Dream Bigger: Get a 2x larger diamond at the same price

Lab-grown diamonds are chemically, optically and physically the same as mined diamonds right down to the atom. Our diamonds are 40 - 50% larger than a mined diamond for the same price.

Using lab-grown diamonds means you get can a larger stone, use more stones or both without compromising quality or budget.

Get bigger and higher quality — no matter your budget.

I ordered my custom wedding ring and the experience and result was fantastic. The whole process through emails but Vinny took a personalised approach and always replied promptly... and worked with me to get what I wanted within my budget. I recommend Four Words to start your journey with ethical custom jewellery.

Never worry about having a poor quality diamond

Forget the 4Cs with the Four Words quality standard.

We keep it simple for you, by picking the best-looking diamond possible for you.

The 4C's (Cut, Colour, Clarity, Carat) often complicate the process, either missing key features that make a beautiful, bright diamond or leading to overspending on features that don't matter.

Only the top 2% of diamonds meet our strict quality standards, meaning you will always get the best without paying extra.

Clean, Green, Luxury

Our lab grown diamonds are grown above ground in clean, high-tech facilities using a combination of heat and pressure to create ‘rough’ diamonds — the same process as in nature.

These ‘rough’ diamonds are exactly the same as the ones mined from the Earth — including the unique imperfections.

It’s a luxury you can feel good about.
