Explore our step-by-step customization service and how we streamlined delivery for a major birthstone necklace chain brand

In the highly competitive world of OEM/ODM stainless steel jewelry, differentiation isn’t just a bonus—it’s a necessity. One of the most in-demand product lines is the birth month flower and birthstone charm necklace, which merges personalization, symbolism, and seasonal appeal into a single, compelling accessory. But what really sets us apart isn’t just the product—it’s the process. From the initial design sketch to the final package arriving at your distribution hub, our streamlined customization service turns complexity into simplicity, offering both flexibility and efficiency at scale.

This page offers a deep dive into our end-to-end service model, and a behind-the-scenes look at how we executed a large-volume order for a major brand with tight timelines and high expectations. Whether you’re exploring OEM partnerships or seeking custom production capabilities, this is your roadmap to how we do custom jewelry differently.

From Vision to Vector: Translating Custom Requests into Production-Ready Designs

The journey starts with an idea—a flower, a birthstone, a month, a memory. Our design process begins with collaborative consultation. We encourage clients to bring their inspirations, be it mood boards, rough sketches, or even screenshots from social media trends. Our in-house design team then translates those concepts into professional 2D renderings, offering multiple iterations based on metal finish, charm shapes, and gemstone cuts.

Once approved, we create precise 3D CAD models using Rhino or MatrixGold. This step is crucial for evaluating proportion, fit, and feasibility—especially important for charm-based pieces where layering and spacing are key to wearability. For items involving colored stones or enamel detailing, we simulate exact Pantone matches during the prototyping phase to ensure color accuracy pre-manufacture.

Turnaround Time: On average, it takes 5-7 working days from initial input to final CAD approval.

Key Features of Our Design Process:

Material Selection and Sample Approval: Built to Last and Delight

All our charms and chains are crafted in hypoallergenic 316L stainless steel, with optional vacuum plating finishes in gold, rose gold, or matte black. The birthstones are sourced from high-grade cubic zirconia with precise facet matching for consistent sparkle across batches. For the birth month flowers, we offer laser engraving or low-relief etching depending on client preference and budget.

After prototype approval, we send out production samples for final inspection. This includes a full necklace presentation with all charms, clasps, and tags—exactly how the final units will appear. For large-volume clients, we even include packaging mockups to ensure full aesthetic alignment pre-mass production.

Case Study: Scalable Customization for a Birthstone Chain Retailer

In Q2 of this year, we fulfilled a 20,000-piece OEM order for a popular DTC brand specializing in birth month flower & stone necklaces. The challenge? Each piece was to be uniquely assembled based on customer birth month, and shipped in curated kits for monthly subscription drops. That meant managing 12 flower designs, 12 gemstone variants, 2 plating finishes, and multiple chain lengths—all under a six-week fulfillment window.

Our solution involved a segmented production plan using parallel batch scheduling:

  1. Pre-Assembly: All base components (charms, chains, clasps) were pre-assembled and stocked.
  2. Batch Kitting: Based on the subscription list, kits were picked and assembled just-in-time by our in-house logistics team.
  3. Labeling & Packaging: Each kit included individual barcodes and subscriber names for direct fulfillment.

By applying lean manufacturing principles and pre-kitting logistics, we cut the standard fulfillment timeline from 12 weeks to just 34 working days—a 29% reduction in lead time. Total unit cost, including packaging and labor, came to $2.71 per necklace, meeting the client’s budget while preserving quality and personalization.

Key Outcomes:

Packaging and Shipping: Designed for Direct Fulfillment

Customization doesn’t stop at the necklace—we offer packaging services optimized for DTC brands and bulk wholesale buyers alike. Clients can choose between branded pouches, magnetic gift boxes, or sustainable flat packs for large shipments. All packaging is done in-house, allowing for brand-matched inserts, custom QR codes, and promotional messaging.

We’ve also partnered with international logistics providers (DHL, YunExpress, 4PX) to support multiple delivery models:

Each necklace kit can be tracked at the SKU level, and we provide monthly shipping reports with delivery KPIs, so brand clients can monitor cost-to-serve and identify fulfillment trends.

Quality Control and Brand Consistency: The Invisible Infrastructure

One of the challenges with large-scale customization is ensuring that each unique piece still meets the same quality benchmark. Our solution? Integrated QC checkpoints at each production phase—design, plating, stone setting, assembly, and packaging.

Each unit passes through a 6-step checklist covering symmetry, finish uniformity, charm order accuracy, and secure fastening. For high-volume clients, we offer video QC walkthroughs and remote audit access to maintain transparency and trust.
