The number of Carats a diamond has refers to the stone’s weight. The main thing to take from here is that weight does not equal size. Each diamond carat weighs exactly 200 milligrams. Because a diamond is a 3-dimensional object, if you double the Carat weight you don not double the diamond's physical size. As you can see below the size of the diamond will increase at a proportionally slower pace as the Carat size is increased.
Carat Size Curve
Beyond the mathematical limitations of Carat size though, the Cut of the diamond can have an effect on how we perceive that weight. A poor Depth Percentage can make a diamond of a particular weight either look too small, or inversely too large. What’s the problem with a diamond looking too large? If the diamond is cut very wide, the reflective angle of the light will be too shallow. Thus, that .75 ct. diamond may have the table size of a 1 ct. diamond, but the shallow reflective angle will make it dull and lifeless. Similarly, when choosing between diamonds, a smaller carat stone can look larger because it was cut with the proper proportions as compared to a larger stone that was cut poorly.
The Carat weight of a diamond will never be a place where you can find a ton of value, as generally speaking people want the largest diamond possible. The goal is to compromise in Color and Clarity so we can find a wonderfully Cut diamond in the highest Carat possible. That’s why you should reach out to us, as we’ll make sure you keep your Cost down and get the best diamond possible!
