At CGL, we understand well the importance of research in order to push forward the boundaries of knowledge. The diamond industry is not static, but rather a dynamic and constantly evolving business.

Although diamond cutting and polishing has been taking place for hundreds of years, there are continuous changes and innovations and part of the reason for that is the research that is undertaken by a broad range of institutions, particularly by gem labs.

Our research is targeted at developing ways to quickly identify diamonds and any problems or issues they may have.

We aim to find practical solutions as part of our research for our valued clients. If you have a question relating to a certain size, cut, color or clarity of a stone we are happy to provide our assistance which is based on the deep experience and skills of our staff. Please feel free to contact us with any questions you may have.
