Cut

One of the most defining characteristics of a diamond is its cut, since this is what gives a diamond its sparkle. While high grades of color, clarity, and carat weight also contribute to a diamond's price and appeal, it's the cut that determines the symmetry of the stone's facets, its overall proportions, and its ability to reflect light (aka the ‘bling-bling’ effect). 

Cut does not refer to shape (round, princess, oval, etc.) but the symmetry, proportioning and polish of a diamond. The cut of a diamond greatly impacts a diamond's shine or brilliance. This means if it is cut poorly, it will be less luminous.

Cut Grades:

 

Diamond Hedge Ideal cut: Represents roughly different companies' top 1% of diamond quality based on cut. The highest grades of polish and symmetry allow it to reflect even more light than the standard ideal cut.

 

Ideal cut (Excellent cut): Represents roughly the top 3% of diamond quality based on cut. Reflects nearly all light that enters the diamond.

 

Very good cut: Represents roughly the top 15% of diamond quality based on cut.  Reflects nearly as much light as the ideal cut, but for a lower price.

 

Good cut: Represents roughly the top 25% of diamond quality based on cut.  Reflects most light that enters. Much less expensive than a very good cut.

 

Fair cut: Represents roughly the top 35% of diamond quality based on cut.  Still a quality diamond, but a fair cut will not be as brilliant as a good cut.
