Understanding the cut of a diamond doesn’t need to be complicated. Whether you’re looking to buy a diamond for a pendant, pair of earrings or an engagement ring, this simple guide to diamond cut grades will help. There’s basically three main cuts of a diamond – The ideal cut, deep cut and shallow cut. As you may know, diamonds can be cut into many different shapes and sizes, but is very important when determining the quality of the stone. The better the cut, the more reflective qualities and the more sparkle the diamond will have.
The Three Cuts of a Diamond
To help explain the cuts visually and a lot more detailed, the arrows in the diagram below represent the amount of light that can reflect through the stone, to give it its ultimate sparkle and brilliance. Idea Cut Diamonds These diamonds have been cut to perfect, with exact proportions, and polished with a great amount of attention to detail. This cut is considered extremely valuable, as light passes through the top, hits both sides of the pavilion and reflects back through the top. Deep Cut Diamond Diamonds have more depth and will reflect much of the light to the opposite facet of the pavilion, which causes the light to reflect at the wrong angle. A deep cut may result in the diamond appearing darker in the centre. Shallow Cut Diamond If the cut of the diamond is too shallow, the light through the top will be lost through the bottom of the stone. To the naked eye the diamond will have less brilliance and appear duller then the ideal cut.
