Book Description
Beginner's Guide to Gemmology presents the profiles of the principal gem materials. This book discusses the interesting characteristics of gemstones as the growing consumer market jewelry resulted in increased sales of gem testing instruments. Organized into 12 chapters, this book begins with an overview of the development of the science of gemmology. This text then explains the fundamental qualities necessary in a gem, including color, hardness, specific gravity, crystallography, refractive index, pleochroism, critical angle, luminescence, and absorption spectra. Other chapters consider the organic gem materials, including amber, ivory, coral, tortoiseshell, jet, ebony, and pearl. This book discusses as well the various methods used in the production of man-made gemstones and the commercial use in gem testing. The final chapter deals with the composition of synthetic gemstones. This book is a valuable resource for gemmologists and jewelers. Students who intend to become a qualified gemologist will also find this book extremely useful.

Book Description
The chapters contributed to this book recognize the important and diverse contributions of mineralogy to the valorization, characterization, interpretation and conservation of cultural heritage. The book focuses on examples of materials and methodological issues rather than technical/analytical details.

Book Description
This edited collection is an interdisciplinary study of gems in the early modern world. It examines the relations between the art, science, and technology of gems, and it does so against the backdrop of an expanding global trade in gems. The eleven chapters are organised into three parts. The first part sets the scene by describing how gems moved around the early modern world, how they were set in motion, and how they were pulled together in the course of their travels. The second part is about value. It asks why people valued gems, how they determined the value of a given gem, and how the value of a gem was connected to its perceived place of origin. The third part deals with the skills involved in cutting, polishing, and mounting gems, and how these skills were transmitted and articulated by artisans. The common themes of all these chapters are materials, knowledge and global trade. The contributors to this volume focus on the material properties of gems such as their weight and hardness, on the knowledge involved in exchanging them and valuing them, and on the cultural consequences of the expanding trade in gems in Eurasia and the Americas.

Book Description
Gemstones is the first attempt in English to bring together the geological, mineralogical and gemmological developments that have taken place during the last thirty years. Though there have been many gemstone books published in that time, most have been concerned, understandably and rightly, with the science of gem testing and have covered that area very well. Details of the geological occurrence of many of the classic gemstones, and of nearly all those which have only recently been discovered, have been less adequately dealt with. Coverage has been restricted to a number of papers in a wide variety of geological and mineralogical journals. Gemstones hopes to get the balance right. In the preparation of the book all the journals and monographs in the field have been consulted so that the book should stand for some years as the authority to which gemmologists and others turn in the first instance. Ease of reference and depth of coverage make Gemstones both a reference book and a bench book. Acknow ledgements I am grateful to Brian Jackson of the Department of Geology, Royal Museums of Scotland who read the manuscript and painstakingly indicated places where amendment or alteration was needed. I am also grateful to the publishers of the books on which the line illustrations are based. The colour plates present in the book derive from a number of sources, which I would like to acknowledge as follows. Plates 1, 4-15 and 17 Crown copyright reserved.

Book Description
This collection stems from the International Association of Societies of Design Research (IASDR) congress in 2021, promoting the research of design in its many fields of application. Today's design finds itself at a critical moment where the conventional ‘modes’ of doing, thinking and application are increasingly challenged by the troubled ideology of globalisation, climate change, migration patterns and the rapid restructuring of locally driven manufacturing sectors. The volume presents a selection of papers on state-of-the-art design research work. As rapid technological development has been pushing and breaking new ground in society, the broad field of design is facing many unprecedented changes. In combination with the environmental, cultural, technological, and, crucially, pandemic transitions, design at large is called to fundamentally alter its modes of practice. Beyond the conventional models of conducting research, or developing solutions to ‘wicked’ problems, the recoupling of design with different modes should be seen as an expression to embrace other capacities of thinking, criticisms and productions. This selection of proceedings papers delivers the latest insights into design from a multitude of perspectives, as reflected in the eight thematic modes of the congress ; i.e., [social] , [making] , [business] , [critical], [historical/projective], [impact], [pandemic], and [alternative] with design modes. The book benefits design researchers from both academia and industry who are interested in the latest design research results, as well as in innovative design research methods. In presenting an interesting corpus of design case studies as well as studies of design impact, this comprehensive collection is of relevance to design theorists and students, as well as scholars in related fields seeking to understand how design plays a critical role in their respective domains.
