We’ll cover essential considerations to ensure you get the best value when investing in a 4-carat oval diamond.
4-Carat Oval Diamonds Price Range
The price of 4-carat oval diamonds can vary significantly based on several factors, primarily the 4Cs: cut, color, clarity, and carat weight.
On average, prices for these diamonds typically range from $25,000 to $180,000+.
At the lower end of the spectrum, you might find 4-carat oval diamonds with lower color grades (K-M) and clarity grades (SI1-I1) priced around $25,000 to $45,000.
Mid-range options with better color (G-J) and clarity (VS1-SI2) can cost between $45,000 and $90,000. Premium 4-carat oval diamonds with excellent cut, high color grades (D-F), and top clarity ratings (IF-VVS2) can command prices from $90,000 to $180,000 or more.
Here’s a table illustrating approximate price ranges based on color and clarity for 4-carat oval diamonds:
| Color | Clarity | Price Range |

| I-J | SI1-SI2 | $55,000 – $90,000 |

Cut Quality
Cut quality is crucial when evaluating a 4-carat oval diamond, significantly impacting both its beauty and price. While oval diamonds don’t receive official cut grades like round brilliants, their cut quality still greatly affects their appearance and value.
For 4-carat oval diamonds, even small variations in cut quality can lead to substantial price differences. Well-cut ovals command premium prices, often 15-25% higher than those with less ideal proportions.
When assessing cut quality in oval diamonds, consider these factors:
- Length-to-width ratio: Typically, 1.35-1.50 is considered ideal, but personal preference plays a role.
- Symmetry: Ensures the diamond’s outline and facet arrangement are balanced.
- Polish: A smooth surface allows better light entry and reflection.
- Depth percentage: Ideally between 58-62% for optimal light performance.
- Table percentage: Typically 53-63% for balanced proportions.
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 oval diamonds. The color scale for white diamonds 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 oval diamonds:
- D-F (Colorless): Command the highest prices, often 25-40% 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 oval diamonds 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 oval 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 oval 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 oval 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 oval diamonds, consider that their elongated shape can sometimes make inclusions more noticeable than in round brilliants.
Carat weight
At 4 carats, oval 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 oval diamond pricing:
- Price jump: Expect a substantial price increase from 3 to 4 carats, often 25-40% or more.
- Rarity factor: 4-carat oval diamonds are less common, contributing to higher prices.
- Quality premium: Higher quality (cut, color, clarity) becomes more critical and expensive at this size.
Price comparison (approximate, for similar quality):
- 1-carat oval diamond: $4,000 – $15,000
- 2-carat oval diamond: $12,000 – $60,000
- 3-carat oval diamond: $24,000 – $120,000
- 4-carat oval diamond: $25,000 – $180,000+
This exponential price increase reflects the rarity and desirability of larger diamonds. When budgeting for a 4-carat oval diamond, consider that small compromises in color or clarity can lead to significant savings without necessarily impacting visual appeal.
