Lab grown diamonds have taken over the jewellery world, and for good reason. They’re beautiful, affordable, sustainable—and yet, many people still ask the big question: “Are lab grown diamonds really real?”

If you’ve been confused by mixed information online, this guide breaks down the biggest myths and the real facts behind lab grown diamond jewellery.

Myth 1: Lab Grown Diamonds Are Fake

Fact:

Lab grown diamonds are 100% real diamonds.

They have the same chemical, optical, and physical properties as natural diamonds. The only difference is where they are created—one forms underground over billions of years, the other grows in a controlled lab environment.

They’re so real that even professional jewellers need special equipment to tell the difference.

Myth 2: Lab Grown Diamonds Are Not Valuable

Fact:

Lab grown diamonds hold value—just differently.

Yes, they cost 30–70% less than natural diamonds, but that doesn’t make them worthless. Their value comes from:

Premium quality at a lower price
Ethical sourcing
Environmental sustainability
Trend popularity

For people who care about beauty and budget, lab diamonds are a smart and valuable choice.

Myth 3: Lab Grown Diamonds Look Different

Fact:

Visually, you cannot tell a lab grown diamond from a natural one.

Both shine with the same brilliance and fire. Whether it’s a ring, pendant, bracelet, or earrings, lab grown jewellery looks just as stunning—sometimes even better because you can afford higher clarity and color grades for the same price.

Myth 4: Lab Diamonds Are “Synthetic” or “Cubic Zirconia”

Fact:

No—they are not the same.

Cubic zirconia and moissanite are diamond alternatives, but lab grown diamonds are real diamonds, grown using:

HPHT (High Pressure High Temperature)
CVD (Chemical Vapor Deposition)

Both techniques replicate the natural diamond-growing process.

Myth 5: Lab Grown Diamonds Are Bad for the Environment

Fact:

Lab grown diamonds are actually far more eco-friendly.

Natural diamond mining requires huge amounts of land, energy, and water. Lab grown diamonds reduce:

Soil disturbance
Water usage
Carbon footprint

Many labs even use renewable energy to grow diamonds.

Myth 6: Lab Grown Diamonds Won’t Last Long

Fact:

Lab grown diamonds are just as durable as natural diamonds.

Diamonds (lab or mined) score 10 on the Mohs hardness scale, making them the hardest known natural material. Your lab grown diamond jewellery will last a lifetime—and beyond.
