Gemmology is the science about gemstones.

One of the objectives of this website is to provide gemmologists from around the world with an opportunity to exchange information in a fast and efficient way. At the same time GEMOLOGY WORLD™ can serve as a resource for the general public to learn more about gems, diamonds and jewellery. Gemstones have intrigued mankind since early times in history.

Today new challenges have to be met by the professional gemmologist in detecting synthetic gem materials, colour enhanced and simulated gemstones, and most recently as reported in the news media – the colour enhancement of diamonds.

We hope that we can contribute to an international network of gemmologists in sharing information about all aspects of gemmology ranging from new gem deposits to innovative gem identification techniques.
