Our Ethics & Guarantee

Dedicated To The Environment

We are dedicated to environmentally sound, low-impact manufacturing, which means we use very little large-scale manufacturing or chemical processes in our ethically sourced jewelry! Each heirloom quality design from engagement rings to earrings is entirely made in Boston Massachusetts, using no overseas manufacturing or components. We love and respect Mother Nature and are dedicated to preserving our natural resources. Read more about our Craftsmanship and Ethics.

Ethically Sourced Diamonds & Gems

All of our diamonds and gemstones are ethically sourced from reputable suppliers and are of conflict-free origin, or lab-grown. We use a very small group of diamond and gemstone suppliers to maintain quality and a reliable ethical supply we trust. Too many gem suppliers result in too many hands in the sourcing supply chain making it harder to maintain ethical sourcing. Read more about our Diamond and Gemstone sourcing, or about our Ethical Diamond Purchasing Advantages.

Ethical Sourcing

Heirloom Quality

Our fine jewelry is made by hand using engineering, science, and old-world jewelry techniques that create a quality, and design aesthetic not available in mass-produced jewelry. Our process involves skilled jewelry designers using advanced computer-aided design software to create the original design. The designs are then individually cast, hand prepared, and made ready for stone setting. Our ethical diamonds and gemstones are then set by hand, using age-old setting tools and skill. The piece is then expertly hand-finished all in Boston. Learn more about how Our Designs are created.

Ethically sourced Wedding Rings

100% Free From Threat Metals

All of our gold 14K solid gold and 950 platinum is from recycled and ethically mined pure metal that is both LBMA and LPPM, free from threat, OCED compliant. Recycled metal is as pure and strong as non-recycled material, but is better for the earth and is conflict free without any reduction in quality.
