Chilean Client’s Batch Customization of 925 Silver Rose Gold-Plated Necklaces at JINGYING Jewelry: A Technical and Cultural Case Study

1. Introduction: The Allure of Rose Gold in Chile’s Jewelry Market

Chile, a nation where the Andes Mountains meet the Pacific Ocean, has cultivated a unique jewelry aesthetic blending indigenous Mapuche influences with modern luxury. In 2023, rose gold emerged as Chile’s fastest-growing jewelry category, capturing 41% of the precious metal market (Cámara Nacional de Comercio de Chile). This 5,000-word case study explores how JINGYING Jewelry Company partnered with a Santiago-based retailer to produce 7,500 units of 925 silver necklaces with rose gold plating, merging Chilean cultural motifs with industrial precision. The project demonstrates how technical innovation and cultural sensitivity can unlock opportunities in Latin America’s most stable economy.

2. Market Context: Chile’s Evolving Jewelry Landscape

2.1 Consumer Preferences (2023 Data)

• Design Trends:
  • 65% favor geometric patterns inspired by aukas (traditional Mapuche symbols)
  • Chain lengths: 50-60cm for layering over high-neck clothing
• Material Demands:
  • 925 silver dominates 58% of mid-range market
  • Rose gold plating thickness expectation: 2.5-3μm

2.2 Regulatory Environment

• INN Certification: Mandatory for precious metal imports (NCh 3248)
• Chilean Nickel Regulation: <0.1μg/cm²/week release limit

3. Client Profile & Design Specifications

3.1 Client Background

• Retailer: Santiago chain with 18 stores nationwide
