The Future of Fine Jewelry: A Framework for Transparent and Sustainable Supply Chains

1 Introduction:

Sustainable Development Challenges and the Need for Industry Transformation

In the context of global climate change and resource scarcity, sustainable development has become a core issue across industries—including the high jewelry sector. As an industry characterized by luxury and resource intensity, high-end jewelry faces unprecedented environmental and social responsibility challenges. In recent years, consumer demand for product transparency has surged, particularly among millennials and Gen Z, who value not only aesthetic appeal but also the ethical narratives and environmental footprint behind their purchases.

The high jewelry industry relies on rare materials like gold, diamonds, and colored gemstones, often sourced through complex and fragmented global supply chains. From artisanal mines in remote regions to international trading hubs and retail networks, each link presents potential transparency and traceability issues. This is especially true for colored gemstones, which depend heavily on artisanal and small-scale mining (ASM), involving an estimated 30 million workers across 47 countries, including 2 million children.

While frameworks like the Kimberley Process Certification Scheme offer some protection, they often fall short in addressing systemic issues such as human rights violations, worker exploitation, and environmental degradation. There is a clear and urgent need for innovative, practical solutions to enhance traceability.

This paper, based on doctoral research from the Polytechnic University of Milan, examines these challenges through mixed-method research and proposes a groundbreaking framework aimed at transitioning the industry from a linear to a circular economy—while meeting rising consumer and regulatory expectations. For companies like JewelryBuyDirect, a forward-thinking fashion accessory and jewelry wholesaler, adopting such frameworks is essential to aligning with modern values and market demands.

2 Research Framework and Methodology

2.1 Theoretical Basis and Conceptual Framework

This study integrates Circular Economy principles, the Environmental, Social, and Governance (ESG) framework, and the UN Sustainable Development Goals (SDGs). The circular model emphasizes resource efficiency, extended product life cycles, and value creation through reuse and recycling—fundamental to reimagining the jewelry value chain.

Regulatory drivers like the EU’s Corporate Sustainability Reporting Directive (CSRD) and Corporate Sustainability Due Diligence Directive (CSDDD) further shape this research, requiring businesses to report on sustainability performance and conduct supply chain due diligence. The CSDDD’s “double materiality” principle mandates that companies assess both their impact on society and the financial implications of sustainability issues.

Eco-design principles also play a key role, urging designers to consider a product’s entire lifecycle—from material sourcing and manufacturing to usage and end-of-life recycling. This shift is crucial for an industry traditionally focused on aesthetics and scarcity over environmental impact.

2.2 Research Methodology

A Mixed Methods Research approach was used, combining qualitative and quantitative analyses. The research unfolded in four phases:

• Literature review of academic, industry, and conference publications
• Data collection via expert interviews and case studies with professionals in sustainability, jewelry design, and mining
• Validation through a 6-month internship with Bulgari’s corporate social responsibility team
• Reflective analysis and future goal-setting, supported by research collaborations with the Rochester Institute of Technology and Stanford University

This methodology enabled a 360-degree view of supply chain traceability challenges and technological opportunities.

3 Sustainability Challenges in the High Jewelry Industry

3.1 Environmental Challenges and Resource Scarcity

High jewelry depends on non-renewable resources—precious metals and gemstones—that take millions of years to form. Extraction rates vastly exceed natural renewal, depleting high-quality deposits and increasing mining costs and complexities.

Gold mining is notably destructive, often involving cyanide leaching, deforestation, soil erosion, and water pollution. Producing one ounce of gold requires processing approximately 250 tons of ore. Diamond mining also carries a heavy environmental footprint due to energy and water intensity, while colored gemstone mining frequently occurs in ecologically sensitive zones with poor oversight, leading to irreversible ecosystem damage.

3.2 Social and Ethical Challenges

Approximately 90% of the global mining workforce is within artisanal and small-scale mining (ASM), where conditions are often hazardous and unregulated. Child labor remains rampant, with over a million children engaged in dangerous mining activities, often sacrificing education and health for minimal pay.

Mercury pollution from small-scale gold mining accounts for 37% of global anthropogenic mercury emissions, posing severe public health risks. Additionally, mining frequently triggers community conflicts and land rights disputes, especially within indigenous territories.

3.3 Supply Chain Complexity and Lack of Transparency

The journey from mine to market involves numerous intermediaries—miners, cutters, traders, manufacturers, and retailers—each potentially obscuring information. Colored gemstone supply chains are especially fragmented, lacking uniform standards. Gems may pass through multiple hands and regions, sometimes intentionally obscuring origins to bypass regulations or inflate prices.

Information asymmetry is common; upstream actors possess origin details rarely communicated downstream. Certification systems like Fairmined and Fairtrade remain limited, particularly for colored stones, and are difficult to scale across ASM contexts.

4 Technological Innovations and Solutions

4.1 Identification Technologies and Tracking Systems

QR codes, RFID, and NFC technologies enable basic to advanced traceability. QR codes offer cost-effective, smartphone-readable product insights but lack real-time tracking. RFID allows non-line-of-sight, high-volume scanning, while NFC supports secure short-range communication—ideal for access control and payment integration.

NFTs (Non-Fungible Tokens) provide blockchain-based proof of ownership and authenticity, creating immutable digital records for physical jewelry items.

4.2 The Revolutionary Potential of Blockchain Technology

Blockchain’s decentralized, tamper-proof ledger system is ideal for documenting each transaction from mine to consumer. Data such as origin, weight, certification, and ethical credentials can be securely recorded and shared. Industry pioneers include:

• Everledger: diamond and gemstone traceability
• De Beers’ Tracr: blockchain-based diamond tracking
• Aura Blockchain Consortium: founded by LVMH, Prada, Cartier, and others, delivering unified luxury sector solutions

4.3 Innovative Application of Digital Product Passport

The Digital Product Passport (DPP), a cornerstone of the EU’s Circular Economy Action Plan, will likely become mandatory by 2030. In jewelry, DPP takes the form of a Digital Jewelry Passport (DJP)—accessible via QR or NFC—containing information about materials, manufacturing, environmental impact, and lifecycle. Brands like Bulgari, Dior, and Tiffany are already piloting DJPs, which also facilitate resale, recycling, and repairs.

4.4 Application of Artificial Intelligence and Laser Technology

AI optimizes supply chain management and risk assessment, analyzing data to identify vulnerabilities and improve decision-making. Companies like KoBold Metals use AI for mineral exploration, while Rio Tinto employs it to enhance safety and sustainability.

Laser technology enables permanent gemstone marking without affecting clarity. Opsydia’s subsurface laser inscriptions and ALROSA’s nano-marking allow secure, undetectable identification complementary to blockchain traceability.

5 Implementation Guidance and Strategic Framework

5.1 Comprehensive Traceability Management System

Companies should adopt the OECD’s five-step due diligence framework:

1. Establish strong management systems and supply chain policies
2. Identify and assess risks (e.g., human rights abuses, fraud)
3. Develop and implement risk response strategies
4. Conduct third-party audits
5. Publicly report on due diligence efforts

5.2 Implement Traceability Gradually Through Pilot Projects

Begin with controlled pilot projects using a “country-by-country, supplier-by-supplier, gemstone-by-gemstone” approach. Steps include selection, research, field visits, and reporting to understand sourcing realities and establish best practices.

5.3 Using AI for Supplier Risk Assessment

Leverage AI to collect and analyze supplier data—assessing financial, geopolitical, environmental, and ethical risks—enabling diversification and proactive management. AI supports continuous monitoring and real-time risk updates.

5.4 Integrate Technological Innovation with Business Processes

Invest in technology infrastructure, employee training, and organizational redesign to embed innovations like blockchain, AI, and DPPs. Collaborate with tech providers, academia, and industry consortia to accelerate learning and implementation.
