This includes ・Using 100% recycled metals in our manufacturing processes. ・Using fair-trade materials to improve the lives of workers and their working environment. ・ Using no-conflict diamonds and gemstones. ・Using recyclable, biodegradable, and ECO-certified packaging ・Supporting activities for organizations engaged in environmental activities and solving social problems. By supporting ethical suppliers and every facet of fair trade jewelry, we believe we can make a difference in our communities.

Craftsmanship

The outstanding creativity of our jewelry designs reveals the precise artistry of our craftspeople.

All three x seven Jewelry is guaranteed to be made of the highest quality materials and jewelry fabrication, and is designed to last a lifetime. We offer a range of products: bridal jewelry, wedding bands, and fine jewelry.

Processing Time

The time we need to prepare an order for shipping varies because our items are made to order. three x seven Jewelry does not carry excess inventory for sustainability reasons. Therefore, we recommend that you place your order earlier if you consider to purchase a gift. Please allow 5 to 21 days production time for your order to ship out. Please contact us with the item number for more detail. If you would like to order bridal jewelry, there will be a button "ADD TO QUOTE" instead of "ADD TO CART". When you add to quote, there will be a quote cart icon on the right up. From the quote cart, you can request an inquiry by clicking "SUBMIT INQUIRY". OR you can simply email us with item numbers. We will soon contact you about purchasing your select items. You will receive another notification when your order has shipped.

Help Jewelers for Children

Jewelers for Children was founded in 1999 by the U.S. jewelry industry with the mission of helping children in need. Since its inception, JFC has donated more than $57 million to programs benefiting children whose lives have been affected by illness, abuse, or neglect through their charity partners. We donate some percentage of the sales price to the JFC.

Asuka Saito | Founder of three x seven Jewelry

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