A diamond's ranking is calculated based on groups of similarly attributed diamonds called Pricing Groups.
Rapaport Trade defines pricing groups by default, using a carat range and then matches the shape, color, clarity, Lab, cut, polish and symmetry and fluorescence.
You can customize your own groups by customizing the pricing group and defining the flexiblity of the diamond's properties.
