Ideal Cut Diamonds

The “Cut” plays a significant role in the four Cs of a diamond. It not only defines the basic facet arrangement but also affects its brilliance. The cut of a diamond can be classified based on how the light reflects from the stone and hence creating particular amount of brilliance from the diamond.

The different types of diamonds are:
Shallow Cut
Ideal Cut
Deep Cut

Among them, Ideal cut diamonds are mostly preferred since light reflects from the top of the stone hence creating maximum brilliance among all the types. Also, irrespective of the direction from where the light has entered into the stone, all the light gets reflected increasing the diamond’s brilliancy and radiating exquisite light. In shallow cut ones, the light refracts away from the bottom hence resulting the diamond to loose its brilliance and making the stone appear glassy and opaque whereas in deep cut diamonds refraction of light takes place from the sides making it dull and lifeless.

This categorization depends on the proportion in which the diamonds are cut. An Ideal Cut Diamond has the proportion as shown below:

These measurements differ for different gemological laboratories.

Different grading laboratories have assigned different names to the diamonds with Ideal cut like Superb Ideal Cut, American Ideal Cut and even Excellent Cut. GIA (Gemological Institute of America) refers to it as Excellent Cut diamonds.

Since producing such diamonds requires exact and precise measures, they usually cost more than other diamond cuts.
