Creating jewellery that shines with purity

We strive to bring you the most beautiful pieces of jewellery created in an ethically responsible way with a particular focus on environmental sustainability.

RJC Certification

RJC Certification

In August 2023, Mikimoto obtained Code of Practice (COP) certification from the Responsible Jewellery Council (RJC). The RJC is an international non-profit organization in the jewellery and watch industry that was established in 2005. It has more than 1,500 member companies that span the entire supply chain, from mining suppliers to retail jewellers. In order to realize responsible trading in all processes, the RJC has established and promotes compliance with ethical, human rights, and environment-friendly standards.

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.
