We are proud to announce that Skydiamond has been officially awarded the GreenCode Global Sustainability Accreditation, joining a small group of forward-thinking businesses recognised for truly embedding sustainability into the heart of what they do.
This prestigious certification underscores our unwavering commitment to ethical innovation, environmental stewardship, and redefining what luxury can—and should—look like.
What Is GreenCode?
GreenCode is an independent organisation with over 25 years of sustainability expertise across multiple industries. Its rigorous accreditation framework is built to help future-facing organisations measure, improve, and prove their environmental and ethical performance.
Unlike many sustainability labels, GreenCode is both independently audited and based on clear operational standards—helping businesses transition from intention to verified impact. Becoming a GreenCode-accredited brand is not simply a milestone; it’s a signpost of measurable change.
Setting a New Standard for Jewellery
At Skydiamond, we’ve always believed in doing things differently—taking carbon from the sky and turning it into the world’s most ethical lab grown diamonds. While traditional diamond mining is one of the most extractive and damaging industries on Earth, our process is the opposite: carbon-negative, solar-powered, zero-extraction luxury.
Receiving GreenCode certification validates our deep commitment to:
- Sustainable materials: 100% lab-grown diamonds made from atmospheric carbon
- Clean energy: Powered entirely by renewable sources
- Circular systems: Reclaiming, repurposing, and reducing wherever possible
- Ethical culture: Fair working practices and transparent supply chains
- Continuous innovation: Ongoing improvements in product, packaging, and production
Following a detailed, independent audit, Skydiamond received an excellent score, reflecting the strength of our sustainability strategy, governance, and culture.
A Message from Our CEO
“We are delighted to be awarded the prestigious GreenCode ‘Global Sustainability Accreditation’. This is down to continuous improvements and conscious operations by the dedicated Sky team – actively practicing our ‘another way’ mission; to live our lives sustainably without giving up what we love or need.”
— Madeleine Macey, CEO, Skydiamond
What This Means for Our Customers

When you select one of our engagement rings, wedding bands or fine jewellery pieces, you’re not just investing in beauty and craftsmanship—you’re choosing a product that’s better for the planet, better for people, and better for the future.
We believe that luxury should never cost the Earth. With this accreditation, we’re one step closer to making that belief a new normal.

We’ll continue to push boundaries, ask questions, and evolve what it means to be a sustainable luxury brand. From developing more circular designs to building community-led environmental initiatives, our commitment is ongoing.
We’re grateful to our customers, collaborators, and team who believe in our mission and have helped us get to this point. Let this be proof that there is another way.
