Diamond Carat Weight
What is diamond carat weight?
Diamond carat weight is another often-misunderstood diamond characteristic. Diamond carat weight refers to the weight of a diamond and is often used as a measurement of its size. One carat is equivalent to 0.2 grams, and a diamond's weight is usually measured to the nearest hundredth of a carat.
Are larger diamond carat weights always better?
Bigger is not always better when it comes to diamond carat weight. Yes, traditionally a "big rock" has been a status symbol when it comes to jewelry, but larger carat weight does not directly relate to sparkle or brilliance. The radiance or sparkle of a diamond is mostly due to the cut of a diamond, not the carat weight. In fact, if you compared two diamonds side by side that had different carat weights (one larger and one smaller) but the smaller diamond had a better cut (say very good or excellent) then the smaller diamond will actually appear larger!
Are larger carat weight diamonds more expensive?
The short answer is, yes, but it is more accurate to say that carat weight has the biggest impact on price. There's several reasons for this, including the value we as consumers place on larger diamond carat weights, as well as the fact that larger diamond need to be cut from larger rough crystals which are harder to source (rarity and scarcity equals bigger price tag).
Diamond Carat Weight Buying Tips
1. Choose carat weight sizes slightly below whole and half carat weight numbers, such as 0.90 versus a 1.00 carat. This will shave a good chunk off the purchase price and you'll honestly never know the difference by looking at it.
2. If you value size, then try for a fancy shape diamond. Fancy shapes are generally less expensive than round diamonds when comparing carat to carat. In fact, some fancy shapes will actually appear larger than their carat weight due to the way they're cut.
3. Keep proportions in mind! The smaller the finger/ring size, the larger the diamond will look. A 1.00 carat diamond solitaire, for example, will look a lot larger on a size 3 finger versus a size 6. If your significant other has smaller fingers, then don't feel pressured to search out larger diamonds, focus on those other 4Cs.

Diamond carat weight is typically measured using highly precise scales that are designed specifically for weighing gemstones. These scales are able to measure carat weight to the nearest hundredth of a carat, or 0.01 carats. One carat is equal to 0.2 grams, or 200 milligrams.
It's important to note that carat weight is not the same as diamond size or diameter. A diamond with a higher carat weight may appear larger than a diamond with a lower carat weight, but other factors such as cut and shape can also affect how big a diamond looks.

For the untrained eye, it's extremely difficult to determine diamond carat weight just by looking at a diamond - especially since we know carat is based on weight not size.
To determine the carat weight of a diamond, you will need to use a diamond scale that is specifically designed for weighing gemstones. These scales are highly precise and are capable of measuring the weight of a diamond to the nearest hundredth of a carat (0.01 carats).
To weigh a diamond, you will need to follow these steps:
- Clean the diamond: Before weighing a diamond, it's important to make sure that it is clean and free from any dirt, oil, or residue that could affect its weight. You can use a soft cloth and a mild detergent solution to clean the diamond, being careful not to scratch or damage it.
- Prepare the scale: Turn on the diamond scale and make sure that it is properly calibrated. You should also make sure that the scale is set to measure in carats.
- Place the diamond on the scale: Using a pair of diamond tweezers, carefully place the diamond on the scale. Be sure to center the diamond on the platform to ensure an accurate reading.
- Record the weight: Once the diamond is on the scale, record the weight to the nearest hundredth of a carat (0.01 carats).

Diamond carat weight is a measure of the weight of a diamond, not its size. However, carat weight can be a good indicator of a diamond's size, as larger diamonds typically have a higher carat weight than smaller diamonds.

The carat weight that is "best" for an engagement ring depends on personal preference and budget. A larger diamond may be more impressive and eye-catching, but it may also be more expensive. Conversely, a smaller diamond may be more affordable, but it may not have the same visual impact as a larger diamond.
In general, the average carat weight for an engagement ring diamond in the United States is around 1 carat. However, the ideal carat weight for an engagement ring will vary depending on a number of factors, including personal taste, lifestyle, budget, and the engagement ring style (i.e. solitaire versus three-stone).
When choosing a diamond for an engagement ring, it's important to consider all of the 4Cs (carat weight, color, clarity, and cut) to find a diamond that fits your preferences and budget. It's also important to consider the style of the ring and how the diamond will look in the setting.
