The carat weight of a stone is a direct indicator of its size; the more a diamond weighs, the larger it will be. Of course, the price of a diamond will increase as the carat weight increases. It’s important to understand it’s not a linear price increase: a 5-carat diamond won’t cost five times more than a 1-carat diamond; it could cost 100 times as much or more. When you’re shopping for a diamond you need to think about the curve of size versus price and think about where you want to be so you can stay in your budget while you trade off the other C’s.
