The Argyle Grading Method

It shouldn’t come as too much of a surprise that the Argyle mine, which has managed to become the leading name in pink diamonds as a result of their brilliant branding as well as their incredible products, is responsible for creating a diamond grading system of their own.

The Argyle colour grading system is separated into three hues, with the descriptors as follows:

PP – Purplish Pink which is pink with a purplish secondary colour, and in rare instances Purple Pink where the pink and purple are in equal balance.

P – Pink which is straight, pure pink, and

PR – ‘Pink Rose’ which is a ‘rosey’ blush pink

The three hues are further divided into nine intensities utilising the prefix of 1 to 9; 1 being the deepest and 9 being the lightest.

In addition to this the Pink Champagne (PC) colour profile covers those diamonds with a brown body colour and a pink secondary colour. The intensity nomenclature is reversed for this colour range, PC1 being the lightest intensity through to PC3 being the darkest.
