If you are looking for a reliable stainless steel jewelry manufacturer or OEM jewelry factory,

this FAQ page answers the most common questions about materials, MOQ, pricing, plating, quality control, compliance, and global shipping.

General

1. What materials do you use in your jewelry manufacturing?

We specialize in multi-material hybrid craftsmanship, providing ideal material combinations for global brands:

  • Metals: 316L medical-grade stainless steel, Eco-Brass, zinc alloy, titanium, tungsten steel.
  • Non-metals: Genuine leather, acrylic, resin, wood, ceramic.
  • Gemstones & Setting: Expertise in hand-set micro-pavé techniques for semi-precious stones (agate, mother-of-pearl, tiger’s eye), crystals, pearls, and zirconia.
  • Others: Sterling silver (925), pure copper.

Note: All materials comply with EU REACH and US CA Prop 65 regulations. Lead, cadmium, and nickel release tests are conducted to meet international jewelry safety standards.

2. What is your MOQ for custom jewelry manufacturing?

We offer flexible MOQs to support brands’ seamless transition from development to mass production:

  1. Regular designs: 30 pieces/pairs per style per color.
  2. Complex craftsmanship/custom molded styles: 200-500 pieces minimum (depending on complexity).
  3. Existing standard molds/stock components: 30 pieces/pairs minimum.
  4. Sample orders: 1 piece available.
  5. Advantage: Flexible MOQs ranging from 30 to 120 pieces to support brands in market testing.

3. How much does OEM jewelry production cost?

As an SGS-audited factory, we deliver high cost-effectiveness through optimized supply chains. Pricing depends on materials, processes, plating, and quantity, typically ranging from $1 to $100.We will provide you with a free detailed quote—all we need is your design drawings, dimensions, and quantity.

4. Do you provide jewelry samples before bulk production?

Yes.We encourage pre-production samples to confirm quality.

  • Existing Styles: One sample available at material cost + shipping (approximately ¥50–¥200), refundable upon bulk order placement.
  • Custom Samples: Produced per drawings, subject to a prototyping fee (¥500-¥2000). Refundable upon reaching specified bulk order quantities.
  • Lead Time: Existing samples ship within 2-3 days; custom samples require 7-15 days (including communication and confirmation).

5. What is your production lead time?

Leveraging our stable team and mature processes, we ensure reliable delivery:

  1. Standard Orders: Shipment within 20-30 days after payment confirmation.
  2. Complex Processes/Large Volumes: 30-60 days.
  3. Expedited Service: Can be shortened to 10-18 days (An additional 30% rush fee will be charged).
  4. Advantages: Standard lead time of approximately 25 days. Our team excels in customs clearance and maintains stable partnerships with UPS/FedEx for seamless global delivery.

6. What plating options do you offer?

To address fading concerns, we apply material-specific protective technologies:

  • Coating thickness: Standard 0.03μ – 0.05μ; upgradable to 0.1μ.
  • Color options: 14K/18K gold, white gold, rose gold, antique silver, gun black, brushed/matte finish.
  • Anti-rust technology:
    (1) Stainless steel: Utilizes PVD vacuum plating (0.03-0.1μm), passing 48-hour salt spray testing.
    (2) Copper/Alloy: Features a professional electrophoretic coating (E-Coating) over genuine gold plating (0.03-3μm), forming an “invisible barrier” against oxidation.
  • Safety: All skin-contact layers pass nickel release testing, meeting European and American standards.

7. How do you control quality in bulk production?

We firmly believe that “consistent quality secures the future” and implement comprehensive quality control throughout the entire process:

  1. Incoming Material Inspection: Random sampling of all metal/stone components.
  2. Initial Production Inspection: Confirmation of the first piece from each batch.
  3. In-Process Inspection: 100% self-inspection by dedicated personnel at critical stages (e.g., hand-setting) to ensure no risk of gemstone detachment.
  4. Final Product Inspection: Comprehensive checks on functionality, appearance, plating adhesion, and gemstone security.
  5. Pre-shipment Sampling: An independent QC team of 8-12 inspectors enforces AQL standards, strictly controlling defect rates below 1%.
    Third-party inspection services available (client-funded).

8. Do you offer OEM and ODM jewelry services?

Comprehensive OEM/ODM support from concept to mass production:

  • Design Customization: Create designs from provided sketches/samples with free 3D revisions until satisfaction. Specialize in innovative combinations of leather, acrylic, and metal.
  • Logo Customization: Laser engraving, mold embossing, or resin-filled logos.
  • Packaging Customization: Velvet pouches, jewelry boxes, and cards with brand information printing.
  • Personalized Engraving: Supports date/name/message engraving.
