A hobby backed by centuries of tradition, amateur gem cutting remains popular today. Once a completely unskilled beginner himself, Captain John Sinkankas never forgot his struggles in learning how to cut and polish gemstones without the benefit of an instructor. With his own experience in mind, he wrote Gem Cutting to make it possible for others to teach themselves how to do every type of lapidary work without having to attend classes. For over half a century, Gem Cutting has served as the go-to guide for beginners and experts alike. Offering a wealth of information for everyone, it starts with the fundamentals and leads logically to techniques and projects that will challenge even the most advanced cutter. Every step is described in detail and illustrated with drawings and photographs. Sinkankas covers common pitfalls and, wherever possible, offers hints on how to take money-saving shortcuts. Incorporating tips on operating equipment for greatest efficiency, he explains how to make or choose equipment for sawing, grinding, sanding, and other basic operations. Special chapters describe how to cut and polish cabochons, faceted gems, spheres and beads; how to tumble gems; and how to make carvings, engravings, inlays, and mosaics. Sinkankas also advises on selecting and buying rough gemstones. A section on the description and treatment of gemstones has been expanded in this second edition to include more species and accommodate recent information on each. With its comprehensive guidance, Gem Cutting is an essential addition to the library of any lapidary. Captain John Sinkankas (1915-2002) dedicated his life to the study of earth sciences after his retirement from the US Navy. Winner of the Desert Magazine Literature Premium Award, Sinkankas authored a number of books on gemstones and published over 100 articles on lapidary subjects. He was a certified gemologist of the American Gem Society with memberships to the Mineralogical Society of America, New York Mineralogical Club, San Diego Mineral & Gem Society, and several other regional gem and mineral groups.

They were America's longest lasting dynasty, the closest thing to a royal family our nation has ever known. The Adamses played a leading role in America's affairs for nearly two centuries -- from John, the self-taught lawyer who rose to the highest office in the government he helped to create; to John Quincy, the child prodigy who followed his father to the White House and fought slavery in Congress; to Charles Francis, the Civil War diplomat; to Henry, the brilliant scholar and journalist. Indeed, the history of the Adams family can be read as the history of America itself. For when the Adamses "looked at their past, they saw the nation's," writes author Richard Brookhiser. "When they looked at the nation's past, they saw themselves." America's First Dynasty charts the family's travels through American history along with an impressive cast of characters, among them George Washington, Thomas Jefferson, Ulysses S. Grant, and Theodore Roosevelt. Brookhiser also details the darker side of the Adams experience, from the specters of alcoholism and suicide to the crushing burden of performance passed on from father to son. Yet by putting a human face on this legendary family, Brookhiser succeeds in creating an impassioned, heroic family portrait that the American public is not likely to forget.
The place of religion in society has changed profoundly in the last few centuries, particularly in the West. In what will be a defining book for our time, Taylor takes up the question of what these changes mean, and what, precisely, happens when a society becomes one in which faith is only one human possibility among others.
