Top 5 Myths About Lab-Grown Diamonds – Busted!

Lab-grown diamonds are one of the most talked-about innovations in the jewelry world — yet they remain surrounded by myths and misconceptions. From questions about their quality to doubts about their value, it's time to clear the air with facts. Here are the top 5 myths about lab-grown diamonds, debunked once and for all.

Myth 1: Lab-Grown Diamonds Are Fake

Truth: Lab-grown diamonds are 100% real diamonds. They share the exact same chemical composition (pure carbon), crystal structure, and physical properties as mined diamonds. The only difference is their origin — a laboratory instead of the Earth's mantle.

They are not simulants like cubic zirconia or moissanite. Lab-grown diamonds pass every standard diamond tester and are indistinguishable from mined diamonds to the naked eye.

Myth 2: Lab-Grown Diamonds Are Low Quality

Truth: Lab-grown diamonds are graded on the exact same 4Cs — Cut, Colour, Clarity, and Carat — as natural diamonds. In fact, because they are grown in controlled environments, many lab-grown diamonds achieve higher clarity grades than mined stones.

Every Raro Jewels lab-grown diamond is IGI or GIA certified, giving you a full grading report and complete transparency on quality.

Myth 3: Lab-Grown Diamonds Don't Last

Truth: Diamonds — lab-grown or mined — are the hardest natural substance on Earth, rating 10 on the Mohs hardness scale. A lab-grown diamond will not fade, scratch, or deteriorate over time. It is built to last generations, just like any natural diamond.

Whether set in a ring, pendant, or a pair of lab-grown diamond earrings, the durability remains exactly the same.

Myth 4: Lab-Grown Diamonds Are Easy to Spot

Truth: Even trained gemologists and professional jewelers cannot tell the difference between a lab-grown and a mined diamond with the naked eye. Advanced laboratory equipment is required to identify the origin of a diamond.

This is precisely why reputable grading institutes like IGI and GIA certify lab-grown diamonds separately — to ensure full transparency for consumers. Learn more about our certification process.

Myth 5: Lab-Grown Diamonds Have No Value

Truth: Lab-grown diamonds hold real emotional, aesthetic, and resale value — just like mined diamonds. Their value is determined by the same 4Cs grading standards. More importantly, they offer 30–60% more diamond for the same budget, making them a smarter investment for buyers who prioritise size, quality, and ethics.
