Your Biggest Questions About 1 Carat Diamonds, Answered
The 1 carat diamond is like the little black dress of engagement rings: Superpopular, a kind of style shorthand. As long as you shop smart, you can't go wrong. Market research has found that the average engagement ring size is just about that size, and that's where we recommend starting your search. But there are some important things to know about single carat diamonds — like, what's a carat? — so you can make the best possible decision for your loved one. Here are the essential things to know about 1 carat diamonds.
How big is a 1 carat diamond?
The carat is the standard unit of measurement for diamonds. Although most people think of a carat as a size, it's actually a weight. One carat is equivalent to 0.2 grams. A 1 carat diamond is about 0.6mm. A 2 carat diamond is approximately 0.8mm.
Fun fact: It typically takes about 250 tons of rock mining to produce just 1 carat of diamond.
Are all 1 carat diamonds the same size?
No. Some shapes appear bigger, and their mm measurements will be different.
Stones also carry their weight differently based on how they're cut, so two 1 carat diamonds of the same shape can have different table sizes. That's because of cut proportions. A deeply cut diamond holds a larger percentage of weight in its depth, so it will have a smaller diameter than a well-cut diamond. A well-cut diamond may have a lower carat weight than a deeply cut diamond, yet still have a larger diameter. A round stone that weighs as much as a princess cut diamond sacrificed more of its rough diamond formation to become a finished engagement ring. (If that all seems confusing, fear not. We have expert gemologists on staff to help you through these details to find the best diamond for you and your budget.)
How much is a 1 carat diamond worth?
It depends! The average retail price of a 1-carat ring is about $1,200, but it can vary depending on where you live and where you're looking. It also depends on the 4Cs of the diamond you're choosing. Remember, carat is only one of the four Cs you should consider when selecting a ring — clarity, cut and color are also important characteristics of a quality diamond. Two diamonds of equal carat weight can have very different price tags, depending on that cut, color and clarity.

How can I save money on a 1 carat diamond?
Here’s the thing about diamonds: there are breaking points in the measurements at which the price climbs, and steeply. These breaking points are typical around the rounder numbers of carat and half sizes. Think 1 carat diamonds, 1.5 carat diamonds, 2 carat diamonds, and on up. So if you’re willing to let go of the idea of having a number perfect 1 carat diamond, you can actually save a good deal of money. Diamonds that clock in just under these measurements, like a 0.95 carat diamond, are often cheaper — and no average person will be able to tell the difference on your engagement ring. Here are some other ways to save money if you don’t mind getting a number a little off that 1 carat mark:
- Buy just under breaking points, like a 0.96 carat diamond
- Buy under 1 carat and choose a halo engagement ring setting
- Choose a three stone setting to add extra size
If you have your heart set on that 1 carat diamond, we get it. There are still ways for you to save money on your center stone, too. Here are a couple that can cut down costs without giving up that number you love:
- Choose a diamond with a lower color grade, such as an H color diamond
- Choose a diamond with fluorescence, which GIA attests has no impact on sparkle but can bring down the cost of the stone
- Choose a diamond shape that uses more of the rough material (more waste, like with the round cut, means the price goes up)
