At the lower end of the spectrum, you might find 4-carat radiant cut diamonds with lower color grades (K-M) and clarity grades (SI1-I1) priced around $20,000 to $40,000. Mid-range options with better color (G-J) and clarity (VS1-SI2) can cost between $40,000 and $80,000.

Here’s a table illustrating approximate price ranges based on color and clarity for 4-carat radiant cut diamonds:

| G-H | VS1-VS2 | $80,000-$100,000 |

| K-M | SI2-I1 | $20,000-$50,000 |
Cut Quality
Cut quality is paramount for radiant cut diamonds, significantly impacting both beauty and price. While radiant cuts don’t receive official cut grades like round brilliants, their cut quality greatly affects their appearance and value.
For 4-carat radiant cut diamonds, variations in cut quality can lead to substantial price differences. Well-cut radiant diamonds often command prices 15-25% higher than those with less ideal proportions.
When assessing cut quality in radiant cut diamonds, consider these factors:
1. Length-to-width ratio: Typically, 1.00-1.05 for square radiants or 1.20-1.30 for rectangular radiants.
2. Depth percentage: Ideally between 61-67% for optimal light performance.
3. Table percentage: Typically 61-69% for balanced proportions.
4. Symmetry: Ensures the diamond’s facets and overall shape are balanced.
5. Polish: A smooth surface allows better light entry and reflection.
Investing in a high-quality cut can significantly enhance the diamond’s appearance, making it appear larger and more brilliant than lower-quality cuts of the same carat weight.
Color
Color grading plays a crucial role in determining the price of 4-carat radiant cut diamonds. The color scale ranges from D (colorless) to Z (light yellow or brown), with D being the most valuable.
In 4-carat diamonds, color differences become more noticeable due to the larger size, making higher color grades particularly desirable. This visibility factor often leads to steeper price increases between color grades compared to smaller diamonds.
Price implications of color grades for 4-carat radiant cut diamonds:
– D-F (Colorless): Command the highest prices, often 20-35% more than G-H diamonds.
– G-H (Near Colorless): Offer a balance of quality and value, popular for larger diamonds.
– I-J: Present noticeable warmth, with prices 15-25% lower than G-H.
– K-M: Show visible yellow tints, priced significantly lower, often 30-40% less than G-H.
When selecting a color grade, consider that radiant cuts tend to retain color more than round brilliants. This characteristic may make it worthwhile to invest in a higher color grade for a 4-carat radiant cut diamond.
Clarity
Clarity refers to the presence of internal (inclusions) or external (blemishes) imperfections in a diamond. The clarity scale ranges from Flawless (FL) to Included (I3), with higher grades commanding higher prices.
For 4-carat radiant cut diamonds, clarity becomes increasingly important due to the larger size, which can make inclusions more visible. This visibility factor often results in more pronounced price differences between clarity grades compared to smaller diamonds.
Clarity grade impact on 4-carat radiant cut diamond prices:
– FL-VVS2: Premium prices, often 15-25% higher than VS1-VS2 grades.
– VS1-VS2: Popular choices, balancing clarity and value.
– SI1-SI2: Can offer significant savings (15-30% less than VS grades) if inclusions are not eye-visible.
– I1-I3: Substantially lower prices, but inclusions may affect brilliance and durability.
When evaluating clarity in radiant cut diamonds, consider that their facet pattern can help mask some inclusions. However, due to the larger size, it’s often recommended to choose VS2 or higher clarity grades for 4-carat radiant cut diamonds to ensure eye-cleanliness.
Carat Weight
At 4 carats, radiant cut diamonds are significantly larger than average and command premium prices. The price per carat increases exponentially with size, making 4-carat diamonds disproportionately more expensive than smaller stones of similar quality.
Key points about 4-carat radiant cut diamond pricing:
1. Price jump: Expect a substantial price increase from 3 to 4 carats, often 25-40% or more.
2. Rarity factor: 4-carat radiant cut diamonds are less common, contributing to higher prices.
3. Quality premium: Higher quality (cut, color, clarity) becomes more critical and expensive at this size.
Price comparison (approximate, for similar quality):
– 1-carat radiant cut diamond: $3,000 – $10,000
– 2-carat radiant cut diamond: $8,000 – $40,000
– 3-carat radiant cut diamond: $15,000 – $80,000
– 4-carat radiant cut diamond: $20,000 – $140,000+
This exponential price increase reflects the rarity and desirability of larger diamonds. When budgeting for a 4-carat radiant cut diamond, consider that small compromises in color or clarity can lead to significant savings without necessarily impacting visual appeal.
Why Should You Buy 4-Carat Radiant Cut Diamond?
Investing in a 4-carat radiant cut diamond offers several compelling advantages. The radiant cut combines the brilliance of a round cut with the geometric appeal of an emerald cut, creating a unique and captivating appearance. At 4 carats, this diamond shape makes a bold statement, standing out in any setting. The larger size allows the intricate faceting pattern of the radiant cut to truly shine, maximizing the diamond’s fire and scintillation.
From a practical standpoint, radiant cuts often appear larger than their actual carat weight due to their shape and faceting, providing excellent value for size. They’re also versatile, suiting various jewelry styles from classic to contemporary. The durability of the radiant cut, with its trimmed corners, makes it suitable for everyday wear, reducing the risk of chipping compared to shapes with sharp corners.
Additionally, 4-carat radiant cut diamonds are less common than some other shapes, offering a sense of uniqueness and exclusivity. This rarity can contribute to their value retention over time, potentially making them a sound investment. However, it’s important to consider the higher cost and to carefully evaluate the diamond’s qualities before making such a substantial purchase.

Evaluate the length-to-width ratio to choose between square or rectangular shapes based on your preference. Pay close attention to color, as radiant cuts tend to show color more readily than some other shapes. For clarity, aim for VS2 or higher to ensure eye-cleanliness in this larger size.
Verify certification from reputable grading labs like GIA or AGS to ensure accuracy of quality claims. Examine for fluorescence, as strong fluorescence can affect price and appearance. Compare prices from multiple reputable dealers to ensure competitive pricing. When possible, view the diamond in person or through high-quality imaging to assess its visual appeal.
Consider the setting carefully, choosing one that complements and secures the large stone effectively. Given the high value of 4-carat radiant cut diamonds, there may be room for price negotiation, especially with independent jewelers.

Factor in the cost of insurance for this valuable item. Think long-term about how the diamond will fit your lifestyle and if it’s a piece you’ll cherish for years to come.

A 4-carat radiant cut diamond makes a stunning centerpiece for an engagement ring, offering a perfect blend of size, brilliance, and modern elegance. The price of such a ring can vary significantly, typically ranging from $25,000 to $150,000 or more, depending on the diamond’s quality and the setting.
Setting Styles and Their Price Impact
Solitaire settings are often the most affordable, adding $500 to $2,000 to the diamond’s cost. Halo settings, which enhance the diamond’s perceived size, can increase the price by $2,000 to $5,000. Three-stone settings are typically the most expensive, potentially adding $5,000 to $20,000 or more, depending on the size and quality of the side stones.
For example:
- A 4-carat radiant cut diamond (G color, VS2 clarity) in a simple platinum solitaire setting might cost around $85,000.
- The same diamond in a halo setting could reach $90,000.
- In a three-stone setting with significant side diamonds, the price could exceed $100,000.
Practicality Considerations and Their Cost
Secure settings that protect the diamond’s corners, such as bezel or six-prong settings, may add $1,000 to $3,000 to the ring’s price. However, this additional cost can be a wise investment, potentially saving money on future repairs or replacements.
Complementary Band Designs and Pricing
Simple bands are the most economical, typically adding $500 to $1,500 to the ring’s price. Pavé bands can increase the cost by $1,500 to $5,000, depending on the quality and number of small diamonds used. Custom-designed bands with intricate details or additional gemstones can add $5,000 or more to the total price.
The diamond itself will be the most significant factor in the ring’s overall price. For a 4-carat radiant cut:
- A lower-quality diamond (I color, SI1 clarity) might start around $40,000.
- A mid-range diamond (G color, VS2 clarity) could cost about $80,000.
- A high-quality diamond (D color, VVS1 clarity) might exceed $140,000.
These prices are for the diamond alone, not including the setting.
