HUE The Predominant Colour
Fancy Shaped Diamonds
With that said most fancy colour diamonds are fashioned in what is known as fancy shapes. It is rare for a fancy colour diamond to be fashioned as a round brilliant cut diamond due to the fact that diamonds of this shape tend to hide colour. It is also rare for diamonds larger then 10 carats to be fashioned as a round diamond regardless of the presence or lack of colour.
All the above shapes are considered to have a style of faceting that is called brilliant facets. The emerald cut and Asscher cut are the two styles that are called step cuts. Due to the optics of step cuts attaining maximum colour strength is difficult and as a result diamonds of this style with a strong colour is rare.
Fancy red is the most coveted colour and only a handful ever see the light of day. Less than 3% of all tender diamonds have received a Red GIA classification. While clarity and carat weight ordinarily impact on the value of white diamonds, these characteristics are less of a consideration in the value determination of Argyle pink diamonds, with the focus being on colour and cut.
