About

We at GSI have a vision: to create a modern, state-of-the-art diamond grading lab that takes advantage of the latest breakthroughs in diamond grading. To do this, we reengineered the diamond grading process and founded it on foolproof cutting-edge technology and automation. The result is diamonds that are graded to the highest standards. Proprietary software is at the heart of GSI’s diamond grading process. This state-of-the-art software reduces the chances of human error by automating the grading process. The same ethos behind our grading philosophy guides our global expansion efforts and informs the interactions between our offices. All our offices constantly exchange information and knowledge, allowing us to continually improve our operations and ensure the highest quality of diamond grading.
