Lab-grown diamonds are real diamonds created in a laboratory setting using cutting-edge technology. They share the same chemical, physical, and optical properties as mined diamonds, but typically have a smaller environmental impact.

Yes. Lab-grown diamonds are real, certified diamonds, identical in composition and brilliance to mined diamonds. The main difference lies in their origin: a controlled laboratory vs. underground mining.

Lab-grown diamonds are more eco-friendly, free of conflict concerns, and often offer better value for the same carat size and quality compared to mined diamonds. They’re also traceable, so you know the exact origin and creation process.

Generally, lab-grown diamonds are priced 20–40% lower than mined diamonds of comparable size and quality. This cost advantage allows for larger or higher-quality stones at more accessible price points.

Absolutely. Lab-grown diamonds are insurable just like mined diamonds. Most insurance providers treat them the same, as they hold intrinsic value and can be appraised.

Specialized diamond testers and gemological labs can determine the growth origin. A lab-grown diamond will often come with a certificate explicitly stating it is lab-grown.

Yes. Major gemological labs like GIA (Gemological Institute of America) and IGI (International Gemological Institute) issue certificates for lab-grown diamonds, detailing the 4Cs (Cut, Color, Clarity, and Carat).

The 4Cs stand for Cut, Color, Clarity, and Carat weight. They are universal metrics to evaluate a diamond’s quality and guide pricing, whether it’s lab-grown or mined.

We include an official lab certificate for each Lark & Berry diamond piece, ensuring full transparency about its characteristics and origin.

Lab-grown diamonds can achieve the same clarity grades as mined diamonds. Their inclusions are usually fewer or more uniform, but every stone is still unique.

No. Lab-grown and mined diamonds both rank 10 on the Mohs hardness scale, making them equally durable for everyday wear.

Any diamond shape or cut can be lab-grown, including round brilliant, princess, cushion, oval, emerald, pear, and more. Lark & Berry offers a wide selection to suit your style.

They are generally considered more ethical because they avoid many of the social and environmental challenges associated with mining. There’s also clear traceability, ensuring conflict-free sourcing.

Lark & Berry partners with sustainable suppliers and adheres to strict environmental standards. Many of our lab-grown diamonds come with independent certifications verifying ethical and eco-friendly production.

Lab-grown diamonds require significantly less energy and water than mining operations, reducing land disturbance and carbon emissions. Plus, controlled lab conditions often utilize renewable energy sources.

“Conflict-free” means no proceeds fund illegal or violent activities. “Ethical” also accounts for broader labor, environmental, and socio-economic conditions. Lark & Berry’s diamonds satisfy both criteria.
