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.
Diamonds in Nature: A Guide to Rough Diamonds illustrates the range of crystal shapes, colours, surface textures, and mineral inclusions of rough, uncut, naturally forming diamonds. Each chapter contains photographs that show the unique physical characteristics of the diamonds, and the accompanying text describes the processes that led to their formation. This book is an invaluable reference manual for professional geoscientists—including gemmologists and exploration geologists.
Excerpt from Diamond Design: A Study of the Reflection and Refraction and Refraction of Light in a Diamond This book is written principally for students of precious stones and jewellers, and more particularly, for' diamond manufacturers and diamond cutters and polishers. The author will follow the evolution of the shape given to a cut diamond, and discuss the values of the various shapes and the reason for' the discarding of the old shapes and the practically universal adoption of the brilliant.'

This is the first book devoted entirely to diamond inclusions in all its known natural characteristics. The first half of the book defines external and internal inclusions, describing each variety with numerous full color examples. What makes this work outstanding is the section in which inclusions are tracked from the rough to the cut and how the integrity of the diamond can be compromised by depth and position of the remaining inclusions. Additionally, an entire section is devoted to the diamond manufacturing process and its relationship to inclusions. In this area inclusions are examined with regards to heat, pressure, rotation, and other mechanical influences. Inclusions trapped in diamonds are full of information that in many cases is still to be scientifically interpreted. This book take us into the fascinating would of micro-inclusions giving us fresh insight in one of natureżs most sought after gems.
The paragon of physical perfection and a sparkling example of Earth's forces at work, the diamond has fascinated all realms of society, from Russian tsars and Hollywood stars to scientists and brides-to-be. The Nature of Diamonds is an authoritative and richly illustrated look at nature's most coveted gem. Leading geologists, gemologists, physicists, and cultural observers cover every facet of the stone, from its formation in the depths of the Earth and its explosive ascent to the surface, to its economic, regal, social, and technological roles. The book takes the reader to cutting-edge research on the frontiers of diamond exploration and exploitation, from Arctic wastes to laboratories that create industrial diamonds for cutting tools that slice through rock. Charting the history of mining from its origins in India and Brazil, the book follows the diamond rush in South Africa to today's high-tech enterprises. It provides a glimpse into the economics of the diamond trade, and an overview of diamond cutting, from the rough uncut stones in early Indian and Roman jewelry to the multifaceted stones we see today. The cultural history of the diamond as both a revered and a social symbol is explored, from its early history as the exclusive property of royalty to today's brilliant-laden jewelry as an emblem of wealth and status. The engaging text is complemented by more than 200 lavish illustrations which span fine art, earth science, and cultural studies and capture the brilliance and beauty of this extraordinary gem.
An American Library Association Notable Book When he proposed to his girlfriend, Tom Zoellner gave what is expected of every American man--a diamond engagement ring. But when the relationship broke apart, he was left with a used diamond that began to haunt him. His obsession carried him around the globe; from the "blood diamond" rings of Africa; to the sweltering polishing factories of India; to mines above the Arctic Circle; to illegal diggings in Brazil; to the London headquarters of De Beers, the secretive global colossus that has dominated the industry for more than a century and permanently carved the phrase "A diamond is forever" on the psyche. An adventure story in the tradition of Susan Orlean's The Orchid Thief, The Heartless Stone is a voyage into the cold heart of the world's most unyielding gem.
