Our founder, Tobi
"Not Mined was born out of a deeply personal journey. My name is Tobi, and like many people, I struggled to find a diamond ring that felt truly meaningful when I was searching for the perfect one for my wife. I didn't just want a ring—I wanted something with soul, something ethical, and something that could be uniquely ours.
But what I found was a jewelry industry that often lacked transparency, didn't offer customisation, and too often turned a blind eye to the environmental and human cost of mined diamonds. As someone with African heritage, I've seen the impact diamond mining has on our communities and landscapes. I knew there had to be a better way—one that didn't compromise on brilliance, beauty, or ethics.
So I started learning. About lab-grown diamonds, about craftsmanship, and about creating something that's not just beautiful, but meaningful.
At Not Mined, we offer conflict-free, lab-grown diamonds that shine just as bright—if not brighter—than anything mined from the earth. We make jewelry that's customisable, personal, and designed to celebrate your story, not someone else's.
We believe you should never have to choose between luxury and doing the right thing. Every piece we create empowers you to wear your values with pride—jewelry that reflects who you are, and what you stand for.
This isn't just about diamonds. It's about redefining what it means to give, to love, and to wear something that matters."
