Lab-grown vs natural diamond: what you need to know

Lab-grown diamonds have become a serious choice for engagement rings in recent years. We often hear the question: "Are they even real?" The answer is yes — they are real diamonds. Let's look at what that means.

Are lab-grown diamonds real?

Yes. A lab-grown diamond is chemically, physically and optically identical to a natural one — the same carbon crystal structure, the same hardness (10 on Mohs), the same brilliance. The only difference is origin: the natural one formed over billions of years in the earth, the lab-grown one forms in a few weeks in a controlled environment.

How they're told apart

With the naked eye or an ordinary loupe they cannot be distinguished. Only specialized labs differentiate them, using equipment that detects tiny differences in crystal growth. That's why with lab-grown diamonds a certificate is especially important — the stone should be clearly labeled as lab-grown.

Price

This is the main appeal: a lab-grown diamond costs significantly less than a comparable natural one — often 50–70% less for the same size and quality. This means that for the same budget you get a larger or higher-quality stone.

Value over time

An important difference for an informed decision:

  • Natural diamonds hold value better and, due to rarity, have potential for long-term value.
  • Lab-grown diamonds lose value faster as production costs fall; view them as beautiful jewelry, not an investment.

Ethics and environment

Both approaches have their arguments:

  • Lab-grown: no mining, traceable origin, smaller environmental footprint (depending on the energy source)
  • Natural: modern traceable programs (e.g. certified origins) ensure ethics; mining in some places supports local communities

Our advice: there's no wrong choice — only your choice. What matters is that you know what you're buying and that the stone is certified and honestly labeled.
