What Are Lab Grown Diamonds?
Lab grown diamonds, also called lab created diamonds or man made diamonds, are real diamonds produced in advanced laboratories using cutting-edge technology that replicates the natural diamond formation process.
They have the same:
- Chemical composition (pure carbon)
- Crystal structure
- Hardness (10 on Mohs scale)
- Optical brilliance

How Lab Diamonds Are Created
Two main methods are used:
- HPHT (High Pressure High Temperature)
- CVD (Chemical Vapor Deposition)
Both replicate natural conditions but inside controlled lab environments, allowing production within weeks rather than billions of years.

What Are Natural Diamonds?
Natural diamonds are formed deep within the Earth's mantle under intense heat and pressure over 1–3 billion years. They are brought to the surface through volcanic eruptions.
Their rarity and geological history give them a sense of timeless exclusivity.
Why Natural Diamonds Are Considered Rare
- Limited geological supply
- Complex mining process
- Finite natural reserves
- Historical value

How Lab vs Natural Diamonds Are Formed
| Factor | Lab Grown Diamond | Natural Diamond |
|---|---|---|
| Origin | Laboratory | Earth's Mantle |
| Time to Form | Weeks | 1–3 Billion Years |
| Environmental Impact | Lower | Mining Required |
| Rarity | Controlled Production | Finite & Natural |
Can You Tell the Difference Visually?
No. Even professional gemologists require specialized equipment to distinguish lab grown from natural diamonds.
To the naked eye, both appear identical in:
- Brilliance
- Fire
- Sparkle
- Clarity
Price Comparison: Lab Grown vs Natural Diamonds
One of the most significant differences is price.
Average Price Difference
Lab grown diamonds typically cost 30% to 60% less than natural diamonds of similar quality.
| 1 Carat Round | Lab Grown | Natural |
|---|---|---|
| Excellent Cut, VS1, G Color | Lower Price Range | Higher Price Range |
This price difference allows buyers to choose larger carat sizes within the same budget.
4Cs Comparison: Cut, Color, Clarity, Carat
Cut
Identical grading standards apply to both types.
Color
Both range from D (colorless) to Z (light yellow).
Clarity
Lab diamonds often have fewer inclusions due to controlled growth.
Carat
Lab diamonds allow larger carat sizes for lower cost.
Durability & Hardness
Both types rank 10 on the Mohs hardness scale. This makes them equally suitable for daily wear engagement rings.
Environmental Impact
Lab Grown Diamonds
- No large-scale mining
- Reduced land disruption
- Lower carbon footprint (depending on energy source)
Natural Diamonds
- Mining required
- Land excavation
- Water usage impact
Resale & Investment Value
Natural diamonds traditionally hold stronger resale perception due to rarity.
Lab grown diamonds are ideal for personal enjoyment and value-focused buyers rather than investment speculation.
Which Diamond Should You Choose?
Choose Lab Grown If:
- You want maximum size for your budget
- Sustainability matters to you
- You prioritize value
Choose Natural If:
- You value geological rarity
- Tradition matters deeply
- You see it as heritage jewelry
