Lab grown diamonds are chemically and physically identical to natural diamonds but have been made in a lab. The revolutionary gem is opening new jewellery possibilities for technologically minded buyers, as their scientific parity to earth-mined stones is absolute. Lab grown diamonds, their history, comparisons, prices, styles and pro tips, is what this guide is about.
Lab Grown Diamond Meaning
A lab-grown diamond is a real diamond made in a laboratory instead of mined from the earth. It is created by replicating the extreme heat and pressure found deep underground.
There are primarily two methods used:
1. High Pressure High Temperature (HPHT)
- Carbon is melted (1,400–1,600°C)
- Pressed (5–6 GPa)
- Uses metal catalysts
2. Chemical Vapour Deposition (CVD)
- Carbon-containing gas deposited layer by layer
- Grown on a diamond seed
- Vacuum chamber at 800–900°C
Why Are They Indistinguishable?
- Same carbon atom arrangement
- Same tetrahedral lattice structure
- Refractive index: 2.42
- Dispersion: 0.044
Lab grown diamonds are real diamonds, unlike cubic zirconia and moissanite, which are diamond simulants. They can be graded like natural diamonds and produced from small to large stones. Controlled environments allow production of flawless stones, free of inclusions common in earth-mined diamonds.
Ethics and Certification
- Uses 1/50th the energy of mining
- Can use recyclable electricity sources
- Avoids environmental destruction
- Certifications like IGI’s Laboratory Grown Diamond Report ensure transparency
For buyers in India, UK or US, lab grown diamonds democratise luxury, allowing flawless 2-carat stones without heirloom budgets.
Natural vs. Lab Grown Diamonds
Both rank 10/10 on the Mohs hardness scale, resist chipping equally and share identical sparkle.
Key Differences
| Feature | Lab Grown Diamond | Natural Diamond |
| Chemical Composition | 100% carbon | 100% carbon |
| Formation Duration | 2–6 weeks | 1–3 billion years |
| Price per Carat (Avg) | $600–1,500 | $3,000–10,000+ |
| Resale Value | Developing secondary market | High rarity premium |
| Purity/Inclusions | Often cleaner | Variable |
| Market Growth | 20–56% share by 2026 | Stable |
| Certification | IGI / GIA | GIA common |
Opt for lab grown when size matters. A 3-carat lab grown diamond dazzles like a rare natural at 1/10th the cost.
Are Lab Grown Diamonds Real or Fake?
Absolutely real. Gemological standards classify them as diamonds if they are monocrystalline carbon.
Common Myths Debunked
- “They yellow over time” – False
- “Inferior quality” – False
Detection requires UV spectroscopy or inscription readers. Resale is growing through certified platforms. Authenticity ensures buyer confidence and a “no compromise on forever.”
