It takes time, care and a skilled hand to transform a raw stone into a brilliant diamond. The end result of such precise craftsmanship is the sparkling, show-stopping gem we all love. In turn, the value of a refined diamond is determined by four characteristics established by the Gemological Institute of America. These are known as cut, color, clarity and carat weight, otherwise known as the 4 C’s. Together, these variables determine the cost of a diamond and understanding each will guide you to the perfect sparkling piece.
The cut of your diamond is what makes it glamorous! Often confused with the shape, the cut dives deeper than just aesthetics to account for depth, symmetry and polish, which all determine how light radiates through the gemstone. When raw diamonds are mined, they start out unrefined and definitely not red-carpet ready. But, a well-cut diamond is able to catch light that glistens to make you the center of attention. Alternatively, a gemstone that’s cut too shallow or too deep will leave the stone looking small and dull. When a diamond has the perfect cut, it will shimmer and shine brilliantly.
Natural diamonds are formed when carbon, heat and pressure mingle deep in the earth to produce the glimmering gem that we can’t get enough of. The process can result in a variety of ‘inclusions’ and ‘blemishes’ that occur both inside and outside of the gem. These natural characteristics are a normal part of every diamond. However, a gem that has more inclusions and blemishes may appear cloudier, impacting its value. While no diamond is perfectly pure, the cleaner it appears, the more stunning (and costly) it will be.
Much like other precious gems, diamonds come in a variety of colors. While it’s forming, impurities in the earth determine whether the stone will be white and seemingly colorless or uniquely colored. Whatever your preference is, the lack of color will indicate the quality of your diamond. To set the cost, The GIA uses a scale to identify the grade. This chart ranges from D (colorless) to Z (light yellow or brown). Colorless diamonds are rare and in turn, more valuable.
Often confused with size, carat is actually the unit of measurement that determines a diamond’s weight. It’s quite rare for a large diamond to be found, so bigger, heavier stones tend to cost more than smaller ones.
However, carat weight alone doesn’t determine the ultimate cost of a diamond. The combination of the 4 C’s guides gemologists and jewelers to choose high-quality precious gems and provide you with show-stopping jewelry.
