Supply Chain Policy


IGCJD does not source from conflict-affected and high risk areas, nor from artisanal and small-scale minng.


IGCJD deals with polished untreated diamonds of natural origin only and therefore works only with suppliers providing full disclosure in the sale and distribution of their products. IGCJD is not involved in the production, manufacturing and trade of Lab-grown Diamonds, Treated Diamonds and simulants

IGCJD deals only in diamonds that have been purchased from legitimate sources not involved in funding conflict, and in compliance with United Nations resolutions. IGCJD adheres strictly to all rules and requirements of the World Diamond Council System of Warranties (SoW) .

As per the World Diamond Council SoW, the following clause is required on every incoming and outgoing invoice or memo:

“The diamonds herein invoiced or on memo are exclusively of natural origin and untreated based on personal knowledge and/or written guarantees provided by the supplier of these diamonds.”


IGCJD ‘s employees need to know what are Lab-Grown Diamonds, Treated Diamonds, and Simulants (LTS). In case IGCJD would sell any LTS, it would need to be disclosed before the sales transaction takes place, as well as as on all documents related to the transaction. It must be disclosed up to end- consumer level.


IGCJD sources the majority of its diamonds from the De Beers Sightholder company IGC New York Inc. (, which is also a Certified RJC Member. The risk of contamination is therefore very small. In case of sporadic procurement form third parties on the market, IGCJD requires full transparency and disclosure from its vendors.


Across its global supply chain, IGCJD observes the highest ethical standards and requires from its business partners the same. This extends to sourcing of gold and platinum.

IGCJD works to

  • ensure that its gold and metals come from suppliers that meet the highest human rights, social, and environmental criteria.
  • engage suppliers to influence the sourcing of gold products.
  • give preference to suppliers that source gold from mines that observe high standards of environmental responsibility

IGCJD views its policy on responsible sourcing as an evolving standard. It commits to continuously review its position with the goal of expanding it over time to have the broadest possible impact.

IGCJD undertakes a risk-based due diligence, which entails a reasonable investigation to identify, assess, prevent and mitigate risks in its supply chain where the level of supply chain scrutiny is commensurate with the identification of risks.

Within this investigation process, IGCJD will aim to identify potential red flags. A red flag is a warning or indicator of a potential risk, which can refer to a location, supplier or circumstance. If a red flag is identified, IGCJD will proceed with enhanced due diligence or further investigation.

IGCJD works together with an external compliance officer to perform the due diligence process. Regular review and reporting is done, at least annually.

IGCJD only uses materials that are suitable for retail jewelry according to the California Proposition 65 jewelry-making materials classification, including karat gold and platinum

IGCJD performs its due diligence for both supply chain and customer base with a dedicated external compliance officer. A detailed description of the process and tools can be found in IGDJD’s AML Policy and Procedures.

IGCJD requests from its suppliers the same level of due diligence regarding their supply chains and regular communication about it.


IGCJD offers all parties (affected stakeholders or whistle-blowers) a way to raise concerns about the businesses, organisations, individuals or activities in its supply chain. This grievance mechanism serves as a tool for identifying and reacting to issues in the supply chain that may otherwise go unnoticed.

For details on the griievance mechanism, we refer to our separate Grievance Policy. IGCJD annually reports to its BoD any red flags or concerns that may have arised during its due diligence process for responsible supply chains of diamonds, gold, and platinum.


IGCJD seeks to support the social, economic, and institurional development of the communities in which it operates and supports community initiatives.
