The Canadian Gemmological Association (CGA) will work with Swedish-based Gemometrics to use its GemPen technology in what they are calling an ‘academic partnership’.

The GemPen uses Ultra Spectrum Optical Filtering (USOF) technology to determine whether a diamond is lab-created, and whether it has been colour-treated.

The agreement will help Canadian students keep up-to-date with the latest technology, said CGA, and it is hoped that the deal will pave the way for similar partnerships in other countries.


Donna Hawrelko, CGA president, commented: “With the rise of lab-created diamonds and lab enhancements, GemPen is providing the information that gemmologists need to make accurate appraisals and determinations of diamonds, the world’s most commonly used gemstones.”

Meanwhile, Daniel Smirat, CEO of Gemometrics, commented: “We want our clients to be able to understand the changing technology and stay ahead of the curve when it comes to identifying whether or not a gemstone has been grown in the laboratory or in the ground naturally.”

The CGA is also a partner of Gem-A, the Gemmological Association of Britain, a similar educational organisation. Read more about their pairing below:
