The National Association of Jewellers

The National Association of Jewellers

We are delighted to announce that we members of the National Association of Jewellers.

Every National Association of Jewellers member is required to abide by the NAJ's Code of Conduct based on honesty, integrity and professionalism. The grant of arms gives customers peace of mind that they are dealing with a jewellery business they can trust. 

Upholding the NAJ Code of Conduct

As NAJ members, we are bound by a comprehensive Code of Conduct. It mandates not only legal compliance and fair dealing but also a shared commitment to transparency, client care, and responsible business practice.

For Skydiamond, these principles are not new. They are woven into the very foundation of how we operate. But this accreditation offers a formal recognition of the rigorous standards we set for ourselves—standards that distinguish Skydiamond as a leader in both innovation and integrity.


A Symbol of Authenticity and Assurance

The National Association of Jewellers is one of only a handful of trade associations to hold a Royal Charter grant of arms. In a sector where authenticity matters, this level of recognition carries meaningful weight. For our clients, it reinforces that Skydiamond is not only pioneering in sustainability but also rooted in professional excellence and consumer confidence.


What This Means for Skydiamond—and For You

1. Confidence in Provenance

Every Skydiamond piece begins with carbon captured from the atmosphere and is crafted using fully renewable energy. NAJ membership reinforces the importance of traceability and verified origin—principles that are fundamental to how we make our diamonds.

2. A Culture of Transparency

In an industry often clouded by opacity, we offer clarity at every stage—from diamond growth and grading to setting and certification. The NAJ’s rigorous ethical framework aligns with our own: nothing hidden, nothing compromised.

3. Excellence as Standard

From the purity of our materials to the expertise of our master artisans, every Skydiamond creation is made to exacting specifications. Being part of the NAJ connects us to the best practices of a wider professional network, reinforcing our pursuit of technical precision and timeless design.


Beyond Accreditation: A Broader Commitment

While NAJ membership is an important marker, it sits within a broader ecosystem of responsibility and innovation:

  • Carbon-Negative Diamonds
    Our laboratory-grown diamonds are created through a process that removes more CO₂ from the atmosphere than it emits, verified by independent research from Imperial College London.

  • Recycled Precious Metals
    We use 100% recycled gold and platinum, further reducing environmental impact without compromising on purity or quality.

  • Certification & Clarity
    All diamonds of 0.5 carats and above are certified by the Birmingham Assay Office and are measured on the 4cs, Cut, Clarity, Colour and Carat ensuring clarity both in quality and origin.
