Diamond Carat Vs. Diamond Size
There is often confusion between diamond carat and diamond size, as they are mistakenly used interchangeably. However, it’s important to understand that diamond carat refers to the weight of the diamond, while diamond size refers to the physical dimensions and how large the stone appears.
It’s worth noting that a larger diamond size doesn’t necessarily mean it has a higher carat weight. Factors such as depth, table, and other shape features are independent of carat weight. The overall appearance and size of a diamond are influenced by its shape and how it is cut, including aspects like surface area and depth.
To find the perfect diamond for your preferences, it is important to consider various factors such as shape, carat weight, and overall size. In this article, we will specifically discuss 4-carat diamonds and explore the key aspects to keep in mind when considering a diamond of this size.
How Big Is A 4-Carat Diamond?
A 4-carat diamond typically has a size of approximately 10.1mm (0.4 inches) in diameter when it is a round brilliant cut. However, it’s important to note that the size can vary for different diamond shapes due to variations in shape and the length-to-width ratio.
It’s worth considering that factors like the diamond’s depth and table can affect the precise measurements of the stone.
4-Carat Diamond Ring Shapes
You can find stunning 4-carat diamonds in various shapes, allowing you to choose based on your personal style and preference.
If you prioritize a larger appearance, it’s worth considering the surface area variations among different diamond shapes. Depending on the size of the diamond’s table (top surface), one shape may appear larger than another.
The chart provided below illustrates the surface areas for each shape of a 4-carat diamond:
| Diamond Shape | Approximate Table Surface Area |
|---|---|
| Round brilliant-cut diamond | 10.32×10.32×6.22 mm |
| Princess cut diamond | 8.75×8.75×6.3 mm |
| Emerald cut diamond | 10.61×7.86×5.11 mm |
| Radiant cut diamond | 9.17×9.17×5.87 mm |
| Asscher cut diamond | 8.91×8.91×5.79 mm |
| Oval-shaped diamond | 12.89×8.59×5.24 mm |
| Pear shaped diamond | 14.36×8.65×5.28 mm |
| Heart shaped diamond | 10.42×10.42×6.25 mm |
| Marquise cut diamond | 16.48×10.42×6.25 mm |
| Trillion cut diamond | 12.28×12.28×4.91 mm |
4-Carat Diamond Ring Colors
Diamond color is graded on the GIA scale from D to Z. A D color grade represents the clearest diamonds, while a Z color grade indicates stones with noticeable yellow or brown tints.
Although there are slight differences between each color grade, most people find it challenging to distinguish one grade from another. However, the price difference between grades can be significant.
To ensure the diamond appears colorless, we recommend personally examining the diamond. What you see with your own eyes is more important than the assigned color grade.
You can closely inspect diamonds, even online through advanced photography, or seek assistance from a diamond expert to assess a diamond’s color.
Additionally, make sure the diamond appears white when compared to the color of the ring setting. Whether you choose yellow gold, rose gold, white gold, or platinum, a colorless diamond will appear white in any setting.
However, diamonds with grades of K or lower may appear white only when set in darker ring settings like yellow or rose gold. While these diamonds have a noticeable tint, the contrast with darker jewelry enhances their clarity and radiance.
For 4-carat diamonds, we recommend gems in the nearly colorless range of G to I. These diamonds appear white to the naked eye and generally come at a lower cost than those in the higher color range.
Keep in mind that a diamond’s cut is the most critical factor in its appearance. With an exceptionally well-cut diamond, it becomes harder to perceive color. Therefore, we advise placing more emphasis on the diamond’s cut rather than its color, regardless of the carat weight.
Clarity Rating For 4-Carat Diamond Rings
As you are aware, the diamond’s 4C’s have a significant impact on its beauty and brilliance. Clarity, in particular, refers to the presence of blemishes, inclusions, and surface defects within the stone.
The Gemological Institute of America (GIA) uses the following clarity grades:
- IF (Internally Flawless)
- VVS1 (Very, Very Slightly Included 1)
- VVS2 (Very, Very Slightly Included 2)
- VS1 (Very Slightly Included 1)
- VS2 (Very Slightly Included 2)
- SI1 (Slightly Included 1)
- SI2 (Slightly Included 2)
- I1 (Included 1)
- I2 (Included 2)
While it is important to consider the GIA clarity grading, it is also recommended to visually inspect the diamond yourself to determine if any inclusions or blemishes are visible to the naked eye. Seeking the assistance of an expert can help you avoid overspending on a factor that may go unnoticed.
The differences between two clarity grades, such as IF and VVS1, are extremely difficult to detect without magnification, despite the significant difference in price. An eye-clean diamond with a lower clarity grade will appear almost identical to a flawless diamond, assuming all other factors are equal. The main difference will be reflected in the price.
For 4-carat diamonds, we generally recommend a minimum clarity grade of VS2. At this grade, most blemishes and inclusions are invisible to the naked eye. In some cases, you may even find an SI1 diamond with inclusions near the edges, which can be hidden once the stone is set in its mounting.
To stay within a reasonable price range while considering clarity, we typically recommend a maximum grade of VVS2. At this grade, no inclusions or blemishes will be discernible to the naked eye. The goal is to find an eye-clean diamond. If you feel uncertain in this area, do not hesitate to seek the assistance of a diamond expert.
Price Of A 4-Carat Diamond Ring
The price of a 4-carat diamond ring can vary significantly, typically ranging from $30,000 to upwards of $250,000, depending on factors such as the diamond’s cut quality, color, and clarity.
In general, higher quality diamonds command higher prices. As we have explained in our guide to the diamond 4Cs, a diamond’s carat weight is just one aspect that influences its price, alongside cut quality, color, and clarity.
These factors play a substantial role in determining the price, particularly when dealing with larger stones like a 4-carat diamond. This is because aspects such as cut, clarity, and color become more noticeable in larger carat weights compared to smaller ones.
For example, a 4-carat round diamond with VS1 clarity and J color may cost approximately $47,000. Meanwhile, a diamond with identical cut quality, similar carat weight, but one clarity grade lower, could cost around $104,700. At the highest clarity and color grades, a 4-carat diamond can be valued at approximately $250,000 or more.
In summary, the price of a 4-carat diamond is determined by the interplay of the three other Cs: color, clarity, and cut quality. We recommend considering diamonds within the G-I color range and VS1 or VS2 clarity range to achieve the best value.
Additionally, the shape of the 4-carat diamond can also influence its price. Certain diamond shapes may cost more per carat compared to others. For instance, a 4-carat round brilliant cut diamond with VS2 clarity and E color may cost around $104,700 or approximately $26,000 per carat. However, if you change the shape to a pear shape while keeping all other factors the same, the price may be around $82,300 or $20,400 per carat – demonstrating a significant difference in cost.
This price variation based on shape applies to other fancy shapes as well.
4-Carat Diamonds: Pricing Overview
In this discussion, we will delve into the technical aspects that determine the value of a 4-carat diamond. It’s important to note that when we refer to 4ct diamonds, we are referring to their weight and not their size.
To provide some context, 4 carats is equivalent to 0.8 grams or 800 milligrams. Keep in mind that diamond prices are typically quoted per carat. For example, if a 4.5-carat diamond has a price of $24,000 per carat, the total price would be $24,000 multiplied by 4.5, resulting in $108,000.
The price per carat of a diamond increases as the weight category increases. For instance, while a 3ct diamond may be priced at $12,000 per carat, a similar 4ct diamond might be priced at $16,000 per carat.
This exponential increase in diamond price per carat with weight is due to the higher value associated with a heavier diamond and the corresponding higher price per carat within the weight category.
It is crucial to pay attention to the weight category because prices per carat do not consistently increase as the weight of the diamond increases. Additionally, it’s worth noting that diamond prices are often influenced more by emotion than reason.
While it may seem tempting to search for a diamond that is slightly below a new weight category, such as a 3.90-3.99 carat diamond, the reality is that it may not offer significant advantages. The pursuit of an “almost 4ct diamond” or a 5ct diamond has become increasingly popular, leading to higher prices for those specific gems and minimizing potential cost savings.
We’re not suggesting that you cannot explore a 3.90-carat diamond, but we advise against actively seeking one out as it may limit your search options without actually resulting in significant savings.
If you require assistance with your search for a 4-carat diamond, consider consulting diamond experts. Their expertise can help ensure that your purchase is the best possible one.
Getting The Best Value For A 4-Carat Diamond Ring
To ensure that your 4-carat diamond is absolutely stunning, we recommend following these guidelines:
- Shape: Choose the diamond shape that appeals to you the most. Additionally, select a ring setting that enhances the appearance of the stone while providing stability.
- Cut: Opt for diamonds with an Excellent cut grade on the GIA scale. An exceptionally well-cut diamond maximizes its brilliance and fire, surpassing other factors in terms of impact.
- Color: Consider diamonds in the nearly colorless range, specifically from G to I. These stones will appear colorless to the naked eye and are more affordable compared to diamonds in the D to F color range.
- Clarity: Look for diamonds with either a VS1 or VS2 clarity grade. These clarity grades offer the best value as they have inclusions and blemishes that are undetectable to the naked eye.
By following these recommendations, you can ensure that your 4-carat diamond is not only visually captivating but also offers excellent value for its quality.
