Earth Mined Diamonds vs. Lab Diamonds: What’s the Real Difference?

Introduction 

Diamonds are forever—but not all diamonds have the same story. If you’ve been shopping for an engagement ring or a special piece of jewelry, you’ve probably heard the terms “earth mined diamonds” and “lab diamonds.” What’s the real difference? Is one better than the other? And how do you choose what’s right for you? Let’s dig deep (pun intended!) into the sparkling world of diamonds and uncover the truth behind these two dazzling options. 

 

What Are Earth Mined Diamonds? 

Earth mined diamonds, sometimes called natural diamonds, have been forming beneath the earth’s surface for billions of years. Through intense heat and pressure, carbon atoms bond in a crystal structure, eventually making their way to the surface via volcanic eruptions. Here’s what you should know: 

  • Origin: Created naturally over millions to billions of years deep within the earth. 

  • Discovery: Extracted from mines around the world—think Africa, Russia, Canada, and Australia. 

  • Uniqueness: Each diamond is one-of-a-kind, shaped by nature’s unpredictable hand. 

  • Certification: Graded and certified by reputable labs like GIA or AGS. 

 

What Are Lab Diamonds? 

Lab diamonds, also known as lab grown or man-made diamonds, are created above ground in high-tech labs. Scientists mimic the natural diamond-forming process using either High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD). The result? A diamond that’s chemically, physically, and optically identical to its earth mined cousin. 

  • Origin: Produced in a laboratory in weeks or months. 

  • Process: Grown from a tiny diamond “seed” under controlled conditions. 

  • Consistency: Often have fewer inclusions and more predictable quality. 

  • Certification: Also graded and certified by the same labs as earth mined diamonds. 

 

Earth Mined Diamonds vs. Lab Diamonds: The Key Differences 

Let’s break it down: 

Feature 

Earth Mined Diamonds 

Lab Diamonds 

 

Origin 

Formed naturally in the earth 

Grown in a lab 

 

Time to Create 

Millions to billions of years 

Weeks to months 

 

Environmental Impact 

Mining can affect ecosystems 

Lower environmental footprint 

 

Price 

Typically, more expensive 

20-40% less expensive 

 

Resale Value 

Traditionally holds value better 

Resale market still evolving 

 

Inclusions 

Nature-made imperfections 

Often fewer, more consistent 

 

Ethics 

Concerns over “conflict diamonds” 

Generally considered conflict-free 

 

 

Appearance: Can You Tell the Difference? 

Here’s the kicker: 

To the naked eye, no. Even most jewelers need specialized equipment to distinguish between earth-minded diamonds and lab diamonds. Both sparkle, both shine, and both can be cut into any shape or style you love. 

  • Color and Clarity: Both can achieve top grades. 

  • Brilliance: Both refract light beautifully. 

  • Variety: Available in all shapes—round, princess, cushion, and more. 

 

Value and Investment

 Let’s talk money—because, hey, it matters. 

  • Earth Mined Diamonds: Historically, these diamonds have held their value better over time. They’re seen as rare and, for some, as an investment. 

  • Lab Diamonds: More affordable up front (sometimes 20-40% less for the same size and quality), but resale value is still a developing market. 

If you’re buying for sentiment, beauty, or budget, lab diamonds are a fantastic option. If you’re thinking of long-term investment, earth mined diamonds might have the edge. 

 

Ethics and the Environment 

  • Earth Mined Diamonds: Mining can come with environmental challenges—land disruption, water use, and, in some regions, human rights concerns. However, many jewelers (like us!) are committed to sourcing conflict-free diamonds. 

  • Lab Diamonds: Created in controlled environments, lab diamonds are generally considered more eco-friendly and conflict-free. For the eco-conscious or ethically minded shopper, this is a big plus. 

 

Which Should You Choose? 

Still torn? Here’s a quick guide: 

Choose Earth Mined Diamonds If: 

  • You value rarity and tradition. 

  • You want a stone with a story billions of years in the making. 

  • Investment value is important to you. 

Choose Lab Diamonds If: 

  • You want the biggest sparkle for your buck. 

  • You’re focused on environmental and ethical concerns. 

  • You love innovation and modern technology. 

 

FAQs: Earth Mined Diamonds vs. Lab Diamonds 

Are lab diamonds real diamonds? 

Absolutely! Lab diamonds are chemically and physically identical to earth mined diamonds. 

Will people know if my diamond is lab grown? 

Nope! Unless you tell them, no one can tell just by looking. 

Do lab diamonds come with certifications? 

Yes, top labs like GIA and IGI certify lab diamonds just like earth mined stones. 

Are lab diamonds cheaper? 

Generally, yes—often 20-40% less for comparable size and quality. 

Are earth-mined diamonds better quality? 

Not necessarily. Both can be flawless or included, colorless or tinted. It comes down to the individual stone. 

What about “conflict diamonds”? 

We take pride in sourcing only conflict-free earth mined diamonds. Lab diamonds are inherently conflict-free. 

Can you get custom jewelry with either type? 

Absolutely! At Professional Jewelers, you can design your dream ring or jewelry with either earth mined or lab diamonds—online or in-store.
