Why Lab Made Diamonds?
At Ahimsa London, we believe diamonds should be a symbol of love, not exploitation. Traditional diamond mining has been linked to conflict diamonds, environmental destruction, and unethical labour practices.
That’s why we founded Ahimsa London in 2017 — to create a better way. Our lab-grown diamonds are 100% conflict-free, cruelty-free, and sustainable, offering the same brilliance and durability as mined diamonds, without the harm.
With our jewellery , you can celebrate life’s most precious moments with diamonds that are not only beautiful, but also ethical and sustainable. Choosing lab-made diamonds means choosing luxury with a conscience.

The difference is only how it was created, not what it is

Real Diamonds, Just a Different Journey
Lab-made diamonds are real diamonds. They share the exact same chemical composition, atomic structure, and physical properties as mined diamonds.
The only difference is how they are created: one forms deep within the earth over millions of years, the other is grown in a high-tech laboratory in just weeks — with no mining, no conflict, and no environmental devastation.
Unlike cubic zirconia or moissanite, which only mimic the look of diamonds, lab-grown diamonds are genuine diamonds — certified, graded, and cut in the same way as their mined counterparts.
