Are Lab Grown Diamonds as Strong as Real Diamonds?

Lab-grown diamonds have taken the jewelry world by storm, offering the same dazzling brilliance as natural diamonds. But when it comes to strength and durability, how do they really compare? If you’re considering a lab-grown diamond engagement ring, a statement piece, or an everyday luxury, understanding how strong lab-grown diamonds are is key to making the right choice.

In this guide, we’ll break down whether lab-grown diamonds match natural diamonds in hardness, toughness, and longevity, and answer related questions about durability, care, and best choices for different jewelry settings.

Do Lab-Grown Diamonds Have the Same Strength as Natural Diamonds?

A diamond’s strength is measured by its hardness, toughness, and durability:

  • Hardness – How well a diamond resists scratches (measured on the Mohs scale).

  • Toughness – The ability to withstand chips, cracks, or breakage under impact.

  • Durability – How well the diamond retains its brilliance over time.

Lab-grown diamonds and natural diamonds have the exact same atomic structure, making them equally strong in all three areas.

Are Lab-Grown Diamonds Just as Hard as Natural Diamonds?

Yes—lab-grown diamonds are just as hard as natural diamonds.

  • Both rank 10 on the Mohs hardness scale, meaning they can only be scratched by another diamond.

  • They are harder than all other gemstones, including sapphires, rubies, emeralds, and moissanite.

  • Their resistance to scratches and abrasions makes them perfect for daily wear in rings, bracelets, and earrings.

Hardness matters because it ensures your diamond remains flawless and free from surface scratches, even with everyday use.

Can Lab-Grown Diamonds Chip or Break?

While diamonds are the hardest natural material, they are not unbreakable—this applies to both natural and lab-grown diamonds.

  • Chipping risk depends on the cut and setting. Certain shapes, like pear and marquise, have delicate points that need protection.

  • Toughness varies across cuts. Round and cushion cuts are more resistant to chipping due to their smooth edges.

  • A secure setting helps. Choosing a halo or bezel setting adds extra protection to avoid accidental impact damage.

Lab-grown diamonds are just as tough as natural diamonds, but proper care and the right setting can further reduce chipping risks.

How Long Do Lab-Grown Diamonds Last?

A common question is whether lab-grown diamonds will wear down or lose their sparkle over time. The answer? No—they last forever.

  • They do not fade, discolor, or weaken over time.

  • Their brilliance remains the same as long as they are properly cleaned and maintained.

  • They require the same care as natural diamonds to stay in perfect condition.

Your lab-grown diamond will remain flawless for a lifetime, just like a natural diamond.

What to Look for When Buying a Lab-Grown Diamond

To ensure you’re getting a high-quality, long-lasting lab-grown diamond, look for:

  • Certification – Only choose GIA or IGI-certified diamonds to guarantee authenticity.

  • Cut Quality – A well-cut diamond reflects more light, enhancing its brilliance.

  • Clarity & Color – Opt for VS clarity or higher and a near-colorless grade for optimal beauty.

  • Secure Settings – Prong and bezel settings help protect against accidental chips.

  • Earrings – Perfect for everyday studs or elegant drop earrings.
