones, not sampling methods for evaluating a deposit.
