FAQs

1. What does this calculator estimate?

It estimates replacement, fair market, resale, and insurance-oriented values from metal, gemstones, workmanship, condition, premiums, and market adjustments.

2. Why is purity important?

Purity changes how much valuable metal the ring actually contains. Higher purity usually increases the metal portion of the valuation.

3. Does brand premium always matter?

No. Brand premium matters most when the ring has recognized market demand, verified origin, or collector appeal.

4. Is replacement value the same as resale value?

No. Replacement value estimates what it may cost to replace the piece. Resale value estimates what a secondary buyer may actually pay.

5. How are diamonds and gemstones included?

The calculator multiplies carat weight by a user-entered rate. You can use different rates for center and side stones.

6. Why include repair cost?

Repair cost lowers fair market value because buyers often discount pieces needing restoration, resizing, polishing, or stone tightening.

7. Can I use custom market rates?

Yes. Enter your own metal and stone rates to reflect supplier quotes, auction data, or current local pricing.

8. Is this enough for formal insurance?

It is useful for planning and comparisons. Formal insurance usually requires a certified appraisal, supporting documentation, and current market evidence.
