How to cut diamonds, and what is diamond cut? Knowing how diamonds are cut will help you make an informed choice when you make your next jewelry purchase. A diamond’s cut is sometimes known as its ‘make’, and is evaluated by examining the proportioning and finish of the diamond. These two factors contribute directly to the diamond’s fire and brilliance Fire refers to the colors that flash from within, while brilliance refers to the liveliness and sparkle of the diamond.

Diamonds are often cut to make them appear larger. And the more skilled the cutting, the more durable the diamond will be, as cutting faults can weaken the stone and make it susceptible to chipping.



How diamonds are cut

So how to cut diamonds well? Regardless of the shape chosen, a well cut stone will command a high premium. Diamond proportioning is very important, as it determines the aesthetic appeal of the stone. On a well-proportioned stone, the top portion (crown) generally appears to be one-third of the pavilion depth.

Ideal diamond cut

In the art of diamond cutting, the ‘ideal’ diamond cut refers to the cut that best exhibits the diamond’s personality. Again, the two main factors are fire and brilliance. In an ideally proportioned diamond, light is reflected from facet to facet and reflects out from the top, thus revealing maximum fire and brilliance.

But if the diamond is cut too deep, much of the light will be lost through the sides, thus causing the diamond to appeal dark in the center. And if the diamond is cut too shallow (sometimes to make it look larger), the reflection is dulled and the diamond loses brilliance. Thus the skilled metalsmith knows how to cut diamonds with exactly the right proportions.

The Tolkowsky cut has provided the basis for the ideal cut, and reflects a specific combination of angles that would create reflections that create the most fire and brilliance. Nonetheless, other variations have emerged, such as ‘EightStar’ and ‘Hearts on Fire’.
