Asuka Saito | Founder of three x seven Jewelry

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. We are not only pursuing our own profits but are also trying to be able to be part of the solution to the world's various environmental and social issues.
