5 Myths About Lab-Grown Diamonds

5 Myths About Lab-Grown Diamonds – Debunked by ONYA

Lab-grown diamonds, also called man-made diamonds or engineered diamonds, are taking the jewelry world by storm. They’re real diamonds, grown in advanced labs instead of mined from the earth. Yet, despite their growing popularity, many myths and misconceptions about lab-grown diamonds persist, confusing buyers.

In this article, we’ll debunk the top 5 myths about lab-grown diamonds so you can make an informed, confident choice.


1. Myth: Lab-Grown Diamonds Are Fake

Many people assume lab-grown diamonds are fake, like cubic zirconia or moissanite. The truth? Lab-grown diamonds are 100% real diamonds. They share the same chemical composition, hardness, brilliance, and sparkle as mined diamonds.

The only difference is origin: one is formed deep underground over billions of years, while the other is grown in a lab using advanced technology like CVD (Chemical Vapor Deposition) or HPHT (High Pressure High Temperature).


2. Myth: Lab-Grown Diamonds Don’t Last

Some believe man-made diamonds won’t stand the test of time. In reality, they rank a 10 on the Mohs hardness scale same as mined diamonds.

This means lab-created diamonds are just as durable and resistant to scratching, chipping, or wear. With proper care, they’ll last for generations, making them perfect for engagement rings, wedding bands, or heirloom jewelry.


3. Myth: Lab-Grown Diamonds Have No Value

It’s often claimed that lab-grown diamonds don’t hold value. While resale prices can differ from mined diamonds, their true value lies in affordability and accessibility.

With lab-grown diamonds, you can often buy a larger or higher-quality stone at a lower price compared to mined diamonds. As more consumers embrace sustainable and ethical choices, the demand for lab-grown diamonds is only increasing.

4. Myth: Lab-Grown Diamonds Aren’t Eco-Friendly

Another misconception is that creating diamonds in labs harms the planet just as much as mining because it needs a lot of power.
Lab-grown diamonds avoid the environmental destruction of mining, such as deforestation, soil erosion, and water pollution.

Many producers are now using renewable energy to further reduce their carbon footprint, making lab-grown diamonds one of the most sustainable and ethical choices in fine jewelry.


5. Myth: You Can Easily Spot the Difference

A big myth is that lab-grown diamonds “look different” from mined ones. The truth is, even trained gemologists can’t tell them apart without specialized heavy machinery.

Lab-grown diamonds have the same fire, brilliance, and sparkle as natural diamonds. To the naked eye, they are identical it’s only their origin that differs.
