A DIAMOND’S STORY SHOULD BE AS FLAWLESS

AS THE STONE ITSELF.

At Firma Tera, we believe a diamond’s value is not only measured by its clarity and cut, but by the integrity of its journey. Long before it reaches the polishing wheel or the showcase light, we ensure its path is free from conflict, exploitation, or hidden compromise.

More Than a Certification. Industry rules like the Kimberley Process are essential but for us, they are just the starting point.

A Higher Standard, Not Just a Requirement

The diamond industry has global rules like the Kimberley Process — but we treat them as a starting point, not a finish line. Our sourcing network is built on personal relationships with trusted miners and suppliers who share our belief in fairness, traceability, and respect for both people and planet.

Integrity You Can See

Every stone we handle carries a documented origin. We trace its movement, verify its authenticity, and work only with partners who uphold ethical labor, environmental stewardship, and full transparency. If a source cannot meet these standards, it simply doesn’t make it into our portfolio.

Shaping the Future of Diamonds

Ethical sourcing isn’t just about avoiding the wrong — it’s about actively creating the right. We support mining communities, encourage better practices, and participate in initiatives that push the industry toward greater accountability. Our vision is clear: a diamond market where beauty and responsibility are inseparable.

When you select a diamond from Firma Tera, you are choosing more than brilliance. You are choosing a supply chain built on trust, fairness, and respect at every step.

The Path Matters as Much as the Stone

Before a diamond is cut, graded, or polished, it has a journey. We make sure that journey is free from conflict, unfair labor, or hidden compromise. Our sourcing standards go beyond compliance because responsibility should never be optional.

  • Direct Relationships: We work only with trusted suppliers who value transparency.

  • Verified Origins: Every diamond comes with documented provenance.

  • Ethical Practices: Safe working conditions, fair labor, and community respect are non-negotiable.
