Book Description
The author of, "Faceting History: Cutting Diamonds and Colored Stones" has for a long time had a deep interest in learning how the early faceters (cutters) of diamonds and colored gemstones were able to complete their work. What methods did they use? What equipment did they have to make success possible? How soon did they discover how to complete the many phases necessary to accomplish their work? How did the equipment and methods differ between fashioning diamonds and faceting colored stones? These are just a few of the questions that the author wanted to find the answers for. In looking for answers to these and other questions, the author found that there were bits and pieces of information available in many previous books, but there was not a good book available that would answer most of his questions. Upon hearing the author's remarks about this fact, one of the librarians at the wonderful library located at the Gemological Institute of America's Carlsbad campus said that if such a book was not available, "maybe you should write the book!" Well, the author had been thinking of doing just that, but the remark caused the author to see the light and agree to get started on the project. Little did he know then that the project would require many months of eight hour days over seven day weeks to get the book completed. He decided to write a book that would answer these and other related questions that he had. The thought also occurred to him that such a book would be a valuable volume to be placed in libraries of individual faceters around the world. He realized that such a book would also be of great value to anyone who works behind a Jewelry store counter. A successful sales person isone who is knowledgeable about the products that they are selling. A book of faceting information would be extremely valuable if read and re-read from time to time. A customer in the Jewelry store will no doubt be favorably impressed by a sales presentation that is made with the use of interesting and informative information about diamonds and the various colored gemstones. The customer will be convinced that the sales person knows about what they are talking. The author has spent nearly three years on the project of researching the GIA library and other libraries, along with the extensive personal library of gemstone related books that he personally possesses. Many conflicting reports were noted in his study. He has made the statements in his book reflect the most commonly accepted opinions, of the most respected authors' works that he has found in his research. History is only obtainable from the earlier works of other authors. We cannot go back to the long past centuries ourselves, to see first hand what really happened and when it happened. A study of faceting history requires making the best choices of the information that is available. This completed book answers questions as to why the fashioning of diamonds was/is so different from the faceting of colored gemstones. The book compares the needed equipment and the methods that have brought the greatest successes. In addition, a great deal of other information connected to faceting is included. There are seven chapters in the book and there are over 125 photographs of the early equipment and methods that were used. The photographs show the faceters, the workroom conditions, and the tools and equipment that they used to completebeautiful and lasting gemstones. The book chapters are titled: An Introduction to Faceting, Early Man's Stone Appreciation, Diamond Fashioning Procedure and Equipment, Colored Stone Faceting Procedure and Equipment, The Evolution of Cut Designs, Famous and Historic Gemstones, Sources of Diamond and Colored Stone Rough, and lastly, Advances in Faceting Over the Past One Hundred Years. Within each of these chapters the reader will find a multitude of additional and interesting information. Chapter One: Early Faceting Inform

Book Description
George MacDonald (1824-1905) was writing at a time of Evangelical unease. In a society ravaged by Asiatic cholera, numbed by levels of infant mortality, and fearful of revolution and the toxicity of industry (to name but a few of the many challenges), the "gospel" proclaiming eternal damnation for unbelievers was hardly good news; rather, Christianity was increasingly viewed as the source of bad news and a tool of state oppression. MacDonald agreed: in his view, the church had become a vampire sucking the blood of her children instead of offering them eucharistic life. In contrast, like Christ, MacDonald brings before us a child. Although at first sight a familiar Romantic incarnation, in MacDonald's theology "the child" becomes an unlikely icon challenging the vampire's kingdom--a challenge reaching beyond the confines of Evangelicalism, confronting the foundations of much of Western theology. This meticulously-researched study exploring MacDonald's work--especially his "realist" and fantasy novels--in the light of its Victorian context is of more than historical interest. His incisive critique of church and empire have particular relevance today in light of the growing and troubling alliance between fundamentalist expressions of church and intolerant, right-wing politics. This volume considers MacDonald's radical solution to religious vampirism; becoming children.

Book Description
Why are sex and jewelry, particularly rings, so often connected? Why do rings continually appear in stories about marriage and adultery, love and betrayal, loss and recovery, identity and masquerade? What is the mythology that makes finger rings symbols of true (or, as the case may be, untrue) love? The cross-cultural distribution of the mythology of sexual rings is impressive--from ancient India and Greece through the Arab world to Shakespeare, Marie Antoinette, Wagner, nineteenth-century novels, Hollywood, and the De Beers advertising campaign that gave us the expression, "A Diamond is Forever." Each chapter of The Ring of Truth, like a charm on a charm bracelet, considers a different constellation of stories: stories about rings lost and found in fish; forgetful husbands and clever wives; treacherous royal necklaces; fake jewelry and real women; modern women's revolt against the hegemony of jewelry; and the clash between common sense and conventional narratives about rings. Herein lie signet rings, betrothal rings, and magic rings of invisibility or memory. The stories are linked by a common set of meanings, such as love symbolized by the circular and unbroken shape of the ring: infinite, constant, eternal--a meaning that the stories often prove tragically false. While most of the rings in the stories originally belonged to men, or were given to women by men, Wendy Doniger shows that it is the women who are important in these stories, as they are the ones who put the jewelry to work in the plots.

Book Description
From the author of Guns, Germs and Steel, Jared Diamond's Collapse: How Societies Choose to Fail or Survive is a visionary study of the mysterious downfall of past civilizations. Now in a revised edition with a new afterword, Jared Diamond's Collapse uncovers the secret behind why some societies flourish, while others founder - and what this means for our future. What happened to the people who made the forlorn long-abandoned statues of Easter Island? What happened to the architects of the crumbling Maya pyramids? Will we go the same way, our skyscrapers one day standing derelict and overgrown like the temples at Angkor Wat? Bringing together new evidence from a startling range of sources and piecing together the myriad influences, from climate to culture, that make societies self-destruct, Jared Diamond's Collapse also shows how - unlike our ancestors - we can benefit from our knowledge of the past and learn to be survivors. 'A grand sweep from a master storyteller of the human race' - Daily Mail 'Riveting, superb, terrifying' - Observer 'Gripping ... the book fulfils its huge ambition, and Diamond is the only man who could have written it' - Economis 'This book shines like all Diamond's work' - Sunday Times
