Diamond and colored-gemstone jewelry purchased from N.J. Diamonds includes a professional appraisal at no additional charge. The appraisal provides documentation that can help you discuss appropriate insurance coverage with your insurance provider.

Appraisals for jewelry purchased elsewhere
We also provide professional insurance appraisals for qualifying jewelry purchased elsewhere. Each piece is examined in person by an experienced professional using gemological knowledge and equipment—not an AI estimate or photograph-only guess. The appraiser evaluates the metal, gemstones, settings, condition, and identifying details.
What to expect
- Bring the jewelry to our Dearborn store for an in-person examination.
- Bring any existing grading reports, receipts, or previous appraisals you have.
- We will explain the appraisal fee before beginning work on jewelry purchased elsewhere.
- Completion time depends on the number and complexity of the items; ask about the current turnaround when you visit.
Why current documentation matters
Jewelry values and replacement costs can change. Updated documentation can help your insurer understand what you own and what it may cost to replace with a comparable item. Your insurance provider determines coverage, limits, and claim requirements, so review the completed appraisal with your agent.
