Colour

Colour is graded by comparison to masterstones under standardized artificial light, equivalent to northern daylight. Indicated colours are only meant to show the difference in shades. D E F G H I J K L M N-O P-R S-Z

Clarity

A diamond is ”loupe clean or internally flawless” if, after examination by an experienced grader with a loupe 10 x under normal light conditions, it has been found free of internal characteristics. The other clarity grades are determined by the size, position, brightness and number of internal characteristics.

External characteristics and structure phenomena can be mentioned under ”identification marks” or ”comments”. The lowest clarity grades on the scale (indicated by p for piqué) refer to inclusions that can be seen by an experienced grader with the naked eye. LC/IF VVS1 VVS2 VS1 VS2 SI1 SI2 P1 P2 P3
