So... what are lab-grown diamonds, exactly?
A lab-grown diamond is a real diamond, just created in a high-tech lab by humans instead of deep underground by nature. Same chemical composition, same strength, same sparkle as a natural diamond; the only difference is their origin (and price tag!).
Are lab-grown diamonds “real” diamonds?
Yes! Lab-grown diamonds are 100% real diamonds. They’re optically, physically, and chemically identical to natural ones. They’re not simulants or “fakes” like CZ (cubic zirconia) or moissanite — they’re the real deal. The only difference is where they were formed.
Can anyone tell the difference between a natural and lab-grown?
No, not without specialized equipment. Even professional jewelers need specialized equipment to spot the difference. To the naked eye, a lab-grown diamond looks every bit as brilliant as a natural one, because after all, it IS a diamond.
Why are lab-grown diamonds more affordable?
Unlike the unpredictable and inconsistent circumstances found in nature, humans can create the perfect conditions for diamonds in a lab, which allows us to better control the quantity and quality produced. This
means you can enjoy a larger or higher-quality diamond for your budget —
without compromising beauty or quality.
Can lab-grown diamonds come with certificates?
Absolutely. Just like natural diamonds, lab-grown diamonds can
be graded and certified by independent gemological labs, such as GIA and IGI.
Can I insure or appraise a lab-grown diamond?
Yes. You can insure, appraise, and care for your lab-grown diamond just like a natural one.
Are lab-grown diamonds good for engagement rings?
Oh yes. In fact, lab-grown diamonds are the modern choice for engagement rings. In 2024, over 52% of engagement rings were lab-grown. Stunning, responsible, and easy on the budget. You get the sparkle you love, plus a little extra room in the honeymoon fund.
Do lab-grown diamonds come in all shapes and sizes?
Yes! From timeless round brilliants to unique ovals, emerald cuts, and cushions: lab-grown diamonds are available in every shape and carat weight you can imagine. If you can dream it, we can probably find it (and likely on sale).
How should I care for my lab-grown diamond?
The same way you care for a natural diamond, because once again it IS a diamond. Clean it with warm soapy water and a soft brush. And pop by the store anytime for a complimentary check — we love seeing our jewelry out in the wild.
What are the physical properties of a natural vs lab-grown diamonds?
Lab-grown diamonds possess the same chemical properties and hardness as naturally mined diamonds. Since they are the same, lab-grown diamonds are subject to the same “four C’s” often used to reference quality of a diamond— cut, color, clarity and carat — grading system as natural gems.
