In evaluating carat size of moissanite versus diamond, other factors besides carat information provided with a piece of jewelry should be considered when evaluating appearance. Carats measure weight, but millimeters are a better measure of appearance.
Other important factors to consider include moissanite watches and other jewelry with moissanite set in the bezel, dial, case, and bracelet.
If you're deciding between a moissanite and diamond watch, look for other similarities and differences beyond carat weight. Differences in stone size and shape and watch design and placement will affect the overall look of the watch.
Other details may be useful when comparing moissanite and diamond watches to buy a watch style within your price range and with your preferred features.
Carat Weight and Gemstone Size Questions and Answers
Carat is a unit of weight used for gemstones. One carat weighs 200 milligrams. The carat is not a unit of measurement for size.
Two gemstones with the same carat weight may look like different sizes because of density and other factors related to gemstone cutting. Special considerations are involved when comparing moissanite and diamond.
Moissanite has a different density than diamond. As a result, a moissanite gemstone and a diamond gemstone that are the same size in other ways will have different carat weights. Some moissanite retailers provide consumers with Diamond Equivalent Weight (DEW) information to make it easier for them to compare moissanite to diamonds of comparable size.
These are important terms to know:
- Carat: Weight of a single gemstone.
- Actual Carat Weight (ACW): The weight of the gemstone.
- Diamond Equivalent Weight (DEW): Value given for moissanite stones to give customers an approximation of the size of a diamond the moissanite stone would resemble.
- Millimeter (mm): Physical dimensions of a stone, such as its diameter or length and width.
- Total Carat Weight (TCW): The combined carats of multiple gemstones mounted on a piece of jewelry or watch.
When purchasing jewelry, check with the seller to find out what measurements are provided. Jewelry rated for high total carat weight may have many small stones rather than a few larger stones.
Moissanite vs Diamond Size Comparison Table
A millimeter measurement is more useful than a carat measurement. This chart gives approximate face-up diameters for round brilliant diamonds. Use the chart as a guide when comparing moissanite diamonds of similar size.
|
Diamond carat weight |
Approximate diameter |
|
0.50 carat |
5.1 mm |
|
0.75 carat |
5.8 mm |
|
1.00 carat |
6.5 mm |
|
1.50 carat |
7.4 mm |
|
2.00 carats |
8.2 mm |
These measurements are approximate. Actual measurements vary depending on the cut, depth and proportions of the stone.
The chart does not indicate that all moissanites in a particular size range will have the same diameter as the diamonds shown in the chart. Moissanites and diamonds have different properties. Look for millimeter measurements on the seller's site to compare if possible.
For example, information about a watch might say that a stone is an equivalent weight to one diamond carat. Information about the size of the stone can be used to compare it to stones in other watches.
Weight information can complement other information about a stone, but it should not be used instead of the stone's physical dimensions.
What Does Carat Weight Mean for a Moissanite Watch?
Moissanite watch designs feature stones on multiple components, including the bezel and dial of the watch and the links and clasp of the watch bracelet. The total carat weight of a moissanite watch may include the weight of all watch stones.
This emphasizes the importance of understanding product specifications. Consider two watches with the same carat rating. One watch features a few large diamonds set in the bezel. The other watch features a number of smaller diamonds set in the band and bezel. These two watches may have the same carat rating, but they will appear different.
Look for these details before buying:
- Stone count: Number of moissanite stones used in the watch.
- Stone sizes: Are individual stones sized in millimeters?
- Stone placement: Are stones set in the bezel, dial, bracelet, or more than one location?
- Weight details: Details about the weight of jewelry in carats or diamond equivalent weight or total carat weight are provided.
- Cut and setting: Round or baguette stones? Other types? What type of setting?
If a watch listing includes only the total carat weight of watch gemstones but no other information about the gemstones, you can ask the seller for additional information. Additional information about watch gemstones can help you compare other features of similar watches to information in other listings.

Watch cost does not depend only on the precious stones used in the watch. Other factors influencing price include brand and other materials used in the watch, watch mechanism type, watchmaking methods, watch style, and quality of the stone setting.
Moissanite's colorful properties appeal to customers shopping for jeweled watches at lower prices than those with diamonds. Other considerations play a role in the quality of moissanite and other watches.
Additional features to consider when purchasing a moissanite or other jeweled watch include the materials used in the watch case and band, movement, bracelet construction and warranty details.

How to Choose the Size of a Moissanite Watch
The best size of moissanite to use in a watch is mainly a matter of personal preference. Multiple moissanite stones can enhance the appearance of a watch dial. Smaller moissanite stones can make a watch dial appear more balanced.
Think about these issues as you explore options.
1. Check the Watch Case Size
Think about the size and thickness of the case. Bigger cases can hold more gems. Bigger cases might not fit smaller wrists well. Smaller cases tend to look simpler and be more comfortable for everyday wear.
Compare the watch you plan to buy to other watches you already have. This may be a better method of assessing size than looking at pictures online.
2. Compare Measurements on Different Parts of a Stone
If the seller provides stone dimensions in millimeters, you can use these stone dimensions to make an educated guess about the size of the stone. Diameter is a useful size measurement for round stones. Length and width are both useful size measurements for baguette stones.
Don't assume that two watches with the same carat weight will appear the same. Variations in the types, shapes, and placement of gemstones will likely be apparent.
3. Look at Stone Placement
A moissanite bezel watch serves to highlight the watch dial. A full-iced-out watch features moissanites in both the watch case and band.
Search for watches with stoned bezels or dials and pavé-style bracelet links or other stone features. Images of the watch from multiple angles can help you see where stones are set on a watch.
4. Educate Yourself About the Cut and Type of Setting for the Gemstone
Round brilliant gemstones are designed to reflect light. Stepped cuts in baguette gemstones produce longer, clearer reflections.
The environment in which the stones are set may affect their appearance and security. View photos and ask the seller about the security of the stones, particularly if you intend to wear the watch frequently.
5. Review the Complete Specification
Research materials and other information about the watch's movement, water-resistance rating, and warranty and return policies before purchasing. Don't rely on a watch's looks or cost to determine water resistance.
Ask for additional information about gemstone and carat sizes if these details aren't included in the product listing. Complete product descriptions allow buyers to compare similar watches.

Frequently Asked Questions (FAQs):
Here are similar questions that people have searched for on Google about the same topic.
Will moissanite have the same size as diamond at the same carat weight?
Not necessarily. Moissanite and diamond have different densities. A moissanite and a diamond can weigh the same carat weight but not be the same size. To compare the sizes of moissanite and diamond, compare the millimeter sizes.
What does DEW mean on a moissanite watch?
DEW stands for Diamond Equivalent Weight and tells you how much a diamond of equal size to the moissanite would weigh. Check other information provided in the listing about the moissanite, including its weight and size.
Is a higher carat weight always better for a moissanite watch?
No. Additional carats do not automatically make a watch look larger or better. Other characteristics that affect a watch face's appearance are the number, size, and arrangement of gems.
Final Thoughts
When comparing the size of a moissanite carat to that of a diamond, there are multiple considerations. Carat weight is a useful measurement for comparing weights of gemstones, while millimeters can be used to compare the apparent size of gemstones. DEW is one tool for comparing gemstone sizes, but other factors should be considered in addition to DEW when purchasing gemstones.
In addition to other considerations, think about the number and variety of moissanites and where they are located on the watch case and bracelet when purchasing a moissanite watch. These details can be useful for comparing different watches and finding one that meets your other requirements and budget.
