The cut will depend on the gemologist’s assessment of the rough diamond. The analysis is exhaustive. Three factors will determine the cut of the diamond: the brilliance (the amount of light the diamond reflects), the scintillation (this refers to flashes of light) and fire (the bounce of light inside the diamond creates a colour spectrum inside).
If the diamond is not cut to the appropriate depth and surface measurements, the depth of light could be lost, reducing its brilliance and thus, its value. The cut of a diamond must have the most perfect combination possible with regard to proportion, symmetry and shine.
Parts of the Diamond:
– Diameter: width of the diamond or middle of the girdle
– Table: upper face of the diamond and the most polished part.
– Crown: the section between the girdle and the table.
– Girdle: the section where the crown finishes and the pavilion starts. It is the widest part of the diamond.
– Pavilion: it starts at the girdle and finishes at the culet. It is the lower part of the diamond.
– Depth: full length of the diamond. It is measured from the crown to the culet.
The levels of cut range from excellent, very good, good and acceptable to poor, according to how the diamond reflects light.

Advice for choosing a diamond based on cut:
– It is important to view it in the light and observe how it reflects light inside it, creating a rainbow of colours.
– You are advised to ask the gemologist about the different cuts and forms available.
– Make sure you choose the perfect form for you, according to your tastes and requirements.
