N.J. Diamonds has created custom jewelry in Dearborn since 1996. Through Custom by Z, we help clients turn an idea, meaningful stone, family heirloom, or special moment into a piece designed just for them.
Our family-owned jewelry store serves Dearborn and the greater Detroit area. Every custom project receives personal guidance from an experienced designer and support from a team with GIA education in diamonds, colored gemstones, and pearls.
Start With Your Story
A custom design begins with a conversation. You may bring a photo, drawing, loose gemstone, old ring, or simply an idea. We listen to what matters to you, discuss your style and budget, and explain your options in clear language.
Custom jewelry can celebrate an engagement, wedding, anniversary, graduation, new baby, family tradition, or personal achievement. The goal is not to copy someone else’s jewelry. It is to create a piece that feels like yours.
Our Custom Jewelry Design Process
- Consultation: Tell us what you want to create, who it is for, and what the piece should represent.
- Design direction: We review shapes, metals, gemstones, setting styles, size, wearability, and budget.
- Stone selection: Choose from natural or lab-grown diamonds, colored gemstones, pearls, or stones you already own.
- CAD design: Computer-aided design helps you see the proportions and details before the piece is made.
- Approval: We review the design with you and make approved adjustments before production.
- Finishing and inspection: The completed jewelry is polished, inspected, and prepared for you to wear or present.

Custom Engagement Rings by Custom by Z
An engagement ring should fit the person who will wear it. Custom by Z can help you choose the diamond shape, setting, metal, profile, side stones, and personal details that make the ring meaningful.
We work with natural and lab-grown diamonds and explain the important differences before you decide. Our diamond education and GIA training help you compare quality, beauty, documentation, and value with confidence. Visit our diamond buying guide or begin with our custom engagement ring guide.
Redesigning Heirloom Jewelry
Jewelry passed down through a family can have great emotional value even when the style no longer fits. We can evaluate the piece, discuss which stones and metal may be reused, and design something that protects the memory while giving it a new life.
Some older jewelry should be repaired instead of redesigned. We will explain the difference honestly. Our in-store jewelry repair service can also help with ring sizing, prongs, settings, polishing, rhodium plating, and other maintenance.

Experience and Gemological Knowledge
N.J. Diamonds combines design experience with gemological education. Our qualifications include GIA Graduate Gemologist and diamond-grading education, along with GIA studies in colored gemstones and pearls. This knowledge helps us consider beauty, durability, setting security, and everyday wear—not only appearance.
For important pieces, we can also discuss documentation and jewelry appraisal services.
Frequently Asked Questions
How long does custom jewelry take?
The schedule depends on the design, materials, stone selection, and number of revisions. We will explain the expected timeline before work begins.
Can you use my diamond or gemstone?
Often, yes. We must inspect the stone first to evaluate its condition, measurements, and suitability for the new design.
Can you redesign old jewelry?
Yes. We can discuss reusing suitable diamonds, gemstones, and precious metal while preserving the meaning of the original piece.
Do you design with lab-grown and natural diamonds?
Yes. We offer both and help you compare their characteristics, grading reports, price, and long-term considerations.
