What Is a Lab Grown Diamond?

A lab grown diamond is a real diamond created in a highly controlled laboratory environment using advanced technology that replicates nature's process.

The creation begins with a diamond seed—a thin sliver of diamond crystal. The seed is placed in a specialized growth chamber where, layer by layer, pure carbon crystallizes around it, forming a rough diamond crystal. Once fully grown, the diamond is cut and polished by expert artisans using the same techniques applied to mined diamonds.

The result? A diamond that is physically, chemically, and optically identical to one formed deep within the Earth—but created above ground in a matter of weeks rather than billions of years. New to lab-grown? Start with our Natural vs. Lab-Grown Diamonds guide.

Lab Grown vs Mined Diamonds

Lab grown diamonds are identical to mined diamonds in every measurable way—sharing the same chemical composition, crystal structure, and brilliance. The only difference? How they're created.

What sets lab grown diamonds apart is their exceptional value. You'll enjoy 60–85% savings compared to mined diamonds of equal quality, while often achieving superior purity and clarity. Many of our diamonds reach Type IIa purity—a level found in less than 2% of mined diamonds, the kind typically reserved for the world's most expensive stones.

With lab grown diamonds, you get more size, better quality, and greater sparkle for your budget—all while making a responsible choice for the planet. For an honest look at prices by carat, resale value, and certification, read our Natural vs. Lab-Grown Diamonds guide.

Lab Grown vs Diamond Simulants

Lab grown diamonds are real diamonds—not imitations. Diamond simulants like moissanite and cubic zirconia may look similar at first glance, but they're completely different materials with different properties. They lack the hardness, brilliance, and lasting value of an actual diamond.

A lab grown diamond, however, is a genuine diamond in every way. It has the same durability, fire, and sparkle as a mined diamond, with the added benefit of being an environmentally responsible choice.

When you choose a lab grown diamond, you're getting the real thing—not a substitute.

Lab Grown Diamonds FAQs

Yes, lab grown diamonds are 100% real diamonds. They have the exact same chemical composition (pure carbon), crystal structure, and physical properties as mined diamonds. The only difference is their origin—one is created in a lab, the other formed naturally underground.

Lab grown diamonds are created using two advanced methods. High Pressure-High Temperature
(HPHT) replicates the extreme heat and pressure that form diamonds deep within the Earth,
while Chemical Vapor Deposition (CVD) builds the diamond layer by layer from carbon-rich gas
in a vacuum chamber. Both start from a thin diamond seed and grow a genuine diamond in a
matter of weeks.

No, jewelers cannot tell the difference with the naked eye or standard gemological tools. Lab grown and mined diamonds are visually and chemically identical. Only specialized equipment can detect minor trace elements that identify a diamond's origin, which is why certification is important.

Lab grown diamonds typically cost 60–85% less than comparable mined diamonds of the same size, cut, color, and clarity. This means you can either save significantly or invest in a larger, higher-quality diamond for the same budget.

Yes, all our lab grown diamonds 0.25 carats and larger come with independent certification from reputable gemological laboratories like IGI (International Gemological Institute) or GIA (Gemological Institute of America). Each diamond is graded for the 4Cs—cut, color, clarity, and carat weight—and includes a laser inscription on the girdle with its certification number.

No, lab grown diamonds are just as durable as mined diamonds. With a hardness rating of 10 on the Mohs scale, they're the hardest natural material on Earth. Your lab grown diamond will maintain its brilliance and sparkle for a lifetime with proper care.

Yes, lab grown diamonds have a significantly smaller environmental footprint than mined diamonds. They require less land disruption, use less water, and produce fewer carbon emissions. Choosing a lab grown diamond is an eco-conscious decision that doesn't compromise on quality or beauty.

Lab grown diamonds are real diamonds, while moissanite and cubic zirconia are diamond simulants—different materials designed to look like diamonds. Simulants have different chemical compositions, hardness levels, and optical properties. Lab grown diamonds have the same durability, brilliance, and value as mined diamonds, while simulants do not.

Absolutely. Lab grown diamonds can be insured just like mined diamonds. Your certification documents provide all the information needed for insurance coverage. Many insurance companies offer the same policies for lab grown diamonds as they do for mined diamonds.

No diamond resells at retail price - natural or lab grown - so no diamond is a true
investment. But dollars-at-risk is what really matters, and lab grown wins there: paying
60-85% less up front means far less money on the line. The value of a lab grown diamond is
captured on day one, in a bigger, better stone for your budget - not years later at resale.
