It’s important to note that the exact dimensions of a diamond can vary based on its shape and cut. For a round brilliant cut diamond, which is the most popular shape for engagement rings, a 4.5 carat diamond would usually have a diameter of around 10.3mm. Other shapes, such as princess cut or emerald cut, may have slightly different dimensions for the same carat weight.
