Cut versus color

The diamond cutter must choose the most suitable size according the shape of the rough. With this intention, it must not only take elements such as the beauty, but also the "Yield", it ranges in general between 40 and 60%, normally we loss approximately 50% of the rough. For the fancy shapes the  rough stones loss is less; one can recover up to 80% for example for the emerald shape. These choice are  difficult, because a diamond with a excellent grade of the quality cut or very good will be worth expensive than a bigger diamond with a medim or fair quality of cut.The diamond cutter must choose the most suitable size according the shape of the rough.
