Definition of a Cut
Gemologists often consider the cut to be a diamond's most important characteristic. The cut has an overall influence on a diamond's beauty. What is generally known as a sparkle of a diamond is determined by the cut. Jos Alukkas' gemologists recommend that client select the highest cut grade possible within their budget as the cut is the most important parameter of a diamond's appearance.
A diamond's cut grade is a measure of the gem's light performance or sparkle. When a diamond is cut with the proper proportions, light is returned out of the top of the diamond (referred to as table). If the cut is too shallow, light leaks out of the bottom. If the cut is too deep it escapes from the sides.
Different Types of Cut Grades
Ideal cut:This cut represents nearly top 3% of diamond quality based on cut. It reflects nearly all the light that enters the diamond. It is considered an exquisite and rare cut.
Very good cut: Represents roughly the top 15% of diamond quality based on cut. Reflects nearly as much light as the ideal cut, but is sold at a lower price.
Good cut: Represents roughly the top 25% of diamond quality based on cut. Reflects most of the light that enters. Considered to be less expensive than a very good cut
Fair cut: Represents roughly the top 35% of diamond quality based on cut. Even though it is still a quality diamond, a fair cut will not be as brilliant as a good cut.
Poor cut: The poor cut grade includes diamonds, which are so deep and narrow or shallow and wide that they lose most of the light from the sides and bottom. Jos Alukkas does not offer diamonds with Poor Cut Grades.
