Jewelry Certification Guide: Why You Should Know
Jewelry Certification
Certifications play a crucial role in the jewelry industry as they guarantee product quality and safety by ensuring products are free from toxic substances that may cause allergic reactions. They create transparency in manufacturing processes, allowing consumers to know the origin of raw materials and production standards. Certifications protect labor and social rights by ensuring fair wages and prohibiting child labor, promote environmental conservation through the use of sustainable materials and waste reduction, increase business value and credibility that facilitate easier access to international markets, and reduce legal risks from non-compliance with safety regulations and labor rights. Having certifications therefore guarantees that the jewelry produced and sold is of high quality, safe, and manufactured through ethical processes.

Business Social Compliance Initiative (BSCI)
The Business Social Compliance Initiative (BSCI) is a tool established in 2003 that companies use to help improve working conditions throughout their supply chains. It focuses on international labor rights conventions, and businesses participating in the BSCI program should establish a shared code of conduct to help ensure these ethical business practices are implemented.
When implementing BSCI, businesses that adopt this process agree to comply with the following 11 principles:
- Right of freedom of association and collective bargaining
- No discrimination
- Fair remuneration
- Decent working hours
- Occupational health and safety
- No child labor
- Protection of young workers
- No precarious employment
- No bonded labor
- Protection of the environment
- Ethical business behavior

Responsible Jewellery Council
The RJC is an international non-profit organization that leads in creating production standards for gems and jewelry throughout the supply chain, from mines to retail businesses, with consideration for social and environmental responsibility. It emphasizes ethics in the gems and jewelry industry, focusing on human rights and workers’ rights, particularly in the luxury jewelry market. The RJC issues standard certifications to members to establish internationally recognized and accepted standards.
Code of Practices is broadly divided into 6 categories for companies
- To improve legal and regulatory compliance, strengthen public reporting and secure a commitment to responsible business practices.
- To increase the use of due diligence in supply chains to uphold human rights, support community development, promote anti-corruption efforts and manage sourcing risks.
- To better comply with international labour conventions and ensure responsible working conditions.
- To protect the health and safety of both people and environments, and to use natural resources efficiently.
- To adequately control, and disclose information about, products and so avoid misleading or deceptive marketing practices.
- To secure responsible exploration and mining practices that protect potentially affected communities and environments from adverse impacts.

SEDEX
Supplier Ethical Data Exchange is a non-profit organization that operates a collaborative platform for sharing ethical supply chain data. Being a SEDEX-certified company means that the organization has undergone an assessment process and complies with certain standards related to responsible and ethical business operations within the supply chain. SEDEX is not a direct certification body, but rather a platform where companies can share and manage information about their supply chain practices.
SEDEX itself does not provide certifications or score suppliers, nor is it a company that audits ethical operations, and it is not an organization that issues certifications to businesses. Being certified means that the company or organization has passed an assessment of ethical and social compliance practices, focusing on four main pillars:
- Labor Standards: Ensuring fair and safe working conditions for employees, including fair wages, reasonable working hours, and adherence to labor laws.
- Health and Safety: Implementing measures to protect workers’ health and safety, providing a safe working environment, and preventing accidents and injuries.
- Environment: Encouraging sustainable practices, minimizing environmental impact, and complying with relevant environmental regulations.
- Business Ethics: Upholding ethical business practices, including transparency, integrity, and compliance with laws and regulations.

ISO 45001

ISO 9001:2015
This is a Quality Management System (QMS) standard that can be applied to any organization, regardless of which industry they operate in, including the jewelry industry. An example of role division according to the ISO 9001:2015 standard might involve dividing responsibilities into two main groups: first, supervisors or managers in charge of work operations, and second, supervisors or managers in charge of buildings and facilities. After that, further subdivision follows according to positions that receive responsibility in various areas.

ISO 14001
ISO 14001 is an internationally recognized Environmental Management System (EMS) standard. This standard helps organizations, whether small or large, to effectively manage and control environmental impacts arising from the organization’s activities, services, and products.

New York State Regulates Lead in Children’s Jewelry
On December 16, 2019, the Governor of New York signed Assembly Bill A6041 (S4046) to regulate lead content in children’s jewelry. This new law contains several important provisions, including:
- Defining children as those under 12 years of age
- Providing a definition of jewelry
- Requiring warning labels on children’s jewelry or on the packaging container if lead content exceeds 40 ppm but is below 600 ppm, or meets lower federal government standards – this warning is not necessary if components are exempted from third-party testing as specified by the US Consumer Product Safety Commission (US CPSC)
