Lab-grown Diamonds: Are synthetic diamonds real diamonds?

Lab-grown Diamonds: Real or Not? The Honest Answer

Lab-grown diamonds – that is, diamonds produced in a laboratory – are expected to reach a market share of over 40% in engagement rings by 2026. But are they “real” diamonds? And how do they differ from natural ones?

What are Lab-grown Diamonds chemically?

Laboratory diamonds are chemically, physically, and optically identical to natural diamonds. Both consist of pure carbon in the diamond crystal structure. Even with professional instruments, they can only be distinguished by specialized equipment (fluorescence spectroscopy).

How are they made?

• CVD (Chemical Vapor Deposition): Carbon gas is deposited on a crystal – the diamond grows layer by layer.
• HPHT (High Pressure High Temperature): Mimicking natural formation conditions – pressure and heat form a diamond from a seed crystal.

Price Comparison

• Natural Diamond (1 carat, G/VS1): approx. €5,000–8,000
• Lab-grown Diamond (1 carat, G/VS1): approx. €800–1,500

Lab-grown diamonds cost 70–85% less – for the same optical and physical result.

When to choose natural diamond, when lab-grown?

• Natural Diamond: For tradition, investment considerations, heirlooms, status symbols
• Lab-grown: For a larger stone on the same budget, ethical convictions, sustainability

Certification is mandatory

Both natural and lab-grown diamonds should be sold with a GIA, IGI, or HRD certificate. The certificate clearly states: “Natural” or “Laboratory-Grown.”
