Dealers often sort melee by size using which tool?

• A. Calipers
• B. Scales
• C. Pipes
• D. Sieves

Answer: (D)

Sorting melee by size relies on sieving, which uses screens with fixed openings to separate stones by their diameter. When a bulk of tiny diamonds is run over a stack of sieves, stones larger than a given opening stay on that screen while smaller ones fall through to the next finer screen. This creates uniform size fractions quickly, which is essential for pricing, matching for settings, and keeping lots consistent. Measuring each stone individually with calipers would be impractical for thousands of pieces, and scales only weigh stones (not their actual diameter), while pipes aren’t a method used for size sorting.
