Lab Diamonds vs Real Diamonds

When shopping for a diamond, you’ll likely come across two main options: lab-grown diamonds and natural diamonds. While both are real diamonds, their differences go beyond just how they are formed. Questions like:

  • Are lab diamonds as durable as natural diamonds?

  • Can you tell the difference between lab and natural diamonds?

  • Do lab-grown diamonds hold their value?

  • Which one is the better investment?

  • Do both lab and natural diamonds get GIA certification?

…all come up when deciding between the two. If you’re trying to figure out which is the right choice for your engagement ring, wedding band, or fine jewelry, we’ve got you covered.

At Worthmore Jewelers, we’re here to break it all down in detail, tackling every question you might have so you can make the best choice.

Are Lab Diamonds and Natural Diamonds the Same?

Yes, lab-grown diamonds are real diamonds.

Lab and natural diamonds have the same chemical composition, optical properties, and hardness. They both:

  • Are made of pure carbon.

  • Rank 10 on the Mohs scale of hardness (the hardest gemstone).

  • Sparkle and reflect light in the same way.

  • Can be cut, polished, and set in any type of fine jewelry.

The only difference? Their origin.

  • Natural diamonds form under immense heat and pressure deep within the Earth over billions of years.

  • Lab diamonds are created in weeks using advanced technology that replicates the natural process.

If you place a natural diamond and a lab-grown diamond side by side, even a jeweler can’t tell the difference without special equipment.

How Are Lab Diamonds Made?

Unlike natural diamonds, which take billions of years to form, lab-grown diamonds are created in a controlled environment in a matter of weeks.

  • HPHT (High-Pressure, High-Temperature) – Mimics the heat and pressure found deep in the Earth’s mantle.

  • CVD (Chemical Vapor Deposition) – Uses carbon-rich gases to grow the diamond layer by layer.

Worthmore Tip: Lab diamonds should not be confused with diamond simulants like cubic zirconia or moissanite, which are completely different materials.

Lab Diamonds vs. Natural Diamonds: A Complete Comparison

While lab and natural diamonds look the same, there are some key differences to consider.

1. Pricing & Affordability

  • Lab Diamonds: Usually 30-50% less expensive than natural diamonds of the same size and quality.

  • Natural Diamonds: More expensive due to their rarity and formation process.

Which to Choose? If budget is a major factor, lab diamonds allow you to get a larger stone for the same price.

2. Rarity & Formation

  • Natural Diamonds: Formed 1 to 3 billion years ago under extreme heat and pressure.

  • Lab Diamonds: Created in weeks inside a controlled environment.

Which to Choose? If you love the romantic history of a billion-year-old gemstone, a natural diamond is the way to go.

3. Resale Value & Investment

  • Lab Diamonds: Have little to no resale value since they can be endlessly produced.

  • Natural Diamonds: Retain some resale value, especially high-quality stones.

Which to Choose? If you see your diamond as an heirloom piece, a natural diamond might be the better investment.

4. Can You Tell the Difference?

No! Even experienced jewelers need special tools to distinguish between lab and natural diamonds.

  • Lab diamonds have microscopic laser inscriptions that identify them as lab-grown.

  • Advanced testing can reveal growth structures unique to each type.

Worthmore Tip: Always ask for a certification (GIA, IGI, or AGS) to confirm whether your diamond is natural or lab-grown.

Common Questions About Lab & Natural Diamonds

1. Do Lab Diamonds Hold Their Value Over Time?

  • Lab diamonds generally depreciate in value because they can be mass-produced.

  • Natural diamonds tend to hold more value due to their rarity and demand.

2. Are Lab Diamonds as Durable as Natural Diamonds?

Yes! Both are equally hard and scratch-resistant.

  • Lab and natural diamonds last forever with proper care.

  • Both can be resized, reset, or passed down for generations.

3. Can Lab Diamonds Be Insured?

Yes! Lab-grown diamonds can be appraised and insured just like natural diamonds.

Most insurance companies cover lab diamonds under the same policies as natural ones.

4. Are Lab Diamonds Certified?

Yes! The GIA (Gemological Institute of America) and IGI (International Gemological Institute) certify lab diamonds.

A GIA or IGI certification confirms the diamond’s authenticity, quality, and origin.

Can Lab Diamonds Be Used in Engagement Rings?

Yes! Lab-grown diamonds are a popular choice for engagement rings and can be used in any setting, just like natural diamonds.

  • Classic Solitaire Rings – A single lab diamond set in gold or platinum for timeless elegance.

  • Halo & Vintage Designs – Lab diamonds in intricate settings enhance their sparkle and charm.

  • Three-Stone & Custom Rings – A meaningful choice to symbolize past, present, and future with precision-cut lab diamonds.

Whether you prefer a minimalist style or a bold statement piece, lab-grown diamonds offer the same beauty and romance for your engagement ring.

What Other Types of Jewelry Can Lab Diamonds Be Used In?

Lab diamonds aren’t just for engagement rings—they’re used in a wide variety of fine jewelry.

  • Wedding Bands & Eternity Rings – Lab diamonds create dazzling wedding bands with continuous sparkle.

  • Diamond Earrings – From classic studs to intricate chandelier earrings, lab diamonds add brilliance to any look.

  • Tennis Bracelets & Necklaces – A seamless row of lab diamonds delivers high-impact shine.

  • Statement Rings & Fashion Jewelry – Lab diamonds can be set into bold, artistic designs that turn heads.

No matter the occasion, lab diamonds can be incorporated into virtually any jewelry style with breathtaking results.

Should You Choose a Lab Diamond or a Natural Diamond?

Both lab and natural diamonds have pros and cons, so the best choice depends on your priorities:

Choose a Lab Diamond If You Want:

  • A bigger diamond for your budget.

  • A modern, ethical, and affordable alternative.

  • A diamond that is visually identical to a natural one.
