About Us

Social Responsibilities

three x seven Jewelry maintains an ongoing environmental consciousness and fair trade awareness in our manufacturing processes and in the lives of all of our associates. We are committed to conducting all operations in the most socially responsible manner possible—from our recycled metals to our ethically sourced diamonds and gemstones. We believe it is our duty to improve the lives of our associates and ensure they are compensated fairly for their labor. By supporting ethical suppliers and every facet of fair trade jewelry, we believe we can make a difference in our communities. And just as we are committed to bettering the global jewelry industry, we are committed to making our own local community a better place. 


Ethical Sourcing

Recognizing the challenges associated with providing precious materials in a responsible manner, we work closely with our suppliers to ensure our jewelry is produced in the most ethical way possible.


Recycled Metals

At three x seven Jewelry, we are committed to ethical sourcing and environmental sustainability in all aspects of our operations. This includes using 100% recycled materials in our manufacturing processes.



SCS Global Services Certifications

SCS Global Services is an international leader in third-party certification and standards development in environmental and sustainability claims according to global standards. We buy recycled metals from companies that received SCS's certification for 100% recycled metals, verifying that when we buy their manufactured metals—gold, silver, platinum, and palladium products—they have 100% recycled content. Learn More


Gemstone Sourcing

We buy gemstones from companies that adhere to strict protocols in regards to the sourcing of both lab-created and mined gemstones. As a natural resource, gemstones can be found almost anywhere, but they are mined, cut, and exchanged too frequently to keep traceable documentation of their exact source. However, we engage in several practices to ensure the integrity of the gemstones we purchase and believe in creating an open dialogue about gemstone sourcing to be as transparent and trustworthy as possible.



Ethically Sourced Diamonds

three x seven Jewelry gets the majority of its diamonds from companies that procure directly from suppliers that manufacture rough diamonds. Sourcing cut and polished diamonds that originate from Canada, South Africa, Botswana, Russia, Australia, and Namibia.

The membership of our suppliers with the Diamond Manufacturers and Importers Association of America (DMIA) means that we share their commitment to upholding the highest standards for ethics, integrity, and professionalism in the diamond industry. Together, we are committed to boosting consumer confidence in diamonds.


No-Conflict Diamonds

We are committed to selling conflict-free, ethically sourced diamonds. We believe it is completely unacceptable to tolerate conflict diamonds and human suffering in any way.

All rough and polished mined diamonds sold by three x seven Jewelry comply with the Kimberly Process.

    Asuka Saito


    Born in Sapporo/Hokkaido, Japan. Moved to the U.S. in 2005.

    While attending San Francisco State University, she studied psychology, color science, and gemology. While gaining experience at a jewelry store in San Francisco, she learned the basics of jewelry metal smithing under Alan Revere and Nyya Lark, and obtained jewelry professional certifications from the Gemological Institute of America.

    As a jewelry artist, she began creating original designs and won numerous awards including the Grand Prize at international design contests held in the United States, Japan, and Italy. She has exhibited her original works at art events and museums around the world, including the United States, Europe, China, India, and Japan. Her work has been featured in various media, both domestic and international. She has been selected to be a member of the jury for the 5th consecutive year since 2017 at the annual international design contest (A' Design Award & Competition) held in Italy.

    After working in sales at a jewelry store in San Francisco, she became the general manager and was in charge of direction including purchasing, planning, sales promotion, and public relations. After that, she became completely independent taking giving birth as an opportunity and started her own business.

    She launched three x seven Jewelry, a sustainable jewelry brand that uses materials and mechanisms with less environmental impact to contribute to solving environmental and social issues, which she had envisioned for many years.
