Michel July 18, 2025

Have you heard about lab grown diamonds but aren’t sure if they’re the real deal? Or maybe you’re curious if they’re worth the hype? In recent years, lab grown diamonds have been turning heads in the jewelry world, shaking up traditions, and offering an alternative that’s both beautiful and budget-friendly.

If you’re considering a dazzling new ring, whether it’s an engagement sparkler or a simple wedding ring, understanding what lab grown diamonds really are—and if they’re worth your investment—is key. Let’s dive in and unpack everything you need to know.

Understanding Lab Grown Diamonds

What Exactly Are Lab Grown Diamonds?

Lab grown diamonds are authentic diamonds that are created in a controlled lab environment instead of being mined from the earth. Made from pure carbon, just like natural diamonds, they possess the same crystal structure, chemical composition, and physical properties.

How Are Lab Grown Diamonds Made?

There are two main ways to grow diamonds in the lab:

  • HPHT (High Pressure High Temperature): Mimics the extreme heat and pressure conditions that naturally form diamonds beneath the Earth’s crust.

  • CVD (Chemical Vapor Deposition): Uses a gas mixture that deposits carbon atoms onto a diamond seed layer, building the diamond atom by atom.

Lab Grown Diamonds vs Natural Diamonds: What’s the Difference?

While lab grown diamonds and natural diamonds are chemically identical, the main difference is their origin. Natural diamonds take millions of years to form naturally in the Earth, while lab grown diamonds can be created in a matter of weeks.

The Science Behind Lab Grown Diamonds

HPHT and CVD Methods Explained

Both methods produce real diamonds with the same hardness (10 on Mohs scale), brilliance, and durability as mined diamonds. HPHT creates diamonds by applying intense pressure and heat, whereas CVD grows the diamonds layer by layer in a vacuum chamber.

Quality and Certification

Just like natural diamonds, lab grown diamonds are graded by respected labs like GIA and IGI. This certification covers the 4Cs: Cut, Color, Clarity, and Carat, ensuring you get a quality gem.

Why Choose Lab Grown Diamonds?

Affordability: More Value for Less

One of the biggest perks of lab grown diamonds? They cost 30-50% less than natural diamonds of the same size and quality. That means you can get a bigger or higher-quality stone without stretching your budget.

Ethical and Environmental Benefits

Mining diamonds can lead to environmental destruction and ethical dilemmas. Lab grown diamonds avoid all this—they’re cruelty-free, sustainable, and have a far smaller carbon footprint.

Variety and Customization Options

Since lab diamonds are easier and faster to produce, jewelers can offer more unique shapes, sizes, and settings. This means more ways to personalize your lab grown diamond rings or simple wedding rings.
