Proportion
An Ideal cut contains a specific set of tips process the proportions that provides a diamond the very best level of fireplace and brilliance. It takes under consideration the link between the table size, crown angle, tent angle, girdle, crown depth and tent depth. It evaluates the following:
the size of the table (flat surface) relative to the stone’s breadth at its widest purpose, referred to as the girdle
the angles of all aspects relative to 1 another
the depth of the crown vs. the tent and the way well the aspects at the crown (top) align with the tent (bottom)

Symmetry
Grading reports additionally rate the symmetry of the diamond’s aspects and the way well side edges align with one another, however corresponding aspects from opposite sides of the diamond align with one another and therefore the relationship between crown aspects and tent aspects.
Fluorescence
When exposed to ultraviolet illumination, atiny low proportion of diamonds glow, or emit a blue or traffic light. visible light is caused by trace parts, typically atomic number 5, that course into the diamond once it\'s created. whereas visible light doesn\'t essentially have an effect on a diamond’s price, it\'s listed on a diamond grading report.
