Diamonds have long been associated with beauty, luxury, and lasting value. Today, buyers have more choices than ever before, with both natural diamonds and lab grown diamonds available in a wide range of shapes, sizes, and qualities.
One of the most common questions shoppers ask is: What is the difference between a lab grown diamond and a natural diamond?
While both diamonds look identical to the naked eye and share the same physical and chemical properties, there are important differences in their origin, price, sustainability, and value proposition. This guide explores everything you need to know when comparing lab grown diamonds and natural diamonds.
What Is a Natural Diamond?
Natural diamonds are formed deep within the Earth's mantle under extreme heat and pressure over billions of years. Through volcanic activity, these diamonds are brought closer to the Earth's surface, where they are eventually mined and cut into gemstones.
Each natural diamond is unique and has undergone a remarkable geological journey before reaching the market.
Key Characteristics of Natural Diamonds
-
Formed naturally over billions of years
-
Mined from the Earth
-
Composed of pure crystallized carbon
-
Available in a wide range of qualities and sizes
-
Traditionally considered rare and valuable
What Is a Lab Grown Diamond?
Lab grown diamonds are real diamonds created in advanced laboratories using technology that replicates the natural diamond-growing process. The most common production method is Chemical Vapor Deposition (CVD), which allows a diamond crystal to grow layer by layer under controlled conditions.
Despite being created in a laboratory, a lab grown diamond is chemically, physically, and optically identical to a natural diamond.
Key Characteristics of Lab Grown Diamonds
-
Created using advanced technology
-
Made from crystallized carbon
-
Identical to natural diamonds in composition
-
Available in certified quality grades
-
More affordable than natural diamonds
Are Lab Grown Diamonds Real Diamonds?
Yes.
Lab grown diamonds are real diamonds. They are not diamond simulants such as cubic zirconia or moissanite.
Both natural and lab grown diamonds share:
-
The same chemical composition
-
The same crystal structure
-
The same hardness rating of 10 on the Mohs scale
-
The same brilliance and fire
-
The same durability for everyday wear
Even professional gemologists require specialized equipment to determine whether a diamond is natural or lab grown.
Lab Grown Diamond vs Natural Diamond: Side-by-Side Comparison
| Feature | Lab Grown Diamond | Natural Diamond |
|---|---|---|
| Origin | Created in a laboratory | Formed naturally underground |
| Chemical Composition | Pure carbon | Pure carbon |
| Hardness | 10 Mohs | 10 Mohs |
| Sparkle | Identical | Identical |
| Durability | Excellent | Excellent |
| Certification | IGI, SGL and others | IGI, GIA and others |
| Availability | Readily available | Limited by mining supply |
| Price | More affordable | Higher cost |
| Environmental Impact | Generally lower | Mining required |
| Appearance | Identical | Identical |
Which Diamond Sparkles More?
Neither.
A diamond's sparkle depends on factors such as cut quality, proportions, polish, and symmetry rather than whether it is natural or lab grown.
A well-cut lab grown diamond will sparkle just as brilliantly as a well-cut natural diamond of the same quality.
When comparing diamonds, focus on:
-
Cut grade
-
Proportions
-
Symmetry
-
Polish
-
Clarity
-
Color
These characteristics influence brilliance far more than the diamond's origin.
Lab Grown Diamonds vs Natural Diamonds: Price Comparison
One of the biggest differences between the two options is price.
Lab grown diamonds typically cost significantly less than natural diamonds of comparable quality.
For example, a 1 carat diamond with the same color, clarity, and cut grade may cost substantially less when lab grown, allowing buyers to choose:
-
A larger carat size
-
Better clarity grades
-
Higher color grades
-
More elaborate jewellery designs
For many modern buyers, lab grown diamonds provide exceptional value without compromising on beauty or quality.
Sustainability Considerations
Many shoppers today consider environmental and ethical factors when purchasing diamond jewellery.
Lab grown diamonds are created in controlled environments without traditional mining operations. As a result, many buyers view them as a more sustainable alternative.
Natural diamonds, while responsibly sourced by many producers, require extraction from the Earth through mining processes.
Consumers who prioritize sustainability often choose lab grown diamonds because they offer the same visual beauty and durability with a different production process.
Durability and Everyday Wear
Both natural and lab grown diamonds rank 10 on the Mohs Hardness Scale, making them the hardest known gemstone material.
This means both are suitable for:
-
Engagement rings
-
Wedding bands
-
Earrings
-
Pendants
-
Bracelets
-
Daily wear jewellery
A lab grown diamond will not fade, cloud, or lose its sparkle over time.
Certification and Quality Grading
Both natural and lab grown diamonds can be independently graded and certified.
Certification reports evaluate:
-
Carat Weight
-
Color
-
Clarity
-
Cut Quality
-
Polish
-
Symmetry
-
Fluorescence
When purchasing a diamond, always choose a certified stone from a reputable seller to ensure transparency and quality assurance.
Who Should Choose a Lab Grown Diamond?
Lab grown diamonds are ideal for buyers who want:
-
Maximum value for their budget
-
Larger carat sizes
-
Higher quality grades
-
Sustainable alternatives
-
Modern diamond technology
-
Beautiful everyday jewellery
They are particularly popular for engagement rings, wedding bands, and custom jewellery.
Who Should Choose a Natural Diamond?
Natural diamonds may appeal to buyers who value:
-
Geological rarity
-
Traditional diamond heritage
-
Natural origin
-
Historical significance
For some consumers, the story of a diamond formed over billions of years remains an important part of the purchase experience.
Final Thoughts
Lab grown diamonds and natural diamonds are both genuine diamonds with identical beauty, brilliance, and durability. The primary difference lies in how they are created.
Natural diamonds are formed within the Earth over billions of years, while lab grown diamonds are produced using advanced technology that replicates the same natural conditions.
For many modern buyers, lab grown diamonds offer a compelling combination of exceptional quality, larger carat sizes, and outstanding value. Others may prefer the rarity and heritage associated with natural diamonds.
Ultimately, the best choice depends on your personal preferences, priorities, and budget. By understanding the differences between the two, you can confidently choose the diamond that best reflects your style and values.
Frequently Asked Questions
Can you tell the difference between a lab grown and natural diamond?
