Our responsible sourcing policy

Our responsible sourcing policy

At Mikimoto, we adhere to transparent and ethical business practices, with a strong commitment to respecting human rights and labour rights as well as minimizing environmental impact. And importantly, we remain steadfast in our commitment to ethical sourcing throughout our global supply chains.

Mikimoto guarantees that all our diamonds are conflict-free. Conflict diamonds are mined in war zones in African countries and sold to fund military action against governments. The Kimberley Process Certification Scheme was established in 2003 to put an end to the conflict diamond trade, and now you need a certificate issued by the country of origin to export or import rough diamonds. All participating countries must adhere to the System of Warranties that requires suppliers to provide warranty statements on all sales and purchase invoices for diamonds. We adhere rigorously to both the Kimberley Process and the World Diamond Council's voluntary System of Warranties.

The same goes for our gold. All the gold we use is from refiners accredited by the London Bullion Market Association (LBMA) to avoid contributing to conflict and human rights abuses. The LBMA is a London-based international trade association representing the global wholesale gold and silver market and responsible for maintaining benchmarks for all precious metals. It also accredits auditors and assurance providers to enable them to conduct Responsible Gold Audits. By trading with the most trusted and reliable suppliers, we ensure the quality and integrity of our gold.

In August 2021, Mikimoto became a member of the Responsible Jewellery Council (RJC). We are preparing to achieve certification against the RJC’s Code of Practice (COP). The RJC, an international not-for-profit organization founded in 2005, is the leading standards-setting and certification body for the global jewellery and watch industry. It has more than 1,500 member companies that span the entire supply chain, from mine to retail.

Zero-emission pearl farming

Zero-emission pearl farming

Pearl oysters need a thriving marine ecosystem that offers nutrients and water quality for healthy growth. We are taking steps to reach net-zero emissions by developing responsible pearl farming standards and technological solutions to protect the natural environment. This will help us produce pearls in a more ecologically sustainable manner. In the past, when pearls were harvested, the shells and meat were discarded, except for the adductor muscle that was eaten as food. In collaboration with our internal and external partners, we are reusing and recycling all the waste that results from the process of pearl production.
For example, we extract active ingredients, such as collagen and conchiolin, which is known as pearl protein, from organic waste and use them in cosmetics and food supplements. Shells are used to make ornaments or improve soil quality. The residue of oyster meat and fouling organisms on the pearl oysters are used to make compost.

Sustaining the ocean's ecosystems as a prerequisite to producing beautiful pearls

Mikimoto not only conducts its own research on pearls but also supports marine scientists and researchers.

The Mikimoto Charitable Trust for Marine Ecology Research

The Mikimoto Charitable Trust for Marine Ecology Research

Established in July 1992, the trust has been supporting scientists and research teams who research species that live in intertidal zones, areas that are above water at low tide and underwater at high tide. It aims to help develop creative ways to protect and sustain marine biodiversity and ecosystems.

The Mikimoto-Morse Scholarship

The Mikimoto-Morse Scholarship

The Mikimoto-Morse Scholarship was named in honor of American zoologist and Orientalist Dr. Edward Sylvester Morse and our founder, Kokichi Mikimoto. Dr. Morse discovered the Omori Shell Mounds and contributed to establishing the University of Tokyo’s Misaki Marine Biological Station. The scholarship was established in 2013 to encourage cooperation and cultural exchange between young scholars in Japan and the USA and foster the advancement of ocean science and marine studies.
It is open to students and scientists at Friday Harbor Laboratories (University of Washington) and the Graduate School of Science at the University of Tokyo, which also hosts a satellite office of the Mikimoto Pearl Research Laboratory. It also supports the annual Misaki Marine Biological Station Open Practical Course, part of the FHL E.S. Morse Japan/U.S. Exchange Program.
