Book Description
From the dawn of time, ruby and sapphire have both attracted and fascinated humans in ways that few other items could.While objects of desire are found throughout the natural world, physical beauty is too often ephemeral. From the allure of a man, woman, flower or butterfly, through the fleeting moments of a sunset, there is little that lasts and practically nothing that can be passed down to our descendants. The exception is precious stones. Not only are they the most durable creations of mother nature, but their visual splendor is truly eternal.In this companion to his 2013 book, Ruby & Sapphire--A Collector's Guide, Richard Hughes examines these gems from the gemological standpoint, delving into these gems not just from the aesthetic, but also from the scientific point of view.The product of nearly 40 years of firsthand experience, it covers every aspect of the subject from A-Z. History, sources, prices, quality analysis, synthetics and treatments, everything is here. Ruby & Sapphire--A Gemologist's Guide represents the most comprehensive book ever written on a single precious stone. With over 1000 photos, maps and illustrations and 3500 references, it is nothing less than a tour-de-force of gemological scholarship.

Book Description
This book takes the reader into some of the most intransigent social, economic, and political issues that impact achieving sustainable development in Asia and the Pacific. Through meticulous analysis of the integrated relationships between population, development, and the environment, the chapters in this volume investigate the impacts of hydropower development on fragile ecosystems; mining, landslides and environmental degradation; deforestation; water and food security; rural-urban migration, poverty alleviation, civil society and community empowerment; and how disaster recovery requires multi-scalar and multi-disciplinary approaches that take into account governance, culture, and leadership. Legal frameworks may be legislated, but are often rarely implemented. The book will be valuable to students of sustainability, population and development, and governmental policy advising sectors as well as the NGO and humanitarian sectors. The distinctive characteristic of this book is that it encapsulates an integrated, multi-disciplinary focus which brings to the discussion both robust empirical research and challenging policy applications in the investigation of how the sustainable development goals may be achieved in Asia and the Pacific.
