When it comes to finding the perfect engagement ring, carat size is one of the most important characteristics. The weight of a ring is one of its most distinguishing features, and it can dramatically impact its cost and overall look. So, if you're trying to narrow down the ideal ring size for your budget and style, it can be helpful to see different diamond carat sizes on a hand. Since an engagement ring often comes with a higher price tag, it's important to do your research ahead of time to ensure you're making the right decision. To help, we're taking the guesswork out of carat sizes. We've tapped jewelry experts to share everything you need to know about different diamond carat sizes, along with photos of diamond carat sizes on a finger to help make an educated choice.


Seeing diamond carat sizes on a hand is the best way to get an idea of the weight you like. To help you visualize different carat sizes, the photo below depicts seven-carat sizes on a hand. From left to right, the different carat sizes shown are 4 carats, 3.5 carats, 3 carats, 2.5 carats, 2 carats, 1.5 carats and 1 carat. A ring's setting can also affect the look of the diamond. Below, five round diamonds are shown on a size six finger in an open setting (meaning no prongs are securing them). From bottom to top, the different carat sizes shown are 4 carats, 3.5 carats, 3 carats, 2.5 carats and 2 carats.


When it comes to picking the right diamond carat size, budget is the most important consideration. If you're shopping within strict price parameters, avoid going over—it's better to buy in your price range than to start your engagement in debt. To make the most of your purchase, consider buying a carat size slightly under your preferred weight. For example, if you want to buy a 3-carat diamond engagement ring, a 2.75-carat diamond will look almost the same at a lower cost. Work with your jeweler or an expert to source a diamond-carat size that's right for your style and within your preferred price range.
