100% Ethical Jewellery & Conflict Free

When shopping for a mined diamond, most people need to make a sacrifice on either their values or on something they have dreamed of wearing. But with lab grown diamonds from Four Words , you won’t have to worry.

Our diamonds are ethically sourced and conflict-free because they're made in a lab instead of mined from the Earth. No exploitative labour practices or destructive mining methods are needed - just science and technology.

So you can shop with a clear conscience thanks to our lab grown diamonds - they're just as beautiful and brilliant as mined diamonds, without the hefty price tag.
