Diamond Price Calculator
When shopping for or selling a diamond, knowing its estimated value is crucial. However, with the vast range of factors that influence pricing—like carat weight, clarity, color, and cut—it’s not always easy to determine a fair market price. That’s where our Diamond Price Calculator comes in.
This free online tool is designed to give you a quick and reasonably accurate estimate of your diamond’s value. Whether you’re a buyer, seller, or simply curious, this calculator is an essential resource for anyone involved in diamond transactions.
💎 What Is the Diamond Price Calculator?
The Diamond Price Calculator is an interactive tool that lets you input specific diamond attributes—carat weight, clarity, color grade, and cut grade—and then provides an estimated price based on industry-standard pricing models.
Our pricing model incorporates realistic multipliers for clarity, color, and cut, along with a base price per carat associated with each clarity level. The goal is to offer a reliable estimate that reflects current market expectations.
🛠️ How to Use the Diamond Price Calculator (Step-by-Step)
Using the calculator is simple and user-friendly. Follow these steps to estimate your diamond’s price:
- Enter Carat Weight:
Input the carat value of your diamond (e.g., 0.75, 1.00, 1.50). The calculator accepts decimal values starting from 0.01. - Select Clarity Grade:
Choose from grades like FL (Flawless), IF (Internally Flawless), VVS1, VVS2, VS1, VS2, SI1, SI2, I1, or I2. These grades reflect how clear the diamond is. - Choose Color Grade:
Select from D (most colorless and valuable) down to J (slightly tinted). D-grade diamonds command premium prices. - Pick Cut Grade:
Options range from Excellent to Poor. Cut impacts how well the diamond reflects light, heavily influencing its brilliance and price. - Click “Calculate”:
The tool processes the inputs and displays an approximate price, based on real-world pricing logic. - Reset if Needed:

🔍 Practical Examples
Let’s explore how the calculator works in practice:
Example 1:
- Carat Weight: 1.00
- Clarity: VS1
- Color: F
- Cut: Excellent
Calculation:
Base price for VS1 = $12,000
Color multiplier for F = 1.1
Cut multiplier for Excellent = 1.2
Final Price = 1.00 * 12,000 * 1.1 * 1.2 = $15,840
Example 2:
- Carat Weight: 0.75
- Clarity: SI2
- Color: H
- Cut: Good
Calculation:
Base price for SI2 = $6,000
Color multiplier for H = 1.0
Cut multiplier for Good = 1.0
Final Price = 0.75 * 6,000 * 1.0 * 1.0 = $4,500

❓ Frequently Asked Questions (FAQs)
1. Is this diamond price estimate accurate?
It’s a close approximation based on standard pricing models. Actual prices may vary by jeweler or market conditions.
2. What is the most important factor in diamond pricing?
Carat weight has the most direct impact, but clarity, color, and cut significantly influence overall value.
3. Can I use this tool for lab-grown diamonds?
This calculator is optimized for natural diamonds. Lab-grown diamonds often have different price structures.
4. Is D color better than J color?
Yes. D is colorless and more valuable, while J may show a noticeable yellow tint.
5. What does clarity mean in diamonds?
Clarity refers to the presence of internal or external imperfections (inclusions and blemishes). FL (Flawless) is the highest grade.
6. How does the cut affect price?
A better cut (like Excellent) increases brilliance and value. Poorly cut diamonds appear dull and are less desirable.
7. What’s a good carat weight for an engagement ring?
1.00 carat is a popular choice, but personal budget and style matter more.
8. Is VS1 clarity better than SI1?
Yes. VS1 has fewer and smaller inclusions compared to SI1, resulting in higher value.
9. What’s the difference between VVS1 and VVS2?
Both are very high clarity grades, but VVS1 has slightly fewer inclusions than VVS2.
10. Does diamond shape affect the price?
Yes, but this calculator doesn’t include shape. Round cuts typically cost more than fancy shapes.
11. Can I use this to price antique diamonds?
You can get an estimate, but antique or vintage diamonds may carry historical or stylistic premiums.
12. How often are diamond prices updated?
Market prices fluctuate based on supply and demand, typically reviewed quarterly by industry professionals.
13. Does this calculator include taxes or setting costs?
No. It estimates the raw diamond value, not the cost of the ring or jewelry setting.
14. Is it safe to use this tool online?
Yes, it doesn’t collect personal data and runs entirely in your browser.
15. Can jewelers charge more than this estimate?
Absolutely. This is a baseline. Jewelers may include branding, service, and overhead in their pricing.
16. Why is the same carat diamond priced differently?
Because clarity, color, and cut vary. A 1.00 carat diamond could cost $3,000 or $30,000 depending on those factors.
17. Can I use this tool on mobile?
Yes, the tool is mobile-friendly and works on all modern devices.
18. Does this include resale value?
It shows an estimated retail value. Resale prices are usually lower unless the diamond is rare or branded.
19. How do I find the actual specs of my diamond?
Check the certificate from GIA, AGS, or IGI. It lists carat, clarity, color, cut, and more.
20. Can I link to this tool on my site or blog?
Absolutely! Feel free to share the tool with your audience for educational or commercial purposes.
