On what basis are wholesale price lists typically organized?

Wholesale price lists for diamonds are typically organized based on specific combinations of the Four Cs: Cut, Color, Clarity, and Carat weight. This framework provides a standardized method of assessment that helps in evaluating the quality and value of a diamond. The Four Cs are critical to determining a diamond's market price, as they directly reflect its characteristics and overall appeal.

When wholesalers create price lists, they take into account how each of these factors interacts. For example, a diamond with a high grade in color and clarity but poor cut will generally be priced differently than one that is top-rated in both cut and clarity. The organization of price lists based on these criteria allows buyers and sellers to have a clear understanding of how individual diamonds compare to each other in value.

While market competition and demand do influence prices, they do not provide the structural basis for organizing wholesale price lists themselves. Geographic location may play a role in sourcing but is not a determinant for the prices listed. Similarly, focusing only on color and clarity neglects the importance of the other critical factors in diamond valuation.
