Lab-Grown Diamonds vs Natural Diamonds: The Complete Guide
What Are Lab-Grown Diamonds?
Lab-grown diamonds are real diamonds — chemically, optically, and physically identical to diamonds formed in the earth over billions of years. The only difference is where they are created: in a controlled laboratory environment using HPHT or CVD technology.
A lab-grown diamond has the same crystal structure, the same hardness (10 on the Mohs scale), and the same brilliance as a mined diamond. Gemologists cannot distinguish one from the other without specialised equipment.
Lab-Grown vs Natural Diamonds: Key Differences
| Factor | Lab-Grown Diamond | Natural Diamond |
|---|---|---|
| Composition | 100% carbon crystal | 100% carbon crystal |
| Hardness | 10 / 10 (Mohs) | 10 / 10 (Mohs) |
| Formation time | 6–10 weeks | 1–3 billion years |
| Environmental impact | Significantly lower | Higher land and water use |
| Price | 40–70% less than natural | Benchmark pricing |
| IGI certification | Yes — same grading standards | Yes |
Are Lab-Grown Diamonds Real?
Yes. In 2018, the US Federal Trade Commission updated its definition of "diamond" to remove the word "natural," explicitly recognising lab-grown diamonds as genuine diamonds. Every Nivara diamond is IGI-certified and graded by the same criteria: Cut, Colour, Clarity, and Carat.
Environmental and Ethical Considerations
- No land excavation or habitat disruption
- No child labour or conflict-zone sourcing concerns
- Significantly smaller carbon footprint per carat
- Complete traceability from creation to setting
The Price Difference
Lab-grown diamonds are typically 40–70% less expensive than comparable natural diamonds. At Nivara, this means access to IGI-certified stones that deliver the visual impact of much larger natural diamonds — at a fraction of the cost.
How Are Lab-Grown Diamonds Graded?
Every Nivara diamond is certified by IGI (International Gemological Institute) — the world's leading grading authority for lab-grown diamonds — using the same four C's: Cut, Colour, Clarity, and Carat.
