Printable Diamond Colour Chart
This one-page Letter PDF is for anyone comparing diamond colour grades before a purchase, appraisal, or lesson. It shows the diamond colour scale from D to Z in three columns: Grade, Category, and Description. The rows include examples such as D, Colourless, Highest grade; no detectable colour; E, Colourless, minute traces detectable only by an expert; and F, Colourless, slight colour detectable only by an expert. It is based on the GIA scale and reminds you that diamond colour is judged in person.
