9. Diamond Fields and Values

The following table provides more information for some of the diamond fields in the Tracr Data Dictionary.

Field name
Description
Allowed values

cut_grade

The grade of cut.

I= Ideal, ID EX = Excellent, EXC VG = Very Good G = Good F = Fair P = Poor

colour

This field is auto-generated based on the defined colour of the diamond. It cannot be set via the API but will be returned in both the rough and polished data for any given diamond accessed via the API. For white diamonds the value will be the same as the defined colour (D-Z scale). For fancy coloured diamonds (those with at least fancy_colour and fancy_colour_intensity) the value will be a human readable representation of the diamonds fancy colour (e.g. Fancy Dark Greenish Blue).

Examples: White Diamond: D Fancy Colour: Fancy Dark Greenish Blue
