Diamonds have long symbolized luxury, love, and eternal commitment. However, as technology advances, lab grown diamonds have entered the market as a compelling alternative to real (natural) diamonds. Whether you’re shopping for an engagement ring, investment, or fashion piece, understanding the difference between lab grown diamond vs real diamond can help you make an informed decision.
What Are Real Diamonds?
Real diamonds, also known as natural diamonds, are formed deep within the Earth’s mantle under extreme heat and pressure over billions of years. They are mined from the Earth through mining operations around the world.
Key characteristics of real diamonds:
-
Formation: Naturally occurring, created over millions to billions of years.
-
Source: Extracted through mining.
-
Value: Traditionally considered valuable and rare.
-
Inclusions: May contain natural imperfections or inclusions due to the geological process.
-
Certification: Usually certified by organizations like GIA, AGS, or IGI.
What Are Lab Grown Diamonds?
Lab grown diamonds, also called synthetic or man-made diamonds, are diamonds created in a laboratory using advanced technological processes that mimic natural diamond formation. These diamonds have the same chemical, physical, and optical properties as natural diamonds.
Methods of creation:
-
CVD (Chemical Vapor Deposition): Carbon gases are deposited layer by layer to form a diamond crystal.
-
HPHT (High Pressure High Temperature): A small lab made diamonds seed is subjected to high pressure and temperature to grow a diamond.
Lab Grown Diamond vs Real Diamond: Similarities
-
Chemical Composition: Both are pure carbon crystals.
-
Physical Properties: Hardness, brilliance, refractive index, and sparkle are identical.
-
Appearance: Lab grown diamonds look visually indistinguishable from real diamonds to the naked eye.
-
Durability: Both are extremely durable and suitable for everyday jewelry.
-
Certification: Lab grown diamonds are also graded and certified similarly to natural diamonds.
Lab Grown Diamond vs Real Diamond: Differences
| Aspect | Real Diamond | Lab Grown Diamond |
|---|---|---|
| Origin | Naturally formed underground | Created in a lab using technology |
| Environmental Impact | Mining can be environmentally taxing | Generally more eco-friendly |
| Cost | Typically more expensive due to rarity | Usually 20-40% less expensive |
| Rarity | Rare and limited supply | Infinite supply, reproducible |
| Inclusions | Natural imperfections common | Fewer inclusions, often purer |
| Resale Value | Historically higher resale value | Resale market still developing |
| Ethical Concerns | Potential for “blood diamonds” | Guaranteed conflict-free |
Pros and Cons of Real Diamonds
Pros:
-
Traditional symbol of rarity and status.
-
Holds resale and investment value.
-
Unique natural origin, with individual inclusions.
Cons:
-
Higher price due to mining and rarity.
-
Environmental and ethical concerns related to mining.
-
Limited supply.
Pros and Cons of Lab Grown Diamonds
Pros:
-
More affordable for the same size and quality.
-
Eco-friendly with less environmental damage.
-
Guaranteed ethically sourced.
-
Same physical and optical properties as natural diamonds.
Cons:
-
Resale value is generally lower.
-
Perceived as less “authentic” by some buyers.
-
Market is still relatively new and evolving.
How to Choose Between Lab Grown Diamond vs Real Diamond?
Consider Your Priorities:
-
Budget: Lab grown diamonds offer better value for the price.
-
Ethics: Lab diamonds are a clear choice if you want conflict-free and environmentally friendly stones.
-
Resale: If resale or investment is your goal, real diamonds may hold better value.
-
Sentimental/Tradition: Some prefer natural diamonds for their historical and emotional significance.
Conclusion
The debate between lab grown diamond vs real diamond ultimately comes down to personal preference and priorities. Both types are stunning, durable, and certified gems. Lab grown diamonds provide a modern, sustainable, and affordable option without compromising beauty, while real diamonds carry the mystique of nature’s ancient craftsmanship and lasting value.
