When it comes to choosing the perfect gem, the debate around lab grown diamond vs real diamond is more relevant than ever. As awareness grows about sustainability, ethics, and affordability, many buyers are turning to lab diamonds as a compelling alternative to traditionally mined stones. But what really separates these two types of diamonds, and which one is the better choice for you? This guide will break it all down so you can make an informed decision.
What Is a Lab Grown Diamond?
A lab grown diamond is created in a highly controlled laboratory environment using advanced technological processes that replicate the conditions under which natural diamonds form beneath the Earth’s crust. These diamonds are made of the same material—pure carbon crystallized in an isometric cubic system—as natural diamonds.
There are two main methods used to create lab diamonds:
-
High Pressure High Temperature (HPHT)
-
Chemical Vapor Deposition (CVD)
Both techniques produce diamonds that are chemically, physically, and optically identical to those mined from the earth.
What Is a Real Diamond?
A real diamond, also known as a natural diamond, is formed over billions of years under extreme heat and pressure deep within the Earth’s mantle. They are then mined, cut, and polished for use in jewelry and other applications.
Natural diamonds often contain inclusions or imperfections, which are part of what makes each one unique. They have long been considered symbols of luxury and rarity, which contributes to their high price tag.
Lab Grown Diamond vs Real Diamond: Key Differences
While lab diamonds and natural diamonds look and feel the same, there are a few critical differences you should know:
| Feature | Lab Grown Diamond | Real (Natural) Diamond |
|---|---|---|
| Origin | Created in a lab | Formed in the Earth |
| Price | 30–50% less expensive | More costly due to rarity |
| Environmental Impact | Lower | Higher due to mining |
| Ethical Concerns | Conflict-free | Possible involvement in conflict |
| Inclusions | Fewer or more uniform | More natural variations |
| Resale Value | Currently lower | Traditionally higher |
Price Comparison: Lab Grown vs Natural
One of the most significant reasons buyers consider lab diamonds is their price point. A lab grown diamond can be up to 50% cheaper than its natural counterpart with the same cut, clarity, carat, and color.
This pricing difference allows you to either save money or invest in a larger or higher quality diamond for the same budget. For example, a 1-carat natural diamond may cost $6,000, while a lab grown diamond of similar quality might cost only $3,000.
Environmental and Ethical Considerations
If you’re concerned about sustainability, lab diamonds offer a clear advantage:
-
No mining: Lab-grown diamonds don’t involve blasting through the Earth, which reduces ecological disruption.
-
Energy usage: Although growing diamonds in a lab still uses energy, technological improvements are continually reducing the carbon footprint.
-
Conflict-free: Since they are not mined, lab diamonds avoid associations with blood diamonds or unethical labor practices.
In contrast, natural diamond mining can lead to deforestation, water pollution, and displacement of local communities.
Appearance: Can You Tell the Difference?
To the naked eye, even a trained gemologist may struggle to distinguish a lab grown diamond vs real diamond. They have identical refractive indexes, fire, brilliance, and overall sparkle.
The only way to reliably identify a lab-grown diamond is through specialized testing and grading reports that note its origin. This is why it’s critical to always purchase diamonds—lab or natural—with proper certification from reputable labs like GIA, IGI, or AGS.
Durability and Longevity
Diamonds, regardless of their origin, score a 10 on the Mohs scale of hardness, making them the hardest known natural material. That means lab diamonds are just as durable as mined ones and are suitable for daily wear in engagement rings and other jewelry.
In terms of longevity, both lab grown and natural diamonds will last forever with proper care.
Resale Value and Investment
One area where natural diamonds currently have the edge is resale value. Traditionally, natural diamonds retain their worth better in the secondhand market, partly due to their historical value and rarity.
That said, the resale market for lab diamonds is evolving. As these gems gain mainstream acceptance and the industry matures, we may see shifts in how they’re valued over time.
Public Perception: Changing Attitudes
A decade ago, the idea of wearing a lab diamond might have been controversial. Today, that has changed dramatically. With celebrities, influencers, and eco-conscious consumers embracing lab diamonds, the stigma is rapidly disappearing.
Many buyers even view lab grown diamond vs real diamond not as a competition, but as a choice based on values—do you prioritize tradition, or do you value innovation and ethics?
How to Choose Between Lab Grown and Natural Diamonds
Here’s a quick checklist to help you decide:
-
Go for a lab grown diamond if:
-
You want better value for money.
-
You prioritize sustainability and ethical sourcing.
-
You want a bigger or higher-quality diamond within your budget.
-
-
Choose a real diamond if:
-
You value tradition and resale potential.
-
You want a gem formed by nature over billions of years.
-
You’re investing in a piece with potential long-term market value.
-
Popular Settings for Lab Diamonds
Lab diamonds are incredibly versatile and can be featured in a wide variety of settings:
-
Solitaire: Showcases the gem’s brilliance without distractions.
-
Halo: A ring of smaller diamonds adds more sparkle.
-
Three-stone: Represents the past, present, and future.
-
Vintage: Intricate designs with a timeless feel.
Thanks to their affordability, you can often afford more elaborate settings when choosing a lab diamond.
Conclusion
Understanding the key differences between a lab grown diamond vs real diamond is essential when shopping for fine jewelry. Whether you’re buying an engagement ring, a gift, or a treat for yourself, knowing where your diamond comes from—and what it stands for—can make all the difference.
Lab diamonds offer incredible brilliance, ethical peace of mind, and unbeatable value. Real diamonds, on the other hand, offer history, tradition, and long-standing market appeal. The choice ultimately depends on your values, preferences, and budget.
Whichever path you choose, you’ll be wearing a gem that symbolizes beauty, love, and commitment—lab grown or mined from the Earth.
