About Us

Philosophy

"...We provide jewelry that brings smiles to the faces of everyone involved."

three x seven Jewelry is a San Francisco-based sustainable jewelry brand sold globally online that uses materials with low environmental impact and systems that contribute to society.

At three x seven Jewelry, our mission is t o contribute to the realization of a shining future by providing jewelry that brings smiles to all those who are involved.

Our vision is to provide truly beautiful jewelry that feels good to wear.

1. We provide emotional value through jewelry that connects the originally invisible "feelings" and the "meaning" of jewelry, and continues to be close to the owner as a tangible object.

We not only make jewelry shine, but also connect our customers' feelings and the meaning of jewelry, and help make their life stories shine through jewelry.

2. We aim for harmonious development with society by addressing social issues with jewelry that considers not only beauty, but also "people, society, and the environment."

By paying attention to various materials and people involved in the production process, such as the "environment" necessary for making jewelry, the "people" making it, and the "working environment" of those who mine it, we can have a positive impact on the environment and society.
