1. Introduction to Openwork Jewelry

Openwork (or filigree) jewelry features intricate cut-out designs, making it lightweight yet visually striking. A rose-shaped pendant in this style requires precision manufacturing, typically using:
✔ CNC machining (for sharp, clean edges)
✔ Laser cutting (for delicate patterns)
✔ Casting de inversión (for organic shapes)

This guide covers how to produce an openwork rose pendant and analyzes cost factors based on materials, mano de obra, and order quantity.

2. Designing the Rose-Shaped Pendant

Key Design Considerations

  • Pattern Complexity (more details = higher cost)

  • Tamaño & Espesor (affects material usage)

  • Attachment Method (bail, jump ring, or integrated chain)

Software Used

  • CANALLA (Rhino, Matrix, ZBrush) for 3D modeling

  • Vector (Adobe Illustrator) for laser-cut designs

Example Design Specs:

  • Diameter: 25mm

  • Espesor: 1.2mm

  • Material: 925 Plata esterlina

3. Materials Selection

Material Pros Cons Mejor para
925 Plata esterlina Premium finish, resistente a la deslizamiento Higher cost High-end jewelry
Brass (Gold-Plated) Asequible, versatile May tarnish over time Fashion jewelry
Stainless Steel Durable, hypoallergenic Harder to cut finely Diseños minimalistas

4. Manufacturing Methods

4.1 CNC Machining

  • Proceso: A computer-controlled router cuts the design from a metal sheet.

  • Mejor para: Precise geometric patterns.

  • Cost: $8–$20 per unit (Moq 50+)

4.2 Corte con láser

  • Proceso: A laser burns through metal to create intricate designs.

  • Mejor para: Ultra-fine details (P.EJ., petal textures).

  • Cost: $5–$15 per unit (Moq 100+)

4.3 Fundición (Lost-Wax & 3D impresión)

  • Proceso: Wax model → Plaster mold → Molten metal casting.

  • Mejor para: Organic, curved rose shapes.

  • Cost: $10–$30 per unit (Moq 20+)

4.4 Fabricación de manos

  • Proceso: Artisans cut and solder metal wires.

  • Mejor para: Custom one-of-a-kind pieces.

  • Cost: $50–$200 per unit (Labor-intensive)

5. Step-by-Step Production Process

Paso 1: Diseño CAD & Prototipos

  • Create a 3D model of the rose pendant.

  • Test print in wax or resin before metal production.

Paso 2: Metal Cutting/Forming

  • CNC/laser cuts the design from a sterling silver sheet.

  • If casting, inject molten silver into a mold.

Paso 3: Limpieza & Pulido

  • Remove burrs with ultrasonic cleaning.

  • Polish to a mirror or matte finish.

Paso 4: Enchapado (Opcional)

  • Gold/Rhodium plating for extra shine.

  • Antique oxidation for vintage effects.

Paso 5: Inspección de calidad

  • Check for defects, weight, and dimensions.

  • Test plating durability (salt spray test).

6. Refinamiento & Plating Options

Finish Effect Cost Addition
Alto esmalte Mirror-like shine +$1–$3
Matte/Satin Soft, non-reflective +$2–$5
Recubrimiento de oro Luxe rose gold/yellow gold +$3–$10
Oxidized Darkened vintage look +$4–$8

7. Control de calidad & Testing

  • Precisión dimensional (caliper measurement)

  • Plating Adhesion Test (tape peel test)

  • Resistencia al deslizamiento (humidity chamber)

8. Cost Breakdown

A. Material Costs

Material Cost per Unit
925 Plata (25mm) $6–$15
Brass (Gold-Plated) $3–$8
Stainless Steel $4–$10

B. Labor & Production Costs

Method Cost per Unit
CNC Machining $8–$20
Corte con láser $5–$15
Fundición $10–$30
Handmade $50–$200

C. MOQ Impact on Pricing

Order Quantity Price per Unit
1–50 pcs $25–$80
50–200 pcs $15–$40
200–1000 pcs $8–$25
1000+ pcs $5–$15

Total Estimated Cost Range:

  • Mass Production (1000+): $10–$25/unit

  • Small Batch (50–100): $20–$50/unit

  • Custom Handmade: $80–$300/unit

9. OEM vs. ODM Production

  • OEM: You provide the design; factory produces it.

  • ODM: Factory designs & manufactures for you.

Best Choice?

  • Startups → ODM (lower design cost)

  • Established brands → OEM (full customization)

10. Top Manufacturers

  1. Porcelana: Low-cost, high-volume (Moq 500+)

  2. Thailand: Handcrafted excellence (Moq 50+)

  3. Italia: Luxury craftsmanship (Moq 10+)

11. Case Study: 500-Unit Production Run

  • Diseño: Laser-cut sterling silver rose pendant

  • Fabricante: Guangdong Jewelry Co. (Porcelana)

  • Cost: $12/unit ($6,000 total)

  • Timeline: 25 días (including shipping)

12. Conclusión & Recommendations

  • Best for Budget: Laser-cut brass (gold-plated)

  • Best for Luxury: CNC-milled 925 plata

  • Best for Small Batches: Fundición + hand-finishing

Next Steps:

  1. Finalize CAD design (or use ODM catalogs).

  2. Request quotes from 3–5 manufacturers.

  3. Order samples before full production.
