4-carat princess cut diamonds offer impressive size and modern appeal, but their prices can fluctuate significantly, as well as diamonds’ value.

This guide shows the key factors influencing the cost of these square-shaped gems, helping you make a smart purchase decision. 

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

Price Range for 4 Princess Cut Diamonds

The price of 4-carat princess 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 $20,000 to $150,000 or more.

At the lower end of the spectrum, you might find 4-carat princess 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. 

Premium 4-carat princess cut diamonds with excellent cut, high color grades (D-F), and top clarity ratings (IF-VVS2) can command prices from $80,000 to $150,000 or more.

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

ColorClarityPrice Range
D-FIF-VVS2$110,000 – $150,000+
G-HVS1-VS2$80,000 – $110,000
I-JSI1-SI2$50,000 – $80,000
K-MSI2-I1$20,000 – $50,000

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 crucial when evaluating a 4-carat princess cut diamond, significantly impacting both its beauty and price. 

While princess-cut diamonds don’t receive official cut grades like round brilliants, their cut quality greatly affects their appearance and value.

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

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

  1. Table percentage: Typically 58-70% is considered ideal for optimal light performance.
  2. Depth percentage: Ideally between 68-75% for balanced proportions.
  3. Symmetry: Ensures the diamond’s facets and overall shape are balanced.
  4. Polish: A smooth surface allows better light entry and reflection.
  5. Length-to-width ratio: For a square princess cut, aim for 1.00-1.05.

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 princess cut diamonds. The color scale for white diamonds ranges from D-Z.

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 princess 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 princess cut 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 princess-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 princess 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 princess 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 princess cut diamonds, consider that their facet pattern can sometimes help mask inclusions. However, due to the step-cut corners, some inclusions may be more visible than in other cuts. Careful selection can allow for some flexibility in choosing clarity grades without compromising visual appeal.

Carat weight

At 4 carats, princess 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 princess 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 princess 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 princess cut diamond: $3,500 – $12,000
  • 2-carat princess cut diamond: $10,000 – $50,000
  • 3-carat princess cut diamond: $18,000 – $100,000
  • 4-carat princess cut diamond: $20,000 – $150,000+

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

Why Should You Buy a 4-Carat Princess Cut Diamond?

Investing in a 4-carat princess-cut diamond offers several compelling advantages:

  1. Impressive size: A 4-carat diamond makes a bold statement, standing out in any setting.

  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. Consider clarity carefully: VS2-SI1 clarity grades often offer the best value, appearing clean to the naked eye.
  9. Assess color in person: Color differences can be subtle; view diamonds in various lighting conditions if possible.
  10. Check for inclusions: Request detailed plots or images to understand the nature and location of any inclusions.
  11. Consider the setting: Choose a setting that complements and secures the large stone effectively, protecting the corners.
  12. Negotiate: Given the high value, there may be room for price negotiation, especially with independent jewelers.
  13. Understand return policies: Ensure the seller offers a reasonable return period for such a significant purchase.
  14. Insurance: Factor in the cost of insuring such a valuable item.
  15. Think long-term: Consider how the diamond will fit your lifestyle and if it’s a piece you’ll cherish for years to come.

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.
