4-carat emerald cut diamonds offer impressive size and sophisticated elegance, but their prices can vary widely.

This guide examines the key factors influencing the cost of these step-cut gems, helping you make an informed purchase. 

We’ll cover essential considerations to ensure you get the best value when investing in a 4-carat emerald cut diamond.

Price Range for 4 Emerald Cut Diamonds

The price of 4-carat emerald cut 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 $18,000 to $140,000 or more.

At the lower end of the spectrum, you might find 4-carat emerald cut diamonds with lower color grades (K-M) and clarity grades (SI1-I1) priced around $18,000 to $35,000.

Mid-range options with better color (G-J) and clarity (VS1-SI2) can cost between $35,000 and $75,000.

Premium 4-carat emerald cut diamonds with excellent cut, high color grades (D-F), and top clarity ratings (IF-VVS2) can command prices from $75,000 to $140,000 or more.

Here’s a table shows the price ranges based on color and clarity for 4-carat emerald cut diamonds:

ColorClarityPrice Range

I-JSI1-SI2$45,000 – $75,000
K-MSI2-I1$18,000 – $45,000

Note that these are general ranges, and actual prices can vary based on the specific characteristics of each diamond and market conditions.

Cut Quality

Cut quality is paramount when evaluating a 4-carat emerald cut diamond, significantly impacting both its beauty and price. While emerald cut diamonds don’t receive official cut grades like round brilliants, their cut quality greatly affects their appearance and value.

For 4-carat emerald cut diamonds, even small variations in cut quality can lead to substantial price differences. Well-cut emerald diamonds command premium prices, often 15-25% higher than those with less ideal proportions.

When assessing cut quality in emerald cut diamonds, consider these factors:

  1. Length-to-width ratio: Typically, 1.30-1.50 is considered ideal, but personal preference plays a role.
  2. Table percentage: Ideally between 60-70% for optimal light performance.
  3. Depth percentage: Typically 60-70% 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 grading plays a crucial role in determining the price of 4-carat emerald cut 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 emerald 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 emerald cut diamonds tend to show color more readily than other cuts due to their large, open table. This characteristic may make it worthwhile to invest in a higher color grade for a 4-carat emerald cut diamond.


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 emerald-cut diamonds, clarity becomes increasingly important due to the larger size and step-cut facets, 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 emerald 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 emerald-cut diamonds, consider that their step-cut facets and large table make inclusions more noticeable than in brilliant-cut diamonds. For this reason, it’s often recommended to prioritize higher clarity grades for emerald cuts, particularly in larger carat weights like 4 carats.

Carat weight

At 4 carats, emerald-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 emerald 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 emerald 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:

  • 1-carat emerald cut diamond: $3,000 – $10,000
  • 2-carat emerald cut diamond: $8,000 – $40,000
  • 3-carat emerald cut diamond: $15,000 – $80,000
  • 4-carat emerald cut diamond: $18,000 – $140,000+

This exponential price increase reflects the rarity and desirability of larger diamonds. When budgeting for a 4-carat emerald cut diamond, consider that small compromises in color or clarity can lead to significant savings without necessarily impacting visual appeal.

Buying Tips for 4-Carat Emerald Cut Diamonds

  2. Evaluate the length-to-width ratio: Choose a ratio that appeals to your taste (typically 1.30-1.50).
  3. Scrutinize clarity: Due to the step-cut facets, aim for higher clarity grades (VS2 or above) to ensure eye cleanliness.
  4. Consider color carefully: Emerald cuts show color more readily; opt for higher color grades if the budget allows.
  5. Verify certification: Insist on reputable grading reports (GIA or AGS) to ensure the accuracy of quality claims.
  6. Examine for fluorescence: Strong fluorescence can affect price and appearance; consider its impact carefully.
  7. Compare prices: Shop from multiple reputable dealers to ensure competitive pricing.
  8. Assess in person if possible: The unique characteristics of emerald cuts are best evaluated in person.
  9. Check for windowing: Ensure the diamond doesn’t have a see-through effect when viewed from the top.
  10. Consider the setting: Choose a setting that complements and secures the large stone effectively.
  11. Negotiate: Given the high value, there may be room for price negotiation, especially with independent jewelers.
  12. Understand return policies: Ensure the seller offers a reasonable return period for such a significant purchase.

  14. Think long-term: Consider how the diamond will fit your lifestyle and if it’s a piece you’ll cherish for years to come.

  2. Finger-flattering shape: The elongated form can make fingers appear longer and more slender.
  3. Versatile design options: Works well in both vintage-inspired and modern settings.
  4. Durability for daily wear: The beveled corners are less prone to chipping than pointed corners.

While a 4-carat emerald cut diamond engagement ring is undoubtedly impressive, it’s essential to balance the desire for a show-stopping ring with practical considerations for long-term wear and enjoyment.

Bought a beautiful stone here for an engagement ring. I was a little apprehensive since you’re buying something unseen. But Cid made it easy. In fact, Nissan, the owner also gave a call to make me more comfortable. They sent me the stone to take to a local jeweler with only my Amex in case I bailed on them.
