The Importance of Buying a Diamond Carat

If you're looking to buy a good diamond ring, it can be overwhelming to try and figure out what size you should get. But the carat weight of your diamond is more important than its overall size when it comes to cost: The price of a diamond is determined by many factors but most importantly by its cut grade (which affects how light will reflect off it), color grade (how clear the stone looks), and clarity grade (how free from flaws).

What is a carat?

The carat is a unit of weight that indicates the weight of a diamond. A carat is 20 milligrams and the weight of one carat can be calculated by dividing 200 milligrams by 100. For example, if you have an 18-karat gold ring with 28 diamonds, it means that each of those diamonds weighs approximately 0.35 grams (which equals to 1/3 carats).

How does weight affect diamond prices?

When you see a diamond advertised in a newspaper or on the internet, it’s often listed by its carat weight. This is because diamonds are priced by carat, not by size. The larger the stone, the more expensive it will be; but if you want to know how much your diamond will cost before purchasing it (and we recommend that you do), then you need to figure out how many carats make up each stone.

The price of a diamond is directly related to carat size and cut quality. The more carats there are in your diamond ring or diamond necklace chain—and as long as those stones are of excellent quality and graded correctly—the higher-priced your piece will be.

Diamond carat and size chart for round diamonds.

The carat is the unit of weight used to measure diamonds. A 1 carat diamond is large, but a 0.5 carat diamond is small; the size of a diamond is measured in millimeters. The diameter of a round brilliant cut diamond ranges from 7 millimeters to 28 millimeters and larger; it’s rare for anyone to have one that big!

The size of your ring will depend on your preferences, but keep in mind that if you want people to know that you have an expensive ring on, you should choose something with at least 5 or 6 carats (or 200 milligrams). If it’s smaller than this, people might think that it’s fake or not worth much money because they can’t see how well-cut and polished the stone itself is even if it does reflect light well

When considering diamond carat, it's more important to look at the diamond cut and clarity instead of just size alone.

A diamond’s carat refers to its weight, while size refers to the diameter of the diamond. While many people believe that bigger is better, when considering diamond carat it’s more important to look at the quality of a stone than its size alone. This is because a high-quality cut can make even a small stone appear larger than it would otherwise appear if it were poorly cut.

While you may think that larger diamonds are better because they will be more expensive and therefore worth more value, this isn't always true. A smaller-sized diamond might actually have higher quality ratings than an overly large one because its proportions allow for greater brilliance and sparkle when compared with other stones of similar sizes but lower grades and clarity levels.

Final Thoughts

You can see how carat weight affects the price of your diamond, but it's important to remember that it’s not the only factor. The cut and clarity of a diamond are also crucial. If you want to know more about these aspects, our blog has an excellent article on them here.
