Luxury with Purpose: The Materials We Choose
We believe jewellery should be more than beautiful, it should be responsible. At Astella, every material is carefully selected for both its quality and its conscience.
Our Single Mine Origin (SMO) gold, sourced from the Yanfolila mine in Mali, is fully traceable from mine to finished piece. Mined in accordance with the World Gold Council’s Responsible Gold Mining Principles, it offers complete transparency. with no premium on price and no compromise on ethics.
All of our diamonds are conflict-free, certified through the Kimberley Process, and we go further by working closely with suppliers to uphold human rights and environmental responsibility at every stage.
We also offer a growing collection of lab grown diamond jewellery, which delivers the brilliance of traditional diamonds with a lighter environmental footprint.
Sustainability at Every Step
As creators of heirloom-quality jewellery, we know the choices we make today shape the world we leave behind. Our commitment to sustainability goes beyond sourcing, from how materials are mined to their impact on communities and ecosystems.
We donate a percentage of every sale to Ecologi, supporting reforestation projects that help restore what the jewellery industry has historically damaged. It’s one way we give back. ensuring our legacy includes more trees than we take.
Where possible, we prioritise local production, low-emission suppliers, and thoughtful design. Each Astella piece is crafted to last. in both style and sustainability.
While many jewellers can’t trace their materials, we believe you deserve better. From SMO gold to lab grown diamonds, our supply chain is built to be ethical, transparent, and aligned with your values.
