Sourcing & Sustainability

Sourcing & Responsibility

At Mon Pilar, we believe that fine jewelry carries a responsibility to honor both the materials we work with and the people behind them. We thoughtfully source our materials through trusted suppliers and partners who share our commitment to quality, transparency, and responsible practices.

Recycled Gold

Our casting partners exclusively use recycled gold in their casting processes. Recycled gold maintains the same integrity and composition as newly mined gold while reducing the demand for newly extracted materials.

Natural Diamonds

We source natural diamonds from trusted suppliers who prioritize transparency and responsible sourcing. Where possible, we choose recycled natural diamonds, giving previously owned stones a renewed life while reducing the demand for newly mined materials. We also work with suppliers who offer responsibly sourced diamonds, including Canadian mined stones produced under some of the world’s strictest labor and environmental standards.

Lab Grown Diamonds

We source lab grown diamonds from suppliers that prioritize responsible production practices. Our lab grown diamonds are either SCS Certified, carbon neutral, or grown using renewable energy.

All diamonds are independently certified by IGI or GIA for quality and authenticity.

Responsible Practices

Founder Brigid McNellis is a member of Ethical Metalsmiths, a leading community platform for responsible jewelry in the United States that supports education, connection, and action within the jewelry industry.

Vintage & Unique Finds

Through our Vintage & Unique Finds collection, Mon Pilar gives previously loved solid gold jewelry a new life. By offering these pieces with thoughtful, minimal markups, we make it possible to discover beautifully made fine jewelry at a more accessible price point while supporting a more circular jewelry economy.

The collection offers a way to explore different styles and discover pieces that feel personal and unique.

The collection also supports the longstanding network of jewelry dealers and specialists in New York who source, trade, and circulate previously owned jewelry, helping extend the life of each piece.

Made in New York City

Every Mon Pilar piece is designed in New York City and brought to life through Brigid’s studio and a trusted network of local specialists. Rather than outsourcing production overseas, we work closely with skilled craftspeople in New York, maintaining a direct connection to the process and supporting the expertise of our local jewelry community.
