Cosmo Dictionary of Gems and Gemology

This work provides encyclopedic coverage of terms and techniques related to gems and gemology. Each entry includes scientific and historical information. The volume’s strength lies in its comprehensive scope; it treats all aspects of gemology beginning with the gems themselves, elaborates on technical methods and procedures, and explicates professional terminology. The book will serve as an invaluable reference source for practitioners and serious scholars in the field. The second edition of Dictionary of Gems and Gemology is a comprehensive work aimed at gemologists, mineralogists, geologists, jewel dealers, industry and hobbyists. Toward fulfillment of our purpose of meriting the acceptance of this Dictionary as an international reference book for the gemological profession, criticism of the first edition was invited from the several outstanding gemologists, mineralogists and practical jewelers mentioned later in the preface. As a result errors of varying importance have been corrected; definitions have been clarified in the body of the Dictionary, while valuable additions to many of the definition will be found in the Addenda.
