Résumé

Since Gemmology was first published, thousands of readers have used it to gain an in-depth appreciation of the science of gemmology, its history and practice. This third edition has been completely revised to cover the latest methods of gem enhancement and identification, as well as the most up to date test instruments and laboratory techniques. It includes details of the Gemmological Associations recently introduced Foundation course, and even provides sample examination questions.
