What Are Lab Grown Diamonds?
Lab grown diamonds (also called lab-created, synthetic, or cultured diamonds) are real diamonds created in controlled laboratory environments using advanced technology. They possess identical chemical composition (pure carbon), crystal structure, and optical properties to natural diamonds.
How They’re Made
Two primary methods create lab grown diamonds:
- HPHT (High Pressure High Temperature): Mimics natural diamond formation conditions deep within the Earth
- CVD (Chemical Vapor Deposition): Uses carbon-rich gas to grow diamonds layer by layer
Important: Lab grown diamonds are NOT cubic zirconia or moissanite. They are genuine diamonds with the same hardness (10 on Mohs scale), brilliance, and fire as mined diamonds.
Quality & Appearance: Can You Tell the Difference?
Visual Comparison
The short answer: No. Even professional gemologists cannot distinguish lab grown from natural diamonds with the naked eye. Both are graded using the same 4Cs:
- Cut: Determines brilliance and sparkle
- Color: Ranges from D (colorless) to Z (light yellow)
- Clarity: Measures internal inclusions
- Carat: Weight and size
Certification Standards
Reputable lab grown diamonds come with certifications from:
- IGI (International Gemological Institute)
- GIA (Gemological Institute of America)
- GCAL (Gem Certification & Assurance Lab)
Lab Grown vs Natural Diamond Comparison
| Feature | Lab Grown | Natural |
|---|---|---|
| Chemical Composition | Pure Carbon (C) | Pure Carbon (C) |
| Hardness | 10 (Mohs Scale) | 10 (Mohs Scale) |
| Brilliance & Fire | Identical | Identical |
| Visual Appearance | Indistinguishable | Indistinguishable |
| Price (1 carat) | $800-$1,500 | $2,000-$4,000 |
| Environmental Impact | Lower | Higher |
Price & Value Analysis: The Cost Advantage
Significant Savings

Pros & Cons of Lab Grown Diamond Earrings
✓ Advantages
- Significant Cost Savings: 40-60% less expensive than natural diamonds
- Identical Quality: Same physical, chemical, and optical properties
- Ethical & Conflict-Free: No mining-related human rights concerns
- Environmentally Friendly: Lower carbon footprint and no land disruption
- Larger Sizes Accessible: Afford bigger, better quality diamonds
- Certified & Guaranteed: Come with proper grading certificates
- Perfect for Daily Wear: Less financial stress if lost or damaged
- Modern & Innovative: Appeals to tech-savvy, conscious consumers
✗ Disadvantages
- Lower Resale Value: Typically 20-30% of purchase price
- Decreasing Prices: Technology improvements may reduce future value
- Less Romantic Appeal: Some prefer natural diamond symbolism
- Limited Vintage Options: No antique or estate pieces available
- Market Perception: Still viewed as “less prestigious” by some
- Investment Concerns: Not ideal for wealth preservation
Durability & Longevity: Will They Last?
Yes, absolutely. Lab grown diamonds are just as durable as natural diamonds because they are chemically identical.
Key Durability Facts
- Hardness: 10 on Mohs scale (hardest natural material)
- Scratch Resistance: Excellent – only another diamond can scratch it
- Heat Resistance: Stable up to 1,400°F (760°C)
- Chemical Resistance: Unaffected by household chemicals
- Lifetime Wear: Will not cloud, fade, or deteriorate over time
Care & Maintenance Tips
- Clean regularly with mild soap and warm water
- Store separately to prevent scratching other jewelry
- Remove during heavy physical activities
- Professional cleaning and inspection annually
- Check settings and prongs every 6 months
Resale Value Considerations
This is where lab grown diamonds differ most significantly from natural diamonds.
The Reality
- Lab grown diamonds: Resell for 20-30% of purchase price
- Natural diamonds: Resell for 25-50% of purchase price
Why Lower Resale Value?
- Abundant Supply: Can be produced on demand
- Decreasing Production Costs: Technology improvements lower prices
- Market Perception: Viewed as “manufactured” rather than “rare”
- Newer Market: Less established secondary market
Important Perspective
If you’re buying earrings to wear and enjoy (not as an investment), the lower resale value is offset by the 40-60% initial savings. You’re still ahead financially compared to buying natural diamonds.
Example: Spend $1,500 on lab grown earrings (resell for $450) vs. $4,000 on natural earrings (resell for $1,600). You save $2,500 upfront, which exceeds the $1,150 resale difference.
Buying Guide: How to Choose Lab Grown Diamond Earrings
1. Prioritize Cut Quality
Cut affects sparkle more than any other factor. Look for:
- Excellent or Ideal cut grades

3. Select Clarity Wisely
For earrings, you can go lower in clarity since they’re viewed from a distance:
- VS2-SI1: Best value – inclusions invisible to naked eye
- VVS1-VVS2: If you want perfection
- Avoid I1-I3 clarity grades
4. Verify Certification
Always buy certified diamonds from reputable labs:
- IGI (most common for lab grown)
- GIA (gold standard)
- GCAL
5. Choose Quality Settings
- 14K or 18K gold: Durable and valuable
