How do dealers typically sort melee diamonds?

Dealers typically sort melee diamonds by size using sieves, which allows them to categorize diamonds based on specific size ranges. This method is effective because sieves have different mesh sizes that can separate diamonds into uniform sizes needed for various jewelry designs and settings. The sorting process ensures that diamonds of similar dimensions are grouped together, making it easier for jewelers to select the right size for their pieces.

Sorting by weight, color grading, or clarity assessments are important aspects of evaluating diamonds but are less practical for melee, which are often small stones. Since melee diamonds are not typically graded for color or clarity in the same way as larger stones, size sorting becomes the most critical factor in their categorization before they are set into jewelry.
