A lab-grown diamond is a real diamond: it has the same composition and properties as a natural one. The difference is its origin, price and resale value.

## What they are

Both are crystallized carbon, with the same hardness (10 on the Mohs scale). A natural one formed underground over billions of years; a lab-grown one is created in weeks with HPHT or CVD processes.

## Can you tell them apart?

Not by eye or with a loupe. Only specialized instruments detect it, and many lab-grown diamonds carry a laser inscription.

## Price and value

At the same size and quality, a lab-grown diamond is significantly cheaper. A natural one holds its resale value better, although it is not a safe investment.

## Certificate

In both cases ask for a report from an independent lab (for example GIA or IGI) stating the type and the [4Cs](https://www.711grados.com/en/diamond-4cs-cut-color-clarity-carat/).

## How to choose

If you prioritize size and budget, lab-grown. If you value natural origin and rarity, natural. There are other options, such as [moissanite](https://www.711grados.com/en/moissanite/), which is a different gemstone.
