A Complete Guide to the Custom Jewelry Design Process and Timeline

A custom fine jewelry commission typically requires between four and eight weeks from the first sketch to the final polish. The process transforms raw, ethically sourced materials or inherited family gold into a singular piece of wearable art. At Nanna Schou, we build every bespoke piece around the story of the person who will wear it. You are not just picking a ring out of a display case; you are actively participating in the creation of a future heirloom.

When you start the custom jewelry design process, you enter a collaboration. We translate your ideas, memories, and aesthetic preferences into a tangible object using traditional Danish goldsmithing techniques. Whether you are commissioning a completely new engagement ring or asking us to melt down and redesign a grandmother’s wedding band, the steps remain grounded in precise craftsmanship. We map out the exact sequence below, detailing what happens at our workbench and what you can expect at every stage of the commission.

1. The Initial Consultation: Defining Your Story

The foundation of any bespoke piece is the initial conversation. We start by discussing who the jewelry is for, how they live, and what the piece represents. A ring meant for daily wear by someone who works with their hands requires a fundamentally different structural approach than a pendant worn only on special occasions.

During this meeting at our central Copenhagen atelier, we look at references together. We encourage you to bring photographs, mood boards, or existing pieces of jewelry you admire. We also discuss your practical requirements, including timelines and financial expectations. Custom engagement rings in Copenhagen typically cost between DKK 15,000 and DKK 50,000, depending on the stone and metal choice. Naming a realistic figure early allows us to suggest the right materials and design complexity to meet your exact parameters.

Bringing Heirloom Pieces to the Table

In our experience, over half of our custom commissions begin with jewelry that has sat unworn in a drawer for years. If you want to repurpose old jewelry, you bring those pieces to this first meeting. We weigh the gold, examine the stones under a loupe to check for damage, and discuss which elements we can salvage. Old diamonds and sapphires carry a history that adds profound emotional weight to a new design, and we evaluate exactly how to protect them during extraction and resetting.

Establishing the Functional Requirements

We also spend time talking about the physics of the piece. If you want a tall, delicate prong setting for an engagement ring, we evaluate how that fits into your daily routine. We might suggest a lower profile or a bezel setting if you have an active lifestyle, protecting the center stone from impacts. This phase is about aligning your visual desires with the structural realities of precious metals.

2. Sourcing Ethical Materials for Custom Designs

Once we agree on a general direction, we move to material sourcing. We work exclusively with high-quality, traceable materials, favoring 18K gold and ethically sourced gemstones. The jewelry industry has changed significantly over the last decade, and modern buyers prioritize the origin of their materials just as much as the final aesthetic.

"Fine jewelry consumers are increasingly demanding transparency, with 59% of shoppers willing to pay a premium for sustainably sourced materials." — McKinsey & Company State of Fashion: Watches and Jewellery, 2021

We take this responsibility seriously. We source our diamonds through suppliers who strictly adhere to the Kimberley Process, and we trace our colored gemstones back to responsible mining operations whenever possible.

Choosing Your Precious Metals

For most fine jewelry, we recommend 18K gold. Pure 24K gold is entirely too soft for jewelry that sees daily wear. By alloying pure gold with other metals, we create 18K gold—which consists of 75% pure gold and 25% alloying elements. This specific ratio provides the perfect balance: it retains the rich, warm color of pure gold while gaining the hardness necessary to hold stones securely.

Depending on the alloying metals used, we can create different colors:

• Yellow Gold: Alloyed with a mix of silver and copper to maintain a classic, warm hue.
• White Gold: Alloyed with palladium or silver, often plated with rhodium for a bright, reflective finish.
• Rose Gold: Alloyed with a higher percentage of copper, giving the metal a distinct pinkish-red tint.

Navigating Diamonds and Colored Gemstones

If your design requires stones, we curate a selection for you to view in person. We source diamonds, sapphires, and tourmalines based on your specific brief. We evaluate stones not just on their grade, but on their character. A rose-cut diamond, for instance, offers a subtle, antique glow that differs entirely from the sharp brilliance of a modern round cut.

When choosing a center stone, we always discuss durability using the Mohs scale of mineral hardness.

We lay the stones out in our atelier so you can observe how they react to natural light. You choose the exact gem that will sit at the center of your design.

3. The Design Phase: Sketches and Revisions

With the materials selected, we move to the drawing board. We translate the ideas from our consultation into hand-drawn sketches. This step bridges the gap between imagination and reality, allowing you to see the proportions of the piece before we touch any metal.

We typically provide two to three design variations based on our initial conversation. We draw the piece from multiple angles, detailing the thickness of the band, the style of the setting, and the exact placement of any accent stones. We calculate the dimensions in fractions of a millimeter, as even a 0.5mm change in band width drastically alters how a ring feels on the hand.

You review the sketches, and we refine them based on your feedback. We adjust the curve of a prong, the texture of the band, or the orientation of the center stone until the design matches your vision perfectly. You can browse examples of our custom jewelry designs to see how our previous sketches have translated into finished pieces. Once you approve the final sketch, we lock in the design and move to the workbench.

4. The Goldsmithing Craft: Inside Our Copenhagen Atelier

This is where the physical transformation happens. Unlike mass-produced jewelry poured into standardized molds by the thousands, bespoke pieces require intensive hand-fabrication. We build the jewelry from scratch using tools that goldsmiths have relied on for centuries.

Melting and Forging the Metal

We begin by melting the gold in a crucible. Using a high-heat torch, we bring the 18K gold to roughly 900 degrees Celsius until it pools into a glowing liquid. We pour this liquid metal into an ingot mold, creating a solid bar of gold.

From there, the physical labor begins. We pass the gold bar repeatedly through a rolling mill, compressing and stretching the metal into a sheet or a wire. This process, known as work-hardening, aligns the crystalline structure of the gold, making the final piece significantly stronger than a simple cast ring. We anneal the metal—heating it to soften it—and then roll it again, repeating the cycle until we achieve the exact thickness required for your design.

We cut the metal with fine jeweler's saw blades, file the edges to perfect smoothness, and use pliers and hammers to forge the metal into its final shape. We solder the seams using a precise flame, joining the metal permanently. If you are curious about the physical space where this happens, you can read more about our Copenhagen jewelry workshop.

Precision Stone Setting

Setting the stones is the most delicate part of the goldsmithing process. We do not use glue; stones are held in place entirely by the tension and structure of the surrounding metal.

Using specialized burrs, we carve a precise seat for the stone into the gold. We place the stone into the seat and carefully move the metal over the edges of the gem to secure it. If we are crafting a bezel setting, we hammer a thin rim of gold entirely around the stone's perimeter. For a prong setting, we file the tips of the gold wires and bend them perfectly over the crown of the diamond or sapphire. This requires absolute precision under a microscope, as too much pressure can fracture the stone, and too little leaves it loose.

5. Redesigning Heirloom Jewelry

Redesigning old jewelry requires a specific set of skills and a deep respect for the material's history. When you bring us inherited jewelry, we are not just recycling metal; we are preserving a physical connection to your family's past.

The chemistry of old gold can be unpredictable. A vintage 14K ring contains alloys that may have become brittle over decades of wear. When we melt it down to forge a new piece, we must carefully manage the refining process.

We follow a strict sequence for heirloom redesigns:

1. Extraction and Cleaning: We carefully remove all existing diamonds or gemstones from the antique settings, cleaning decades of built-up residue to reveal their true color.
2. Assaying the Metal: We test the karat of the old gold to understand its exact purity.
3. Melting and Alloying: We melt the old pieces down in a crucible. Often, we add fresh fine gold or new alloying metals to improve the workability and durability of the vintage gold.
4. Fabrication: We forge the newly mixed gold into the modern design you approved during the sketch phase.
5. Resetting the Stones: We set your family's original stones into the new piece, giving them a second life in a contemporary setting.

The result is a structurally sound, modern piece of jewelry that physically contains the exact gold and stones worn by your ancestors.

6. Timeframes and Deliveries for Custom Pieces

Patience is a requirement for custom goldsmithing. We do not rush the process, as every step requires precise attention to detail. A standard custom commission takes between four and eight weeks from the day you approve the final sketch.

Here is how that time breaks down:

• Weeks 1-2 (Sourcing): If your design requires specific gemstones, we spend the first two weeks calling our trusted suppliers, bringing in stones for you to view, and securing the exact materials needed.
• Weeks 3-5 (Fabrication): The bulk of the time goes into the physical making of the ring. Forging, soldering, and filing take dedicated hours at the bench.
• Week 6 (Setting and Polishing): We set the stones and apply the final finish—whether that is a high-polish shine, a matte brushed finish, or a hammered texture.
• Week 7-8 (Hallmarking and Buffer): In Denmark, the law requires all precious metals to carry a registered name stamp and a fineness mark (such as 750 for 18K gold). We stamp our pieces with the "NS" mark to guarantee authenticity. We also build a buffer into the schedule to handle any final adjustments.

If you have a strict deadline—such as a planned proposal or a wedding date—you must communicate that during our very first meeting so we can reserve the necessary time at the bench.

7. Pricing the Custom Jewelry Design Process

Understanding the cost structure of bespoke jewelry helps you plan your commission effectively. Our custom pieces range broadly from DKK 1,200 for simple silver work to DKK 62,000+ for complex 18K gold designs featuring large, high-quality diamonds or sapphires.

Three distinct factors drive the cost of a custom piece:

1. Materials: The current market price of 18K gold, combined with the rarity, size, and quality of the specific gemstones you choose, dictates the base cost.
2. Labor and Complexity: A simple, solid gold wedding band requires fewer hours at the bench than a platinum ring featuring a complex halo setting with twenty micro-pavé diamonds. You are paying for the dedicated hours of a trained goldsmith.
3. The Design Process: Custom work absorbs design hours that ready-made pieces do not. We spend time sketching, revising, and sourcing specifically for you.

Because the design hours for our collection pieces are already amortized, purchasing from our ready-made fine jewelry collection will always cost less than commissioning a bespoke piece of identical weight. If you want to contribute to a loved one's future custom project without making the design choices for them, we recommend exploring our available gift cards.

Frequently Asked Questions

How long does it take to make a custom ring? A custom ring takes between four and eight weeks to complete. This timeline begins after we finalize the design and includes material sourcing, hand-forging the metal, stone setting, and official hallmarking.

How much does a custom engagement ring cost in Copenhagen? Custom engagement rings in Copenhagen typically cost between DKK 15,000 and DKK 50,000. The final price depends entirely on the size and quality of the center stone, the complexity of the setting, and the weight of the 18K gold or platinum used.

Can I use my own old gold for a new design? Yes, we frequently melt down and repurpose customer-supplied heirloom gold. We assay the metal, melt it in our crucible, and forge it into a completely new design, allowing you to retain the sentimental value of inherited jewelry.

Do you work with ethical diamonds? We exclusively source diamonds through suppliers who comply with the Kimberley Process. We also offer lab-grown diamonds and traceable colored gemstones for clients who prioritize highly documented ethical supply chains.

What is the difference between 14K and 18K gold? 18K gold contains 75% pure gold, while 14K gold contains 58.5% pure gold. We primarily recommend 18K gold for custom fine jewelry because it offers a richer, warmer color while maintaining the necessary durability for daily wear.

Do I need an appointment for a custom jewelry consultation? Yes, you need to book an appointment for custom design meetings. This gives us the dedicated, uninterrupted time needed to discuss your ideas, review sketches, and look at gemstone options in our atelier.

Taking the Next Step

The most critical decision in any custom jewelry project is identifying the center stone or the heirloom gold you plan to use, as the entire structural design must respond to those specific physical dimensions. Gather your inspiration, locate any old family jewelry you want to repurpose, and bring them to the workbench. We will detail exactly how we secure those precious stones in our upcoming article on traditional bezel and prong setting techniques.
