Commitment
Sustainable Luxury
Astrea London was founded on a simple conviction: the finest jewellery should not require anything to be taken from the earth.
Sustainability here is not a campaign; it is a set of decisions about origin, materials, craft and proof — each of them verifiable.
Origin
Diamonds without extraction
Every Astrea stone is grown, not mined. No riverbed is diverted, no landscape displaced, no community disrupted to bring it into being — and its journey from seed to setting is documented at every step.
Materials
Metals, packaging, workshop
- Recycled 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 removes waste and unsold inventory from the equation.
- 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
Verifiable, not asserted
Sustainability claims mean little without proof. Each centre stone carries an IGI report you can verify with the laboratory yourself, our precious metals are hallmarked to UK standards, and Astrea London is a registered Assay Assured Jewellery Retailer.
Philanthropy
Giving back
At our core is Astrea's commitment to education, sustainability and preserving the environment. Beyond offering a sustainable and ethical alternative to mined diamonds, it is our intention to invest a portion of our profits towards the ongoing development and application of lab-grown diamonds within the medical industry — including optics, cancer treatment, dental treatment and water purification.
Astrea also actively supports philanthropic efforts in education, specifically in Africa, giving a percentage of its profit each year to help talented, determined children from underprivileged backgrounds complete an educational journey — creating the leaders and entrepreneurs who can effect much-needed change in their society and economy. The founders of Astrea have supported the education-focused non-profit organisation Sumbandila for years and believe in its invaluable, positive impact on the lives of children in Africa.
Ultimately, Astrea believes that education is power. When you choose our lab-grown diamonds, you acquire not only a symbol of elegance, but also contribute to our mission of supporting the environment and giving back to the community.
