Everything you need to know about diamond size and carat weight.
Diamond Sizes
Carat weight measures how much a diamond weighs. One carat equals 200 milligrams.
While carat weight is often used synonymously with size, it actually refers to weight rather than physical dimensions. A diamond’s visible size also depends on its cut proportions and shape, which is why two diamonds with the same carat weight can appear noticeably different. The difference is often even more pronounced with fancy shapes such as oval, pear, and radiant, which tend to have a larger surface area when viewed from above.
Carat weight and visible size are closely related, but they are not the same thing.
A well-cut diamond distributes its weight in a way that maximizes its surface area and light performance. Diamonds that are cut too deep may carry unnecessary weight in the bottom of the stone, making them appear smaller than they should for their carat weight.
This is why two diamonds with identical carat weights can look different when viewed side by side.
Carat weight has a significant influence on diamond pricing because larger, high-quality diamonds are much rarer.
Price does not increase evenly with each incremental change in weight. Diamonds that reach milestone sizes such as 1.00, 1.50, or 2.00 carats often command a premium because they are highly sought after.
For this reason, some clients choose diamonds just below these milestones (sometimes referred to as a “buy shy”), where the visual difference is minimal but the price difference can be substantial.
Lab diamonds make larger carat weights more attainable than natural diamonds. Because they can be produced more efficiently, many clients are able to choose a larger stone while maintaining a similar overall budget.
However, growing larger lab diamonds well requires more time and careful control of the growth process. As carat weight increases, maintaining high crystal quality becomes more challenging.
For this reason, carat weight should never be considered in isolation. A diamond’s cut quality, proportions, and overall make play an equally important role in how large and beautiful the stone appears.
