Usually we use this term to indicate the shape the diamond is polished into, i.e., round cut, pear cut, oval cut, etc. The cut is actually one of the 4 C’s and can be rated as ‘Excellent, ‘Very Good’, ‘Good’, ‘Fair’ and ‘Poor’. This rating depends on how good the proportions, symmetry and polish of the diamond are. Proportions and symmetry are what influences the overall brilliance and fire of the stone, rather than just the shape. The shape however does influence in what way the diamond displays its fire and brilliance. A princess for example will shine in a very different way than a round brilliant.
