Diamond educational guides for jewelry professionals
Our resource center offers comprehensive guides on all aspects of natural diamonds, written by our gemologists and diamond experts.

Our guides cover: the 4 fundamental diamond criteria (carat, color, clarity, cut) with detailed explanations of each sub-grade; gemological certificates and how to read them (GIA, IGI, HRD); diamond fluorescence and its impact on appearance; fancy color diamonds and their specific grading; and the comparison between natural and lab-grown diamonds.
Each guide is available in French and English, with explanatory visuals and concrete examples from our catalog. These resources are freely accessible and regularly updated to reflect the latest developments in certification standards.
