Explore our OEM/ODM workflow with delivery speed & cost wins from a real chain brand case

For B2B buyers seeking reliable, scalable, and design-driven stainless steel jewelry solutions, our OEM/ODM capabilities unlock the full potential of brand customization. In this feature, we walk you through the entire process—from idea to delivery—specifically tailored for custom birth month flower and birthstone charm necklaces. With a focus on production flow, time-to-market, and cost efficiencies, we’ll also share a real-world case study showcasing how we helped a national retail chain reduce cost-per-unit and meet aggressive timelines for a large seasonal rollout.

Design to Delivery: Our Full Customization Workflow

Our OEM/ODM jewelry workflow is engineered to minimize friction while maximizing creativity, efficiency, and transparency. Here’s how we turn a sketch into a finished necklace:

1. Concept Development & Design Translation

Clients typically provide a sketch, design reference, or verbal concept. Our in-house CAD design team translates that into a 3D rendering. For birth month charms, we carefully model florals (e.g., rose for June, chrysanthemum for November) and pair them with matching birthstones in bezel or claw settings. Each design undergoes feedback loops until fully approved.

• CAD turnaround: 2–3 business days
• Rendering options: 2–5 variations based on complexity
• Material specs: 316L stainless steel, PVD gold/rose gold, enamel, cubic zirconia or lab stones

2. Prototyping & Sampling

Once the design is approved, we move to mold creation and sample casting. Prototypes are tested for size, color accuracy, and functionality (especially necklace clasp and charm attachment points). Revisions are made if tolerances are off by more than 0.2mm or if visual appearance deviates from renderings.

• Lead time for sample: 7–10 business days
• Revision samples: 3–5 days each round
• Sample shipping options: DHL, FedEx (3–5 days intl.)

3. Bulk Production

After final sample approval, we begin mass production. Our chain necklaces are produced in batches of 500–5000 pieces using precision stamping and casting. Birthstone charms are mounted post-polish to prevent scratching. Each item undergoes quality control checks for color match, stone tightness, and metal smoothness.

• MOQ: 300 pcs/design
• Production cycle: 18–25 days depending on order size
• Customization available: Engraving, packaging, card inserts

4. Packaging & Delivery

Our logistics team provides full service packing including barcode labeling, branded cards, and polybagging. We offer options for eco mailers, velvet boxes, or retailer-specified kits. Bulk orders are consolidated at our warehouse for final QC before international dispatch.

• Shipping: Sea (15–35 days) or Air (5–8 days)
• Tracking & insurance: Included
• Cost per unit optimization: Full breakdown provided with each quote

Case Study: Chain Brand Order Optimization

Client Profile: National Chain Retailer

This U.S.-based fashion retailer required 15,000 units of birthstone flower necklaces for a Mother’s Day promotion across 400+ stores. The brief: unique floral-birthstone combos for each birth month, fully branded packaging, and delivery within 50 days.

Challenges:

• Tight 50-day turnaround window including prototyping
• Multi-SKU management (12 birthstones, 12 flower charms)
• Cost-per-unit ceiling: under $3.20 including packaging

Our Solutions:

• Rapid CAD & sample parallelization: We split design work across two CAD teams, enabling the birthstone and flower designs to be processed concurrently.
• Mold merging: By engineering modular molds (e.g., shared charm base with interchangeable flower tops), we reduced mold count by 30%.
• Pre-packaging prep: While final samples were being reviewed, we began kitting branded inserts and boxes to shave off 3–4 days from the final fulfillment phase.
• Hybrid logistics: Combined sea + air shipping ensured 70% of units arrived before launch while the rest replenished stores in the following week.

Results:

• Final delivery: 48 days from sketch to shelf
• Cost per unit: $2.96 (13% under budget)
• Defect rate: Under 0.5%
• Client reorder: Two follow-up batches for Father’s Day & back-to-school

This case exemplifies our ability to compress development cycles and manage complexity at scale without compromising aesthetics or cost control.

Customization Service Highlights That Set Us Apart

Industry-Benchmark CAD & Rendering

Our digital prototyping tools allow for ultra-precise detailing, including stone facets, petal curvature, and layered textures. Clients receive both 3D renders and 360° spinning views for evaluation. This enables faster approvals and fewer prototyping rounds.

Flexible Materials & Finishing

We offer durable and hypoallergenic stainless steel bases with PVD finishes that resist tarnishing. Clients can choose from:

• Gold-tone, silver-tone, rose gold, black
• Soft or high-polish luster
• Custom stone cuts or engravings

Speed-First Operations

With an in-house design, tooling, and logistics team, we streamline every step. By pre-allocating mold slots and running 24-hour casting lines during peak seasons, we avoid the usual bottlenecks that plague many suppliers.

Transparent Quoting & Live Tracking

Every client receives a detailed quote that breaks down cost components—mold, labor, materials, packaging, logistics—so you know exactly where your money goes. Once production begins, we provide live tracking dashboards updated daily.

Post-Sale Support & Scalability

Whether you need 300 pieces or 30,000, we can scale. We also offer reorder pricing, off-season manufacturing incentives, and priority access to our design team for repeat customers. Our after-sale support ensures replacements or reworks are handled swiftly if ever needed.
