  • Carat Weight: Larger diamonds (1+ ct) typically hold more value.

Frequently Asked Questions (FAQs)

It provides a data-driven estimate based on industry-standard depreciation and quality factors, ideal for preliminary evaluation.

2. Does it guarantee a resale price?
No, but it offers a realistic range that helps you negotiate confidently with buyers or jewelers.

3. Why does certification matter?
Certifications like GIA or AGS add trust and standardization, which enhances resale value.

4. What if my diamond has no certification?
The calculator factors this in and reduces the value accordingly. Consider getting your diamond appraised.

5. Why does the shape affect trade-in value?
Some shapes, like round, are more popular and liquid in the resale market, increasing demand and value.

6. Can I use the calculator for fancy colored diamonds?
The calculator is optimized for standard white diamonds. Fancy colors may require special appraisal.

7. What if I overpaid originally—does the tool adjust for that?
It uses your original price as a base, but factors like quality and certification help normalize the estimate.

8. Do diamonds appreciate over time?
Generally, no. Most diamonds depreciate, but high-quality, rare stones can retain or slightly appreciate.

9. Is this tool useful for insurance valuation?
No. Insurance requires appraisal replacement value, which is typically higher than resale.

Most diamonds resell for 30%–70% of their original price, depending on quality, age, and market trends.

11. Does brand (like Tiffany or Cartier) matter?

It’s bracketed: 1 year = ~20%, 3 years = ~30%, 7 years = ~40%, and so on.
