Our Unique Expertise With Antique and Vintage Pieces
At Johantgen Jewelers, our 130-year history gives us a distinctive advantage when working with antique jewelry. We’ve been using time-honored techniques continuously since 1896, which means we understand historical construction methods from direct experience.
Time-Honored Techniques on New and Old Pieces
We apply traditional craftsmanship techniques to both antique restorations and new custom work. This versatility allows us to repair vintage pieces using appropriate methods while also creating new jewelry with the quality and character of earlier eras.
Transforming Old Pieces Into Something New
Many clients bring us antique jewelry they love but don’t wear. We specialize in reimagining these pieces, preserving the precious materials and sentimental value while creating something fresh and wearable. A grandmother’s brooch can become a pendant. An outdated ring can be redesigned while keeping its original stones.
Blending Old and New
We can incorporate traditional techniques into modern designs, giving new pieces the craftsmanship quality of antique jewelry. This approach works beautifully for clients who appreciate vintage aesthetics but want something designed for their own style.
Understanding What Makes Antique Pieces Special
Having worked with jewelry from every era since our founding, we recognize the construction methods, materials, and design elements that give antique pieces their character. This knowledge guides every restoration decision we make.

Restoration Services for Vintage and Antique Jewelry
Every antique piece presents unique considerations. Here’s what we commonly address:
- Structural Stabilization
Antique pieces often need reinforcement without visible modification. Worn shanks, thinned settings, weakened joints. We stabilize structures to prevent future damage while preserving the piece’s appearance and character.
- Prong and Setting Restoration
Old prongs wear, bend, and break. Original settings loosen over time. We restore prongs and settings to secure stones properly, matching the original style and construction.
- Stone Tightening and Replacement
Loose stones are common in antique pieces. We tighten stones carefully, respecting delicate settings. When stones are missing, we source appropriate replacements or match existing stones as closely as possible.
- Clasp Repair and Replacement
Antique clasps wear out, break, or stop functioning safely. We repair original clasps when possible. When replacement is necessary, we source or create clasps that match the piece’s style and work reliably.
- Chain Repair and Restoration
Antique chains often feature links and construction no longer commonly used. We repair antique chains using appropriate techniques, matching original link styles and maintaining the chain’s character.
- Ring Sizing With Period Sensitivity
Sizing antique rings requires special consideration. Some designs can be sized using standard methods. Others have construction that makes traditional sizing difficult. We assess each ring individually and explain what’s possible.
- Enamel Repair
Antique enamel work requires specialized knowledge. We assess enamel damage and discuss repair options honestly. Some enamel can be repaired or stabilized. We’ll tell you what’s realistic for your specific piece.
- Pearl Restringing
Antique pearl necklaces need periodic restringing to remain safe to wear. We restring with appropriate silk thread and proper knotting between pearls.
- Cleaning Without Damage
Antique jewelry requires gentler cleaning methods than modern pieces. We clean antique pieces using appropriate techniques for their specific materials and construction.
- Full Restoration Projects
Some antique pieces need comprehensive work. We approach full restorations carefully, creating detailed plans and discussing every step before proceeding.

How We Approach Antique Jewelry Restoration
Step 1: Listening to the Piece’s Story
Before we examine anything, we want to hear about it. Where did it come from? What do you know about its history? What matters most to you? This context shapes our approach.
Step 2: Careful Examination
We examine your piece thoroughly, assessing construction methods, materials, era, condition, and any previous repairs. This examination often reveals things owners didn’t know about their pieces.
Step 3: Honest Assessment
We tell you exactly what we found, what the piece needs, and what we recommend. We explain the options and their implications. You get honest guidance based on our experience.
Step 4: Discussing Your Goals
What do you want from restoration? A piece you can wear daily? Something for occasional special occasions? Your goals shape the restoration plan.
Step 5: Detailed Plan and Quote
We provide a specific restoration plan describing exactly what we’ll do. You understand the work we’re proposing and why. The quote covers everything.
Step 6: Careful Restoration
We do the work using appropriate techniques for the piece’s era and construction. Original material is preserved wherever possible. Your piece is treated with the respect its significance deserves.
Step 7: Return and Education
When your piece is ready, we walk you through what was done and discuss ongoing care. Antique jewelry often has different care requirements than modern pieces.

Frequently Asked Questions
How do I know if my jewelry is truly antique?
Generally, “antique” means over 100 years old, while “vintage” refers to pieces 20-100 years old. Dating jewelry involves examining construction techniques, materials, hallmarks, and style. We can help assess the age of your pieces during examination.
Will restoration affect my piece’s value?
It depends on the restoration. Careful, appropriate restoration that preserves original character typically maintains or improves value by making pieces wearable and preventing further deterioration. We discuss these considerations when relevant.
How long does antique jewelry restoration take?
Simple repairs might take a week or two. Complex restorations can take several weeks to months. We provide realistic timelines after examining your piece.
How much does restoration cost?
Every piece and restoration is different. We provide detailed quotes after examination so you know exactly what’s involved.
Can you restore pieces that have been poorly repaired before?
Often, yes. We’ve repaired damage from inappropriate previous work. Whether we can fully address previous issues depends on their extent. We’ll give you an honest assessment.

We work on pieces from virtually every era: Victorian, Edwardian, Art Nouveau, Art Deco, Retro, Mid-Century, and vintage pieces from more recent decades.
What if my antique piece is too fragile to restore?
Some pieces are best preserved as display items rather than wearable jewelry. We’ll tell you honestly if that’s the case and discuss alternatives.
