What are Lab-Grown Diamonds?

They are not “fakes,” imitations, or look-alikes such as cubic zirconia. A lab-grown diamond is physically, chemically, and optically identical to a diamond mined from the earth. They have the same carbon atom structure, the same hardness, and the same magnificent sparkle.

Let’s start with the most important fact: Lab-grown diamonds are 100% real diamonds.

Frequently Asked Questions.

What is a lab-Grown diamond?

A lab-grown diamond is a real diamond created in a highly controlled, state-of-the-art laboratory. Using advanced technology (like HPHT or CVD), scientists replicate the exact conditions of extreme heat and pressure that form diamonds deep within the earth. It is not a "fake" diamond or a simulant like cubic zirconia.

Are lab-Grown diamonds "real" diamonds?

Yes, absolutely. They are 100% real diamonds. They have the exact same chemical composition, crystal structure, and optical properties as a mined diamond. Even an expert gemologist cannot tell the difference with the naked eye. They are just as hard (a 10 on the Mohs scale) and will sparkle with the same brilliance and fire, for a lifetime.

hat are the main benefits of choosing a lab-grown diamond?

There are two primary benefits:

  • Exceptional Value: A lab-grown diamond typically costs significantly less than a mined diamond of the exact same size and quality. This often allows you to choose a larger or higher-quality stone (better cut, colour, or clarity) while staying within your budget.
  • Traceability & Ethics: Because they are made in a lab, their origin is 100% known. This makes them a sustainable and ethical choice, completely free from the environmental and humanitarian concerns that can be associated with traditional mining.
Are lab-grown diamonds graded the same way as mined diamonds?

Yes. Lab-grown diamonds are independently graded and certified by the world's leading gemological labs (like the GIA and IGI) using the exact same standard as mined diamonds: The 4 Cs (Cut, Colour, Clarity, and Carat). You can be completely confident in the quality of your stone, which is why we created our Guide to the 4 Cs of Lab-Grown Diamonds.
