Diamond pricing is determined by carat weight, and broken down in half-carat increments. Therefore, assuming factors like cut and clarity are equal, a diamond weighing one carat will cost more than a diamond weighing slightly less than one carat. However, if the cut and clarity are not equal, it is possible that a diamond with a one-carat weight will cost less than a smaller diamond. For this reason, it is important to consider all of these factors, including the cut, color, clarity, and carat, when choosing a high quality diamond.
Many people believe that the carat weight is a measure of the diamond’s size, but that’s not exactly true. The carat weight is a measurement of the diamond’s weight. While its carat measurement indicates the weight of a diamond, its length and width measurements indicate the actual physical size, or how big the diamond will appear when viewed from above. Diamonds of the same carat weight can vary in size depending on how they are cut. For example, a one-carat round diamond could measure 5.9 mm in diameter, while another one-carat round diamond could be 6.5 mm wide. Both of these diamonds are the exact same weight, pleaase see our tutorial for further info.
The price of a diamond typically rises as the carat weight increases. If carat weight is the most important factor in your search, consider a diamond with a clarity grade of Slightly Included (SI1-SI3) and a color grade of Near Colorless (G-J). By choosing a slightly lower clarity and color grade, you can find a larger diamond within your budget.
