About Jewellery

Lab-grown diamonds are chemically and optically identical to diamonds mined from the Earth.

The only practical difference lies in their origin; one was created naturally millions of years ago underground, and the other in a laboratory only months ago.

Otherwise, both are cut and polished using the same techniques and are graded according to the same criteria.

Specialized gemological equipment is required to tell them apart, as no difference is visible to the naked eye.

How can you tell if a diamond is natural or lab-grown?

Only a qualified gemologist can distinguish between a natural diamond and a lab-grown diamond through inspection.

The best way to know the difference is to purchase a certified diamond from an accredited laboratory such as GIA or IGI.

What is an IGI or GIA certificate for a lab-grown diamond?

IGI (International Gemological Institute) and GIA (Gemological Institute of America) are the leading gemological laboratories that grade and certify diamonds.

Both issue certificates that assess diamonds, whether natural or lab-grown, according to the four main criteria (cut, color, clarity, and carat weight).

Certificates also provide detailed information on proportions, inclusions, fluorescence, and symmetry.
