We Buy Gold and Precious Metal

Bring valid identification and ask questions before deciding. You are never required to accept an offer.

Jewelry Cleaning and Ongoing Care
Regular inspection and cleaning can help identify worn prongs, loose stones, weakened clasps, and other developing problems. Cleaning and polishing are included with our jewelry repairs, and we can recommend care appropriate for the metal, gemstones, and construction of your piece.
Jewelry purchased from N.J. Diamonds may include ongoing service benefits. Ask our team what maintenance is included for your specific purchase.

Frequently Asked Questions
Do I need an appointment?
You can visit for many initial questions and inspections, but contacting us first is helpful for custom-design consultations, appraisals, or projects that may require additional time.
Are jewelry repairs completed in-store?
Yes. Jewelry repair work is completed at our Dearborn location rather than shipped to another city or state.
Can you use my diamond or gemstone in a custom design?
Often, yes. We must inspect the stone first to evaluate its condition, measurements, and suitability for the proposed design.
Do you work with natural and lab-grown diamonds?
Yes. We offer both and explain their origins, reports, quality characteristics, pricing, and other considerations before you decide.
Where is N.J. Diamonds located?
