8/28/2023 0 Comments Diamond points to caratsPerhaps you’ve always dreamed of wearing a 2.0 or 3.0 carat diamond engagement ring. If you have your heart set on a larger carat weight, but still want to work within a particular budget, consider a diamond with an I or J color grade, and SI1-SI2 clarity. A larger carat weight diamond could also be made to appear smaller with a lower quality cut (Good, Fair and Poor). A diamond that has been cut well, with a grade Very Good or higher, will have more light reflected out the top of the stone, which will make it look larger. A higher cut grade will cause a smaller weight carat diamond to appear larger. When it comes to the value or price of a diamond, carat weight is only one factor in the equation.The other 4C’s come into play too (Cut, Clarity & Color) but interestingly, a diamond’s cut will impact how large the carat weight appears. This kind of precision is necessary in the diamond industry because even the smallest variation in carat weight can greatly impact the price of a diamond. You might see for example a diamond that is 1.17 ct, which would be described as ‘one point seventeen’ carats, or ‘one seventeen’. If a diamond’s weight is greater than one carat, it is described in carats and decimals because diamond weight is measured to the hundred thousandth of a carat and then rounded to a hundredth of a carat. If a diamond is 25 points, it weighs 0.25 carats. The modern metric carat is equal to 0.2 grams, and is the standard unit of weight for diamonds and other gemstones all around the world.Ī carat is divided into 100 points, just like a dollar is divided into 100 cents. Carob seeds were used in this manner because of their uniform weight, and the term ‘carat’ is taken from the word ‘carob’. The system of carat weight measurement for diamonds and gemstones originated with carob seeds being used by early gem traders as counterweights in their balance scales. Many people mistakenly believe that the term ‘carat’ refers to a diamond’s visual size, when it in fact refers to the weight of a diamond. A Straight-forward Guide to Understand Diamond WeightĬarat weight might be the most commonly misunderstood of all the “4 C’s” of diamond grading.
