Gemological Science International (GSI) has launched the very first educational course dedicated to laboratory-grown diamonds.

The course, named Laboratory-Grown Diamond Essentials, is an online offering that can be accessed anywhere in the world.

GSI hopes that it will tap into the recent trend for lab-grown diamonds, which consumers are increasingly favouring for their lesser environmental impact and greater affordability.


Alethea Inns, GSI’s chief learning officer, commented: “It is imperative that the jewelry industry has the ability to communicate about laboratory-grown diamonds confidently and with transparency.

“GSI as an expert laboratory in testing and detecting laboratory-grown diamonds is happy to share our knowledge with the industry.

“We’re excited that we can offer an online resource that any member of the industry will find value in referencing.”

As a global gemological organisation, GSI has graded and identified hundreds of thousands of laboratory-grown diamonds and its team of researchers and scientists have made several notable discoveries relating to laboratory-grown diamond identification.

President and co-founder, Debbie Azar, added: “There are many nuances when it comes to lab grown diamonds; from their growth methods and treatments, to understanding the various inclusions, color undertones and other factors – it’s not exactly the same as natural diamonds.”
