From our home in Cornwall, surrounded by the wild beauty of the coast, we've come to believe that a beautiful love story deserves to be celebrated with integrity. For us, that means a deep commitment to protecting the world that our own stories unfold in. Our approach to fine jewellery is simple: do better, care more, and create pieces you can feel good about, for today, tomorrow, and generations to come.
As part of this commitment, we are proud members of the Responsible Jewellery Council (RJC). This membership holds us to the highest ethical standards across the jewellery supply chain. It is an independent verification of our dedication to responsible business practices, ensuring every part of our process adheres to strict social, environmental, and human rights standards. It’s an assurance of our promise to a more responsible industry.
We've dedicated ourselves to a better way of creating fine jewellery, ensuring that every piece we craft has a positive impact. This is where our story begins.
Every piece of recycled gold and platinum we use is refined from existing precious metals, giving these precious materials a second life. This not only honours the value of these materials, but also allows us to craft stunning, lasting jewellery without contributing to the environmental and social costs of new mining.
We exclusively use lab-grown diamonds that are physically, chemically, and optically identical to mined diamonds. This choice is rooted in ethics, allowing us to deliver an undeniable sparkle with a transparent origin and a far lighter environmental footprint. It’s a commitment to a more responsible and brilliant future for jewellery.
CRAFTED WITH HERITAGE AND HEART
We believe true beauty comes from a place of respect, for people and for heritage. Our journey begins with skilled artisans in India, whose craft has been passed down for generations. This partnership allows us to use 100% recycled gold and platinum, as our partners specialise in casting with these materials. The castings are then returned to our UK workshop where our expert jewellers hand-set and finish each piece.
Our commitment goes beyond beautiful jewellery. The well-being of our partners is paramount, and their workshops are audited by the Responsible Jewellery Council (RJC). This guarantees our entire process meets the highest ethical and sustainable standards. By upholding fair working conditions and celebrating their artistry, we help preserve this incredible legacy. Every piece is a testament to their skill and our ethical commitment, connecting you to a remarkable story.
In addition to our ethical sourcing, we're proud members of GreenSpark. Every purchase you make helps fund vetted climate-positive projects worldwide, aligned with the UN Framework Convention on Climate Change. Your support contributes directly to initiatives like the EarthLungs Bees Project, The Water Project, and Global Climate Action, making a tangible difference for our planet.
A CHOICE to CHERISH
We design our pieces to be cherished for a lifetime and beyond, embodying a commitment to lasting quality. By creating timeless jewellery, we encourage a circular mindset, where pieces are passed down and loved for generations.
The Cornish Diamond Co. is a celebration of enduring love and shared values. By choosing us, you're joining us in a pledge to a more sustainable and thoughtful future.
