Ever wonder what gives a diamond its sparkle? The cut…the cut…and did we mention the cut?
Cut is widely considered to be the most important of the 4Cs, having
Cut, being the only aspect of a diamond controlled by man, expresses the diamond’s natural sparkle and has the biggest impact on your diamond’s appearance and quality. It’s a big deal. And that’s why we suggest you invest in a quality cut grade first and foremost. We’re not saying that carat, clarity and color are unimportant, but sacrificing sparkle for a larger diamond, or one that’s color can only be distinguished under magnification isn’t the best strategy.
But in spite of the importance of cut, there weren’t any standardized criteria for cut grading before the mid 20<sup>th</sup> century. When criteria were finally standardized, it included brightness, fire, scintillation, weight ratio, durability, polish and symmetry. A cutter who is working with a diamond rough is trying to maximize each of these to make the diamond more rare and valuable. Needless to say, it takes a master level of craftsmanship to achieve maximum sparkle.
So what’s best? A diamond cut with the ideal proportions for its shape. Think of it like this: The bottom of the diamond has facets, and those facets act like mirrors. When the facets are cut at the proper angles, light enters through the top of the diamond, bounces off the mirrors, and returns back to your eye in a full spectrum of color.
And the opposite is true for a poorly cut diamond with incongruous proportions. It will allow light to escape out the bottom and sides, resulting in a dull, dark appearance.
In short, the angles allow the diamond to capture and reflect light or sparkle. For a really brilliant diamond, with excellent polish and symmetry, you should choose a cut grade of Very Good or Ideal. And finally, perfection in cut will also increase your diamond’s value, making it, so to speak, a cut above the rest.
