  • Type in your price/ct or total price (TTL)

The calculator automatically works out your price and displays the Rapaport List Price per carat and Rapaport Total Price

To see the best and Average Price for diamonds in this category:

  1. Click Avg/Best
  2. The screen displays
    - The average price on RapNet for that category of diamond: price/ct and Rap%
    - The best price on RapNet for that category of diamond: price/ct and Rap% ** see important note below


  • Best Price shown on the calculator and TradeScreen is the best price that meets Rap Spec A1, A2 and A3 and is GIA graded
  • This means that the price displayed is for the best cheapest stone on RapNet but not the cheapest stone overall
  • To find the BEST cheapest stone you can either fill in the parameters in the search engine as GIA and add the Specs or you can use the Trade Screen
