After you buy: protect it
Most buyers skip these steps — don't be most buyers.
Get an independent appraisal
Within 30 days. GIA-trained appraiser. Cost: $50–$150.
Establishes "replacement value" — typically 20–50% higher than purchase price. Your insurance company needs this number.
Record your GIA report number
Often laser-inscribed on the girdle. This is the diamond's fingerprint.
If lost or stolen, the GIA number proves what you had. Verify at gia.edu/report-check.
Insure immediately
Before you propose or the day you take delivery. Jewelers Mutual or Lavalier recommended.
Standalone jewelry insurance: 1–2% of appraised value per year. Covers loss, theft, damage, mysterious disappearance.
Understand replacement value
Insurance pays appraised replacement value, not what you paid.
Re-appraise every 2–3 years. Prices fluctuate.
Set up maintenance
Prong checks every 6–12 months. Cleaning, replating for white gold.
Loose prongs are the #1 cause of lost stones. Many policies require maintenance proof.
