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.
The king of stones, valued since antiquity for their unrivalled hardness, diamonds today are both desired and deplored. Once faceted and polished they glitter on the fingers of brides-to-be and in the ornaments of the super-rich, but their extraction from some of the world’s poorest countries remains contentious. Immensely valuable for their size, diamonds can be easily hidden and transported, making them perfect contraband. Diamonds have been widely used in industry since the nineteenth century and have long been valued for their pharmaceutical and prophylactic properties. This entertaining and richly illustrated book examines the history of the diamond trade through the centuries from India and Brazil to South Africa and Europe and investigates what happens to diamonds once they reach the cutters and polishers. Marcia Pointon takes the reader on a unique tour of the ways in which the quadrahedron diamond shape has inspired design, architecture, and painting, from the symbolism of medieval manuscripts to modern-day graffiti. She questions the etiquette of engagement rings, and she reminds us why and how lost, stolen, or cursed diamonds create suspense in so many classic novels and films. This compelling and fascinating account of the history of sparklers around the world will appeal to all who covet, as well as all who despise, the unparalleled brilliance and glitter of the diamond.
Each gem deposit-whether of primary origin in the parent rocks; or secondary as alluvial placers in valley floors, river gravels, or the sand of oceanic shelves presents an eloquent chronicle of the Earth's life story. It reveals to the expert the prodigious processes which formed the present crust of our planet, of which this volume discloses a small but exciting detail. The materials of the Earth's crust are the rocks. In this book, the author expounds on how they were formed, why they altered, why they became the cradles of precious gemstones, how they are categorized, and how they are now exploited by man. What initiates the growth of gemstones? How do they crystallize? Why do gemstones of the same species, originating from different sources, vary? What causes the occurrence of varieties? Why do diamonds, unlike other precious stones, occur not near the Earth's surface in its crust, but deep down beneath it in the upper mantle? These are only a few of the entrancing subjects discussed in this enlightening volume. The reader learns that the Earth is surprisingly alive and altering constantly-sometimes through slow and equable changes and at times by violent and tremendous cataclysms, events from which gemstones issue.
