Quick Tips for Success
The Rapaport Price List updates every Thursday at 11:59 PM EST. Always ensure you are looking at the most recent list before finalizing a high-value deal on Friday morning.
In the Price Calculator, play with the +/-% Rap field. This helps you quickly see how a small shift in discount affects the total stone price without doing the manual math.
Before listing or buying a diamond, check TradeScreen. If your price is significantly higher than the "Average Price" listed, you may want to adjust your discount to increase conversion velocity.
