Buying an engagement ring is one of the most significant and exciting purchases you'll make. However, it can also feel daunting and overwhelming, especially when you're navigating a new industry filled with unfamiliar terms. At The Cornish Diamond Co., we believe that this important moment should be met with clarity, not confusion. We started this company to be your guide. Supportive, transparent, and genuinely honest.
Our journey began in Cornwall, where our roots are deeply set in the rugged coast and creative spirit of the county. We're proud to be Cornish, and we’re passionate about bringing a new kind of business here. One that contributes to our community and carves a future for innovation. Driven by our passionate team, this ethos of authenticity and integrity is at the heart of everything we do.
We believe that true luxury should never come at a cost to the planet or its people. As a part of our commitment to sustainability, our jewellery is crafted using recycled gold and platinum, ensuring our metals are sourced responsibly and sustainably. We exclusively use lab grown diamonds as a modern choice that delivers exceptional beauty without the exploitations of traditional mining.
As a proud member of the Responsible Jewellery Council, our entire supply chain is held to the highest ethical and sustainable standards. This guarantees that human rights are upheld, working environments are safe, and every step of our process is fully transparent.
We believe in using our profits to contribute to a better world. That's why we've partnered with GreenSpark, allowing us to make a direct impact with every single sale. By choosing us, you'll help fund vetted climate-positive projects worldwide, from planting trees to providing clean water.
Choose with confidence. Our transparent guides are designed to demystify the world of fine jewellery, putting you in control. From understanding the 4Cs and identifying different diamond cuts to finding your perfect ring size, our resources are here to support you on your journey.
Our Logo
The Dara Knot
The story of our Cornish roots is woven into our logo. The ancient Celtic emblem of the Dara Knot is inspired by the enduring oak tree, representing strength, resilience, and unity, reflecting connections that truly last forever.
In honour of our heritage, we entwined the knot with four diamonds. Together, they represent beauty and life’s most treasured moments, weaving that sparkle directly into the strength of tradition.
