The metric carat is the international standard unit of measurement of a diamond. One carat is equal to 200 milligrams, or 0.2 grams, and is divided into 100 points. As the size increases, so does the value per carat, which means the price rises exponentially with the size of the stone. If you have two diamonds that are identical in most respects—polish, carat weight, colour and clarity—one may look bigger or brighter than the other due to the cut and skill of the cutter, and the stones may have different values. A well-cut diamond will sparkle more and can look larger than its actual size; a poorly cut diamond may appear dull or glassy and have dark areas that indicate light is leaking out. Also, much of the weight of a poorly cut diamond may be “hidden” in its base, making the stone appear smaller than its actual carat weight.
What should I consider about carat weight in buying a diamond?
The jewellry professionals at BisouMargaux will help you achieve a balance between size and quality. If you prefer a larger piece and are working within a budget, we will take the time to look at 4C profiles with slight differences in colour and clarity grades to illustrate ways to obtain a quality, larger diamond within your budget.
A great sparkler does not always have to be a huge diamond!
The larger the diamond, the more challenging it is to make it a perfect cut. Apart from this, the jewellry design will affect how we select the carat of the diamond. If, for example, the piece will be diamond encrusted, even if the main jewel is of a smaller size, it can still provide the same shine. On the other hand, if the size of the diamond is large, a design that focuses only on the jewel can give a lasting impression. In terms of ring size, the length of fingers, and the palm size will affect the diamond visually too.
