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. 

Principled 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. 



We buy gemstones from suppliers that adhere to strict protocols in regards to the sourcing of both lab-created and mined gemstones. 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

We procures the majority of its diamonds from suppliers which have the membership of our suppliers with the Diamond Manufacturers and Importers Association of America (DMIA). This means that we share their commitment to upholding the highest standards for ethics, integrity, and professionalism in the diamond industry. Most polished diamonds originate from Canada, South Africa, Botswana, and Namibia.  


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.




Recycled Metals

We use SCS certified 100% recycled metals — gold, silver, and platinum products. SCS Global Services is an international leader in third-party certification and standards development in environmental and sustainability claims according to global standards.

As part of our continued commitment to the environment, three x seven Jewelry design our packaging to reduce waste whenever possible. 


  • Jewelry Boxes

The paper contains residues from organic products, which replace 15% of the wood pulp. For these boxes, a by-product from corn production is used. The glue is water-based. Both the wood and the cardboard boxes are FSC®-certified.


  • Mailer Envelope
100% Biodegradable: The bubble wrap is made of PBAT and modified corn starch. The envelope is made of kraft. They are certified by BPI, OK compost and meet the standards of ASTM 6400 and EN13432. They generates less CO2 than traditional plastic.

  • Postal Box
Eco-friendly, organic, recycled, Fairtrade®, and FSC®-certified products and inks are environmentally-friendly, vegetable oil-based such as soy inks. 

  • Ribbon
Eco-friendly woven ribbon is made from recycled plastic, making it an environmentally conscious alternative to the classic polyester ribbons.

  • Tissue Paper
Eco-friendly, FSC®certified products / FSC Mix 70%


▶︎FSC®certified products / FSC Mix 70%

The FSC® mark guarantees that all materials come from an FSC® forest, where no more wood is cut down than the forest can reproduce. This means better protection of the animal- and plant life, and all foresters have proper training, safety equipment and a decent wage, and ensures that products come from responsibly managed forests that provide environmental, social, and economic benefits.

The mark of responsible forestry.


Fair Price

three x seven Jewelry strives to exceed the expectations of our customers by offering well-made and well-designed pieces at an affordable fair price.

Combining traditional fine jewelry making with modern technology and partnerships with a close network of suppliers, we are able to build a business operation that is nimble and flexible and streamline our production to keep our costs low and avoid unnecessary factory costs and extra wastage that typically comes with mass production.

Relying on word of mouth and grassroots marketing means we are not paying fancy advertisement costs.
