Diamond Guide

The Diamond Grading demonstrations on this page are for illustration purposes and should only be used as an educational guide. Any representation of diamond colour, sizing, clarity should be used as a rough guide, this is due to differences in monitors and monitor resolution settings.


The weight of a diamond is expressed in carats: 1.00ct = 0.2 gram.


Colour is graded by comparison to masterstones under standardized artificial light, equivalent to Northern daylight.

Temelli Jewellery predominently sources diamonds from a D-H colour range.
