How to actually build a niche jewelry brand when the market is already saturated? Let’s look to Rosie, founder of Deja Marc, who focuses on fingerprint jewelry. Even though it’s a familiar “crafty” idea, she turned this Christmas inspiration into a luxury scablable business and made $400K in her first year.
Inspired by Moms Often Overlooked
The spark for Deja Marc came from a deeply personal place. At the time, many of Rosie’s friends were entering the baby stage, and gift-giving had become part of the routine. She noticed a small but powerful moment everyone else seemed to miss: all eyes were on the baby, and no one was really thinking about the mom going through one of life’s biggest changes.
She wanted a meaningful keepsake that was as heartfelt as a handwritten card but as lasting as fine jewelry. It had to celebrate the mom, connect her to the baby, and preserve this sacred moment forever. She took that one insight and ran with it.
How the Product Gets Made
Customers provide a personal fingerprint, or even something as unique as a pet’s nose print, and the seller turns it into a customized piece of jewelry. The entire process can be completed online.
Once an order is placed, the sellor sends out a fingerprint collection kit. The customer takes their imprint and sends it back. The design is then digitized, refined, and engraved onto the final piece before being produced and delivered.
Generally, the market splits into two main approaches:
The 3D Molded Approach (Competitors):
Most of Rosie’s competitors rely on lost-wax casting. They take the customer’s physical imprint, scan it, create a digital model, and then use 3D printing or wax carving to produce a mold before casting it in metal. While this method captures the original imprint closely, the final result often feels more handcrafted and less refined, lacking the clean finish typically associated with fine jewelry.
The Precision Engraving Approach (Deja Marc):
Instead of molding, Deja Marc relies on CNC engraving. Each fingerprint is translated into a flat, engraved surface, resulting in a look that is much cleaner, more polished, and aligned with fine jewelry aesthetics.
How to Replicate Her 9-to-5 Startup Process in 8 Months
Brand positioning & Supply chain setup
We can look at how Rosie did it. She started by quickly defining the brand positioning and securing a reliable supply chain. Rosie decided Deja Marc would be a fine, luxury jewelry brand with highly personalized products. She carefully selected a fingerprint kit supplier, who has remained a partner ever since, ensuring consistent quality and a smooth customer experience.
For production, she initially considered outsourcing since she was still working a full-time job. After visiting several studios in person, she realized the samples did not meet her standards. Determined to maintain full control over the quality and precision of each piece, she purchased an engraving machine and taught herself how to operate it.
Finding the "resonance" marketing angle
Meanwhile, marketing focused on creating compelling content that appeals to their audience and keeping it fresh. Running Meta ads proved the most efficient approach so far, but the key was identifying what truly resonated with potential customers.
Interestingly, the top-performing ads did not even feature the jewelry itself. A simple video of Rosie and her daughter using the fingerprint kit struck a chord with viewers and drove orders. Through these campaigns, Deja Marc explored many emotionally resonant real-life scenarios, sparked conversations, gathered ideas, and iterated content quickly.
Streamlining operations, production & order fulfillment
As the business grew, coordinating production and fulfilling orders became increasingly complex, especially since each piece was fully customized and offered seven-day shipping.
Initially, Rosie manually tracked every kit and order using spreadsheets, checking when kits were sent out, returned, and ready for engraving. Over time, she developed a production platform to track all kits in transit and ensure each one entered the workflow promptly upon return.
Building this full process took about eight months. Eventually, she left her full-time job to focus entirely on the business.
Build a Lean, Profitable Jewelry Supply Chain
In fine jewelry, most pieces are made from precious jewelry metals like 10k, 14k, or 18k gold, silver, and genuine gemstones. Production ranges from handcrafted techniques to machine-assisted methods like CNC milling and laser engraving. Prices usually start from $500, with a focus on lasting value and durability.
Fashion jewelry focuses on trendy designs and personalization. Materials are often less expensive but durable enough to create stylish looks. Deja Marc bridges both worlds in material and style. It uses 9k/14k solid gold, 18k gold-plated silver, and sterling silver 925, but applies them to custom, fashion-forward designs.
In terms of production, what Rosie did differently was finding a sweet spot in between. Deja Marc keeps production in-house, starting from semi-finished basic jewelry blanks that are directly sourced from suppliers. This process is perfectly suited to the fingerprint niche, with each piece then customized and finished with precise engraving.
Numbers Behind Upfront Costs, Profit, and Scale
Let’s take a closer look at the actual numbers. This setup keeps the business lean. The biggest upfront cost is the equipment, totaling around $30,000. Marketing is the next largest expense, taking up roughly 20%–30% of the budget in the early stages.
With these costs, the business can sustain a profit margin in the range of 10%–20%. At the same time, the model allows the company to scale, reaching around $400K in revenue in its first year.
