Download or read book Faceting History Cutting Diamonds and Colored Stones written by Glenn Klein and published by Xlibris Corporation. This book was released on 2005 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

This book was released on 2021-02-23 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Unforgettable. . . . An outstanding adventure in its lyrical, utterly compelling, and heartbreaking investigations of the world of diamond smuggling.” —Aimee Nezhukumatathil For nearly eighty years, a huge portion of coastal South Africa was closed off to the public. With many of its pits now deemed “overmined” and abandoned, American journalist Matthew Gavin Frank sets out across the infamous Diamond Coast to investigate an illicit trade that supplies a global market. Immediately, he became intrigued by the ingenious methods used in facilitating smuggling particularly, the illegal act of sneaking carrier pigeons onto mine property, affixing diamonds to their feet, and sending them into the air. Entering Die Sperrgebiet (“The Forbidden Zone”) is like entering an eerie ghost town, but Frank is surprised by the number of people willing—even eager—to talk with him. Soon he meets Msizi, a young diamond digger, and his pigeon, Bartholomew, who helps him steal diamonds. It’s a deadly game: pigeons are shot on sight by mine security, and Msizi knows of smugglers who have disappeared because of their crimes. For this, Msizi blames “Mr. Lester,” an evil tall-tale figure of mythic proportions. From the mining towns of Alexander Bay and Port Nolloth, through the “halfway” desert, to Kleinzee’s shores littered with shipwrecks, Frank investigates a long overlooked story. Weaving interviews with local diamond miners who raise pigeons in secret with harrowing anecdotes from former heads of security, environmental managers, and vigilante pigeon hunters, Frank reveals how these feathered bandits became outlaws in every mining town. Interwoven throughout this obsessive quest are epic legends in which pigeons and diamonds intersect, such as that of Krishna’s famed diamond Koh-i-Noor, the Mountain of Light, and that of the Cherokee serpent Uktena. In these strange connections, where truth forever tangles with the lore of centuries past, Frank is able to contextualize the personal grief that sent him, with his wife Louisa in the passenger seat, on this enlightening journey across parched lands. Blending elements of reportage, memoir, and incantation, Flight of the Diamond Smugglers is a rare and remarkable portrait of exploitation and greed in one of the most dangerous areas of coastal South Africa. With his sovereign prose and insatiable curiosity, Matthew Gavin Frank “reminds us that the world is a place of wonder if only we look” (Toby Muse).
Download or read book Polishing of Diamond Materials written by Yiqing Chen and published by Springer Science & Business Media. This book was released on 2013-02-13 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diamond has a unique combination of properties, such as the highest hardness and thermal conductivity among any known material, high electrical resistivity, a large optical band gap and a high transmission, good resistance to chemical erosion, low adhesion and friction, and extremely low thermal expansion coefficient. As such, diamond has been a desirable material in a wide range of applications in mechanical, chemical, optical, thermal and electrical engineering. In many of the cases, the surface of a diamond component or element must have a superior finish, often down to a surface roughness of nanometers. Nevertheless, due to its extreme hardness and chemical inertness, the polishing of diamond and its composites has been a sophisticated process. Polishing of Diamond Materials will provide a state-of-the-art analysis, both theoretically and experimentally, of the most commonly used polishing techniques for mono/poly-crystalline diamond and chemical vapour deposition (CVD) diamond films, including mechanical, chemo-mechanical, thermo-chemical, high energy beam, dynamic friction and other polishing techniques. The in-depth discussions will be on the polishing mechanisms, possible modelling, material removal rate and the quality control of these techniques. A comparison of their advantages and drawbacks will be carried out to provide the reader with a useful guideline for the selection and implementation of these polishing techniques. Polishing of Diamond Materials will be of interest to researchers and engineers in hard materials and precision manufacturing, industry diamond suppliers, diamond jewellery suppliers and postgraduate students in the area of precision manufacturing.
