Understanding Diamond Cut: The 4Cs of Diamonds

What is Diamond Cut

The cut of a diamond refers to how well the diamond’s facets interact with light, the proportions of the diamond, and the overall finish of the diamond.

It is not to be confused with the shape, (like emerald or round,) or facet arrangement, (like brilliant, or step cut), but is instead a reference to the craftsmanship of the diamond and how it factors into the diamond’s brilliance.

The Bottom Line

Keep in mind that a well-cut diamond will have more life and sparkle than one with a lesser cut quality. In fact, it can even appear to have a better face-up color or clarity!

And, if you compare a well-cut small diamond side by side with a slightly larger diamond of lesser cut quality, the smaller diamond may look larger to the naked eye.

Overall, it’s important to have your diamonds graded by a credentialed expert or a reputable diamond grading laboratory.
