Book Description
The Periodic Table: Nature’s Building Blocks: An Introduction to the Naturally Occurring Elements, Their Origins and Their Uses addresses how minerals and their elements are used, where the elements come from in nature, and their applications in modern society. The book is structured in a logical way using the periodic table as its outline. It begins with an introduction of the history of the periodic table and a short introduction to mineralogy. Element sections contain their history, how they were discovered, and a description of the minerals that contain the element. Sections conclude with our current use of each element. Abundant color photos of some of the most characteristic minerals containing the element accompany the discussion. Ideal for students and researchers working in inorganic chemistry, minerology and geology, this book provides the foundational knowledge needed for successful study and work in this exciting area. Describes the link between geology, minerals and chemistry to show how chemistry relies on elements from nature Emphasizes the connection between geology, mineralogy and daily life, showing how minerals contribute to the things we use and in our modern economy Contains abundant color photos of each mineral that bring the periodic table to life

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
Most of the material presented here was originally published in Gems & Gemology as articles and lab notes (short reports from the GIA Laboratory, formerly called the Gem Trade Laboratory) or as Gem News/Gem News International items between the years 1938 and 2007. Also included are summaries of presentations at GIA's 2006 International Gemological Symposium and Gemological Research Conference, which originally appeared in the Fall 2006 Proceedings volume produced by Gems & Gemology staff. The present work is organized in two main parts on color treatments and clarity treatments, with color photos and microimages on almost every page. Chapters in the section on color treatments cover coated diamonds, irradiated diamonds, and annealed diamonds. Chapters in the section on clarity treatments cover laser-drilled and glass-filled diamonds. Material is presented in chronological order to help readers follow the evolving areas of interest and understanding of these treatments. Some of the older material includes editorial comments to explain now-unfamiliar concepts or discuss significant development since the original publication. The book includes a poster-sized color chart enclosed in a side pocket, with color photos demonstrating diagnostic features of filled diamonds and testing techniques. Shigley is a distinguished research fellow at the GIA Lab in Carlsbad, California.

Book Description
1.1 Prologue What is archaeomineralogy? The term has been used at least once before (Mitchell 1985), but this volume is the first publication to lay down the scientific basis and systematics for this subdiscipline. Students sometimes call an introductory archaeology course "stones and bones." Archaeomineralogy covers the stones component of this phrase. Of course, archaeology consists of a great deal more than just stones and bones. Contemporary archaeology is based on stratigraphy, geomorphology, chronometry, behavioral inferences, and a host of additional disciplines in addition to those devoted to stones and bones. To hazard a definition: archaeomineralogy is the study of the minerals and rocks used by ancient societies over space and time, as implements, orna ments, building materials, and raw materials for ceramics and other processed products. Archaeomineralogy also attempts to date, source, or otherwise char acterize an artifact or feature, or to interpret past depositional alteration of archaeological contexts. Unlike geoarchaeology, archaeomineralogy is not, and is not likely to become, a recognized subdiscipline. Practitioners of archaeomineralogy are mostly geoarchaeologists who specialize in geology and have a strong background in mineralogy or petrology (the study of the origin ofrocks).

Above all, they tell the human stories that underpin the adoration of diamonds. Diamonds Across Time is a richly illustrated publication with high-quality images of gems and jewels, archival documents, rare drawings, and fabulous photographs. The volume places diamonds in the context of the time in which they were discovered, and on the political, social, and cultural stage on which their histories were etched. In a rapidly changing world, diamonds are eternal. They were created by nature and grew in the womb of the earth. They tell stories, and they record history. With this book, diamonds will finally have their own storytellers. The book was compiled and edited by the World Diamond Museum's chief curator and world-renowned jewelry expert Dr. Usha R Balakrishnan. She and nine other distinguished authors wrote ten monographs written in the order in appearance: Introduction; The Nizam Diamond: Bala Koh-i-Noor, in the Sacred Trust of the Nizam of Hyderabad - Usha R.
