Explore our end-to-end OEM/ODM process and how we streamlined cost & lead time for a major charm necklace order

In the ever-evolving landscape of stainless steel jewelry manufacturing, custom OEM/ODM solutions have become the gold standard for brands that want to stand out. Whether it’s signature pieces for retail lines or branded collections for influencers and chains, custom charm jewelry delivers unmatched personalization and market value. At Custom Magic Studio, we take pride in offering a refined, end-to-end process designed to bring your vision to life efficiently and affordably.

Today, we take you behind the scenes of one of our most complex and rewarding projects: a fully customized birth month flower & birthstone charm necklace designed for a nationwide fashion accessories chain. This deep dive explores not only our process from concept to fulfillment, but also how we helped the client reduce per-unit cost by 18% and cut lead time by nearly 30%.

From Vision to Vector: The Initial Design Discovery Phase

The journey starts long before metals are cast or stones are set. Every successful OEM/ODM project begins with intentional, collaborative design exploration. For our birth month charm necklace client, we began with a multi-session consultation to gather:

Our in-house design team translated this into a full vector concept pack. Each charm (12 flowers and 12 stones) was digitally rendered in variations—flat silhouettes, 3D bas-relief, and etched outlines—based on initial market testing data provided by the client. We also incorporated mood boards and metal finish samples to align expectations early on.

Pro tip: We encourage all B2B clients to bring reference items or Pinterest boards. This helps our designers anticipate style preferences while staying within feasible production specs.

Prototyping & Engineering: Balancing Aesthetics with Manufacturability

Once digital proofs were approved, our engineering team moved swiftly into 3D modeling and prototyping. This stage is critical for aligning art with functionality, especially for layered charm designs where resin-filled or stone-inset components are involved.

For this necklace set, each pendant featured:

We used rapid SLA resin printing for initial samples, allowing the client to feel the proportions and review charm articulation on chain prototypes. Two iterations later, the final approved prototype was ready for die creation and mold machining.

During prototyping, we also performed torque and tensile stress tests on the chain and charm connectors to ensure durability under daily wear. Based on results, we reinforced jump ring thickness and switched to a double-link anchor chain for added strength—without compromising visual delicacy.

Scaling Smart: Production Planning for Cost & Lead Time Efficiency

With final designs locked in, our next challenge was production optimization. The client required an initial batch of 10,000 sets to launch with their spring gifting campaign—each containing 1 necklace, branded card, and retail packaging. Here’s how we reduced both cost and time:

1. Shared Mold Technique

Instead of creating 12 completely separate molds, we engineered a multi-cavity shared base mold for the charm silhouettes. Each flower shape was interchangeable at the casting stage via removable matrix inserts. This alone saved an estimated $2,400 in tooling costs and reduced mold changeover time by 60%.

2. Modular Assembly Workflow

We introduced a semi-automated assembly line that allowed each element—base, flower, stone, jump ring, and chain—to be prepped in modular stations and batch-assembled. This dramatically cut down lead time during the bottleneck finishing phase.

3. Bulk Finishing and Coating

By synchronizing all charms through a unified electroplating and polishing cycle, we avoided redundant labor on sub-variants. Our satin gold finish was applied uniformly in one cycle, with QC stations intercepting any variances before final packaging.

The result? A per-piece production time of just 4.2 minutes, and full order completion within 21 calendar days from mold sign-off. Compared to an initial forecast of 30 days, that’s nearly a 30% time reduction.

Custom Packaging & Fulfillment: Designed to Sell, Built to Ship

No premium custom jewelry project is complete without matching packaging. For this client, the brief included:

We handled all packaging design and sourcing in-house to eliminate third-party margin stacking. Our warehouse coordinated kitting by month and SKU-tagged each set by regional demand forecast data supplied by the client. Orders were shipped FOB Shenzhen, with DDP logistics coordination into their U.S. fulfillment centers within 9 days of production close.

This integrated solution ensured our client was retail-ready across 300+ stores and two online channels, just in time for their spring gifting campaign launch.

Client Success Metrics: The Impact in Numbers

This OEM/ODM project didn’t just produce beautiful necklaces—it delivered measurable business wins. Here are a few highlights:

Our client later shared that the necklace collection ranked #2 in their seasonal gift category and outperformed expectations in both sell-through and customer reviews—citing perceived craftsmanship and design novelty as key drivers.
