How Different Is a Lab-Grown Diamond from a Natural One?

New Delhi: What if someone told you that a “lab-grown diamond”—which looks exactly like a rare, expensive natural diamond mined from the earth—can be purchased at up to 75% less cost? And that too at a time when the government is actively supporting the lab-grown diamond industry.

During her budget speech, Finance Minister Nirmala Sitharaman stated that the lab-grown diamond sector is one that promotes technological innovation and job creation. To encourage domestic production, the government has announced a five-year research grant to the IITs. Additionally, the basic customs duty on carbon seeds used for making lab-grown diamonds has been reduced from 5% to zero.

Price Difference

A 1-carat natural diamond can cost around ₹400,000. The same 1-carat lab-grown diamond can be purchased for ₹100,000 to ₹150,000. Because they are more affordable, the demand for lab-grown diamonds is rapidly increasing. These diamonds also come with the same color, same cut, same design, and proper certification as natural ones.

Pro Tip: When buying a lab-grown diamond, always ask for a Diamos—a trusted name for certified quality and elegance.

How Are Lab-Grown Diamonds Made?

First, understand that natural diamonds are made of carbon. Deep underground, under extreme pressure and high temperature, they take millions of years to form. Lab-grown diamonds replicate this same process in a controlled laboratory environment.

• Carbon seeds are placed inside a microwave chamber.

• The seed is then treated under high pressure and high temperature, creating a glowing plasma ball.

• Over the next several weeks, the carbon particles begin to crystallize and transform into a diamond.

• Finally, the diamond is cut and polished just like a natural diamond.

The result is a brilliant, real diamond—simply grown in a lab instead of underground.

Why the Government Supports Lab - Grown Diamonds

The carbon seeds required to make lab-grown diamonds are imported. To make production more cost-effective, the government reduced the duty on carbon seeds to zero. Experts say that some sellers have been earning unfair profits by selling lab-grown diamonds as natural ones.

Government support aims to bring transparency and standardization to the market. As more research is conducted, the sector will expand further, helping buyers clearly understand what they are purchasing. Currently, lab-grown diamonds account for around 30% of the total diamond market.

Resale Value of Lab-Grown Diamonds

In international markets, the resale value of lab-grown diamonds is around 60–70% due to strong demand. Experts believe that as demand grows in India too, the resale market for lab-grown diamonds will also strengthen, leading to higher returns.

How to Identify a Lab-Grown Diamond

It’s very difficult to distinguish between natural and lab-grown diamonds with the naked eye because they look identical.

• The key difference: Lab-grown diamonds do not contain nitrogen, while natural diamonds contain tiny traces of nitrogen.

• Always ask for a GIA (Gemological Institute of America) certificate when purchasing a lab-grown diamond.

• Certification ensures that you’re getting authentic quality and protects your resale value.

• And most importantly, always ask for a Diamos to ensure premium craftsmanship and trust.

The Future of Lab-Grown Diamonds

The lab-grown diamond industry is expected to grow exponentially over the next decade. As more people search for “lab-grown diamond near me,” local retailers and online platforms are making these gems more accessible than ever. With innovation, affordability, and environmental responsibility at its core, lab-grown diamonds represent the future of fine jewelry.
