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?
