Quality‑First OEM/ODM Jewelry Manufacturing for Brands
Store Role: AIU Jewelry’s comprehensive OEM/ODM manufacturing line for quality‑focused jewelry brands, covering fine, bridge, and premium fashion jewelry.
Important: Product specifications, MOQ, lead time, testing, compliance support, and manufacturing route must be confirmed according to the specific design, material, finish, quantity, and destination market.
1. Company Positioning
AIU is a quality‑first custom jewelry manufacturer focused on product development, manufacturing consistency, repeat production, and long‑term brand partnerships.
We support jewelry brands, professional wholesalers, importers, e‑commerce sellers, retail groups developing private‑label or proprietary collections, and design‑driven companies that need more than ready‑stock sourcing.
Our core value is not tied to one material. AIU combines product development support, practical manufacturing judgment, controlled finishing, quality management, compliance‑oriented production, confidential development, and scalable repeat‑order support.
AIU does not focus on individual retail purchases, one‑piece personal customization, dropshipping, ready‑stock resale, or sourcing driven only by the lowest possible price.
2. Product & Collection Focus
AIU supports custom jewelry collections across fine, bridge, and premium fashion segments. We manufacture both commercially scalable everyday jewelry and technically demanding designs that require stronger casting, engineering, finishing, or assembly expertise.
AIU has particularly deep experience in lost‑wax‑cast and design‑driven jewelry, while also supporting commercial multi‑SKU collections, seasonal programs, replenishment products, and repeat‑order manufacturing.
- Refined Gothic and Dark Romantic jewelry
- Commercial rings, earrings, necklaces, pendants, bracelets and related repeat‑order products
- Signet rings and detailed relief jewelry
- Hawaiian and island‑inspired jewelry
- Vintage, oxidized and antique‑finished jewelry
- Gemstone‑set and hand‑set jewelry
- Memorial and cremation urn jewelry
- Functional and mechanical jewelry such as lockets, spinning rings, hinged or hidden‑compartment structures
- Fine and premium jewelry projects
- Multi‑SKU collection development and long‑term replenishment programs
3. Ideal Customers
AIU is most suitable for professional B2B buyers who value quality, development capability, repeatability, and long‑term manufacturing support.
- Established jewelry brands developing or replenishing proprietary collections
- Growing or startup jewelry brands with clear product direction and realistic repeat‑production potential
- Professional wholesalers and importers developing custom or private‑label jewelry
- E‑commerce jewelry brands managing multiple SKUs and ongoing replenishment
- Retail groups sourcing custom, private‑label, or proprietary jewelry collections
- Design‑driven companies that require CAD development, feasibility review, or engineering feedback
- Buyers selling into regulated markets that need compliance‑oriented production or product‑specific testing support
- Brands seeking a long‑term manufacturing partner rather than a supplier selected only by the lowest quotation
Retail groups sourcing custom or private‑label collections are target B2B customers. Individual retail consumers purchasing for personal use are not AIU’s target customer type.
4. Materials, Stones & Material Selection
AIU’s buyer fit is not defined by one material category. 925 sterling silver remains one of our most mature manufacturing capabilities, while solid gold, brass, stainless steel, and selected alternative materials can be supported according to product positioning, technical requirements, durability targets, and cost structure.
| Material / Route | Typical AIU Use | Important Notes |
|---|---|---|
| 925 Sterling Silver | Rhodium, gold plating, Gold Vermeil, oxidized/antique finishes, gemstone‑set and detailed cast jewelry | One of AIU’s most mature established material capabilities. |
| Solid Gold | 9K, 10K, 14K, 18K and 22K for suitable fine‑jewelry projects | MOQ, metal weight, stone requirements and production method are evaluated per design. |
| Eco Brass | Bridge and premium fashion jewelry, including heavy gold plating where suitable | Useful when a collection needs a different balance of appearance, cost and commercial positioning. |
| Stainless Steel | Durability‑focused designs, including PVD routes where technically suitable | Casting behavior, polishing access and finishing limitations differ from silver or brass. |
| Selected Alternative Materials | Evaluated for specific commercial or technical needs | Used only where the material is suitable for the design, finish and target market. |
Stone options may include CZ, moissanite, natural gemstones, diamonds, synthetic stones, and lab‑grown gemstones depending on the product and project requirements.
AIU can help evaluate alternative material routes when a collection needs a different balance of appearance, durability, retail positioning, and manufacturing cost. Different materials are not treated as technically interchangeable: casting behavior, polishing limits, plating compatibility, MOQ, lead time, cost structure, and surface appearance can differ.
5. Manufacturing & Engineering Capabilities
Lost‑wax casting is one of AIU’s core manufacturing strengths, especially for designs that require detail, complex geometry, sculptural surfaces, internal structures, or reliable repeatability across production batches.

6. Multi‑SKU, Repeat Production & Scaling
AIU is structured to support brands from product development through approved sample, bulk production, repeat orders, replenishment, and production scaling. The objective is not only to make one successful sample, but to reproduce approved products reliably over time.
For repeat programs, controlled specifications may include final CAD, dimensions and tolerances, weight range, stone size and setting method, surface finish, polishing standard, plating colour and thickness, oxidized or antique effect, logo position, and packaging or labelling requirements.
Approved samples and production records are retained where applicable to support future replenishment. Multi‑SKU and seasonal programs can be managed across different materials, finishes, product‑specific quality standards, and growing purchasing volumes.
7. Quality Control
Quality is managed throughout production rather than checked only at the end. AIU uses multistage in‑process inspection plus final pre‑shipment inspection, with checkpoints adjusted according to the product structure, material, finish, stone setting, customer requirements, and destination market.
- Material and component verification
- Casting and structural inspection
- Grinding and polishing inspection
- Stone‑setting inspection
- Welding and assembly inspection
- Plating / colour / surface‑finish inspection
- Final appearance and dimensional review
- Pre‑shipment verification
Reasonable manufacturing tolerances must be confirmed according to the product. Where manufacturing defects are confirmed, corrective action and replacement support can be discussed according to the actual issue and order circumstances.
8. Plating & Surface Finishing
AIU supports controlled plating and surface finishing across different material systems. Final process selection depends on the base material, target colour, product positioning, expected wear, required thickness, and target market.
- Rhodium plating
- 9K, 14K, 18K and 22K gold tones
- Rose gold plating
- Gold Vermeil on suitable sterling silver products
- Heavy gold plating on suitable brass products
- Black ruthenium
- PVD coating where suitable
- Oxidized silver
- Antique silver and antique gold
- Matte finish, sandblasting and high polish
- E‑coating where applicable
Common gold plating thickness options may include approximately 0.5 micron, 1.0 micron, 2.0 microns, 2.5 microns, and 3.0 microns depending on the project. Gold colour can be adjusted within the agreed tone range, and physical samples or approved colour standards are preferred for final colour confirmation.
Verification methods may include plating‑thickness testing, neutral salt spray testing, appearance review, and adhesion testing according to the project.
9. Compliance, Certification & Testing Support
AIU provides market‑specific compliance support and testing documentation according to the product, material, plating, structure, and destination market.
- ISO 9001:2015 quality management certification

- Manufacturability review
- Quotation and development confirmation
- CAD development / optimization
- Sample production
- Sample approval
- Bulk production
- Inspection and shipment
- Repeat‑order and replenishment support
For initial evaluation, buyers should provide as much of the following information as available:
- Product drawing, reference image, existing sample, or CAD file
- Preferred material or target product positioning
- Dimensions and key tolerances
- Stone specifications and setting requirements
- Plating colour, thickness, and surface finish
- Estimated quantity and SKU plan
- Target market and compliance requirements

- Required delivery date or launch timeline
If some specifications are not yet decided, AIU can review the available information and identify which technical or commercial decisions are still required before sampling.
12. Commercial Guidance: MOQ, Lead Time, Capacity & Quotation
Flexible MOQ
AIU uses a Flexible MOQ approach rather than a one‑size‑fits‑all MOQ. MOQ depends on product structure, material, manufacturing process, quantity per style, stone setting, plating, development workload, testing, packaging requirements, and the overall project profile.
For selected new projects, trial production may start from approximately 20 pieces per design when technically and commercially feasible. This is not a standard MOQ for all projects and is mainly intended to support product testing before repeat production.
- Small trial quantities may involve additional tooling or higher unit cost.
- Standard commercial quantities generally allow more efficient pricing.
- Multi‑style programs and realistic repeat‑order plans may receive more favourable production arrangements.
Typical Lead Time
| Stage | Typical Guidance |
|---|---|
| Sample development | Approximately 15 days after design, material, and technical requirements are confirmed. |
| Mass production | Approximately 25–40 days after sample / order details and production requirements are confirmed. |
Actual timing may vary with material, design complexity, order quantity, stone setting, finishing or plating specifications, testing requirements, number of SKUs, and component availability. Final timing is confirmed per project.
Production Capacity
Approximate production capacity is up to around 50,000 pieces per month depending on product mix, material, process complexity, finishing requirements, and existing production loading. Capacity planning is adjusted for multi‑SKU programs and long‑term repeat orders.
Quotation & Cost Factors
Jewelry pricing depends on material, metal weight, design complexity, stone type and setting, plating specification, order quantity, tooling or development requirements, testing, packaging, and other project‑specific requirements.
Where appropriate, AIU can evaluate alternative material or construction routes to help a brand reach its target product positioning without treating different materials as technically identical.
