Sustainability in the Supply Chain

In TASAKI’s materials procurement, as well as ensuring quality, we place importance on sustainability perspectives, including compliance with laws and regulations, prevention of corruption, health and safety in labor environments, and protection of the environment.

We also work with suppliers and pursue initiatives that will lead to the growth of the industry as a whole.

Sustainability Initiatives in the Supply Chain

Procurement rules and procedures

Under our procurement rules, TASAKI stipulates detailed conditions for the procurement of materials, emphasizing that our business partners must be able to provide a stable supply of quality materials and have an excellent track record and reliability.

For new transactions, our buyers first select business partner candidates according to the conditions stated in our procurement rules and obtain the approval of the executive director in charge before beginning trading with the new business partners.

Clean diamonds

TASAKI works exclusively with trusted suppliers who meet our rigorous procurement standards. The diamonds we handle are sourced with careful consideration for labour conditions, environmental protection, anti-corruption measures, and responsible business practices.

Identification of diamonds

TASAKI has a policy of handling only natural diamonds, but in this industry, it is not uncommon for synthetic diamonds (known as laboratory grown diamonds.) to become mixed up with natural diamonds accidentally in the course of trading.

TASAKI employs the latest equipment and third-party appraisers to distinguish between synthetic and natural diamonds both at the point of shipment from the business partner’s side and on delivery to TASAKI.

Through this process, TASAKI maintains our targeted quality standard and also contributes to increasing the credibility of the industry as a whole.

Sharing our accumulated knowledge and technologies with the industry and in industry-academia-government collaborations

TASAKI shares with other pearl farmers the knowledge that we have accumulated in our many years of operating our own pearl farms, as well as baby oysters with pedigrees that have lower rates of necrosis, produced by joint research, including participation in industry-academia-government projects on artificial spat production. In these and other ways, we are working to ensure the stability and growth of the pearl farming industry.＊1
