RapSpecs, short for Rapaport Specifications, classify diamonds into different quality groups for easy reference and sorting.
They are for round-shaped laboratory-graded diamonds based on a combination of measurements, finish, and other physical diamond characteristics.
RapSpecs are A, B, or C and broken down further into divisions (e.g. A1, A2, A3)
All RapSpecs that start with a letter refer to GIA-graded diamonds only
Non-GIA grading reports also have RapSpecs, but they are less exact and on a different scale (1, 2, or 3) - see bottom of the page -
Much of the data that goes into the RapSpec calculation is gleaned from the diamond grading report, and some other data is from the owner of the diamond or our Rapaport Laboratory (for example brown shade)
Note: The Rapaport Price List is based on RapSpec A3 and better diamonds
