Our Commitments
Responsible Luxury
Astrea London was founded on a simple conviction: the finest diamonds need not be mined.
Responsibility here is not a campaign; it is a set of decisions about origin, materials, craft and proof — each of them verifiable.
Origin
Grown, not mined
Every Astrea stone is grown, not mined, so it involves no mining extraction. Each centre stone is independently certified.
Materials
Metals, packaging, workshop
- Responsibly sourced precious metals
- Our 18K gold and platinum come from refiners working with recycled material and audited supply chains.
- Considered packaging
- Presentation cases and shipping materials are FSC-certified, plastic-free and made to be kept.
- Made to order
- We produce to order rather than to stock, which reduces waste and unsold stock.
- Built to be repaired
- Cleaning, polishing, rhodium renewal and stone tightening are offered for life: the least wasteful piece is the one worn for decades.
Transparency
Documents you can check
Each centre stone carries an IGI / GIA report you can verify with the laboratory yourself, confirming its quality. Our precious metals are hallmarked to UK standards, and Astrea London is a registered Assay Assured Jewellery Retailer.
Philanthropy
Giving Back
A commitment that began long before Maison Astrea.
Giving back is one of the core values of Maison Astrea — a deeply held commitment that began long before the Maison itself.
For more than fifteen years, our founder, Nathalie Morrison, together with her family and children, has supported Sumbandila, returning year after year.
Based in rural Limpopo, South Africa, Sumbandila provides education, mentorship and opportunity to exceptional young people from deeply underprivileged backgrounds. Over the years, Sumbandila has helped support more than 300 children.
At the heart of this commitment is a simple belief: education is power.
As Maison Astrea grows, so too should its capacity to create opportunity. A percentage of Astrea's profits is dedicated to supporting education and helping young people build futures that circumstance might otherwise have placed beyond their reach.
From our Founder
Sumbandila has been part of my life and my family's life for more than fifteen years. My children and I return year after year, and I have had the privilege of seeing first-hand what becomes possible when a young person is given an opportunity.
I believe deeply that education is power. It gives a young person choices, independence and the possibility to shape their own future. And its impact reaches far beyond one life — into families, communities and generations to come.
When I founded Maison Astrea, I knew that this belief would be at its heart. As the Maison grows, I want our ability to create opportunity for others to grow with it. For me, that is one of the most meaningful expressions of luxury.
