Understanding the Cut of a Diamond

One of the misnomers about the “cut” of the diamond is that most people think that it refers to the shape. That’s not the case though. It actually refers to the diamond’s proportions, the diamond symmetry, and the ability of the diamond to unleash the brilliant sparkle for which they are so famous whenever light hits it. The cut is all about how the diamond interacts with light, and it is one of the most important elements to consider when buying a ring. A diamond with a great cut can actually be more impressive than a larger diamond with a poor cut. Most find the cut difficult to analyze, at least from a technical standpoint, especially when they are trying to evaluate the cut on different shaped diamonds. Experts will look for several things when they are trying to determine the quality of the cut on a diamond. They look for the brightness, sometimes called brilliance. This refers to the internal and external white light the diamond reflects. They also look at the “fire”, which is the way that the white light scatters and takes on various colors. Scintillation is the third thing that experts look for when examining the cut of a diamond. This is the amount of sparkle the diamond produces when a light source hits the diamond or the diamond moves in front of the light. The proportions of the diamond are very important when it comes to the cut. Each of the facets needs to be in the perfect place to be able to reflect the right amount of light, while letting the other light through. Even a slight miscalculation on the part of the expert cutting the diamond could cause the quality of the cut to diminish, and that would lower the value and desirability of the diamond. True experts who cut by hand take time and care to ensure that the cut is perfect. They take pride in their work and it shows. Knowing just how important the cut of the diamond is helps buyers. Even though they might not always be able to tell the difference, an expert eye can. Having an appraisal and a diamond report from the experts will give buyers an indication of the quality of the cut, and they will then have a better idea of whether they are getting a good deal on their diamond or not.
