Gems are objects of wealth, icons of beauty, and emblems of the very best of everything. They are kept as signs of prestige or power. Given as tokens of love and affection, they also come in a kaleidoscopic array of hues and can be either mineral or organic. Gems can command a person’s gaze in the way they play with light and express rich color. And they can evoke feelings of passion, greed, mystery, and warmth.
For millennia, gems have played an important role in human culture: they have significant value, both financially and within folklore and mythology. But just what are gems, exactly? This lavishly illustrated volume—the most ambitious publication of its kind—provides a general introduction to gems and natural gemstones, conveying their timeless beauty and exploring similarities among different species and varieties. Gems and Gemstones features nearly 300 color images of the cut gems, precious and semiprecious stones, gem-quality mineral specimens, and fine jewelry to be unveiled in a new Grainger Hall of Gems at The Field Museum in Chicago this October. The book and exhibition’s overarching theme will be the relationship between finished gems and their natural origin: while beautiful as faceted and polished pieces of jewelry, gems are often just as lovely—or even more so—as gemstones in their natural state. For example, an aquamarine or emerald as originally found in a mine with its natural crystal faces can be as stunning as any cut and polished gem prepared for a ring, bracelet, or charm.
Thoughtful of both ancient and modern times, Gems and Gemstones also includes fun-filled facts and anecdotes that broaden the historical portrait of each specimen. When Harry Winston, for instance, donated the Hope Diamond to the Smithsonian in 1958, he sent it through the U.S. mail wrapped in plain brown paper. And for anyone who has ever marveled at the innovations of top jewelry designers, Gems and Gemstones features a dazzling array of polished stones, gold objects, and creations from around the world. Diamonds, sapphires, rubies, amethysts, pearls, topaz, amber—every major gem gets its due in what will be an invaluable source on the subject for years to come.
Gems and Gemstones is the basis for the iPad app, available in the Apple iTunes App Store, Gems and Jewels.
In 1925 the geological connection between Flint Ridge and Mammoth Cave was proved when dye placed in a Flint Ridge spring showed up in Echo River at Mammoth Cave.
That tantalizing swirl of dye confirmed speculations that wereto tempt more than 650cavers over half a century with the thrill of being the first to make human passage of the cave connection. Roger Brucker and Richard Watson tell not only of their own twenty-year effort to complete the link but the stories of many others who worked their way through mud-choked crawlways less than a foot high only to find impenetrable blockages.
Floyd Collins died a grisly death in nearby Sand Cave in1925, after being trapped there for 15 days. The wide press coverage of the rescue efforts stirred the imagination of the public and his body was on macabre display in a glass-topped coffin in Crystal Cave into the 1940s. Agents of a rival cave owner once even stole his corpse, which was recovered and still is in a coffin in the cave. Modern cavers still have a word with Floyd as they start their downward treks.
Brucker and Watson joined the parade of cavers who propelled themselves by wiggling kneecaps, elbows, and toes through quarter-mile long crawlways, clinging by fingertips and boot toes across mud-slick walls, over bottomless pits, into gurgling streams beneath stone ceilings that descend to water level, down crumbling crevices and up mountainous rockfalls, into wondrous domed halls, and straight ahead into a blackness intensified rather than dispelled by the carbide lamps on their helmets.
Over two decades they explored the passages with others who sought the final connection as vigorously as themselves. Pat Crowther, a young mother of two, joined them and because of her thinness became the member of the crew to go first into places no human had ever gone before. In that role, in July 1972, she wiggled her way through the Tight Spot and found the route that would link the Flint Ridge and Mammoth Cave systems into one cave extending 144.4 miles through the Kentucky limestone.
In a new afterword to this edition the authors summarize the subsequent explorations that have more than doubled the established length of the cave system. Based upon geological evidence, the authors predict that new discoveries will add another 200 miles to the length of the world’s longest cave, making it over 500 miles long.
Join the conversation as an earth scientist and a Native American elder—wise men from two cultures—explore the natural history of the Lake Superior region, examining both the science and the spirit of the land.
As the geologist carefully presents a modern scientific perspective, the storyteller eloquently recounts a traditional Native American understanding, passed on through tales, myths, and symbols that illustrate how intimately his people have known and honored the earth and its history for over a hundred centuries.
Talking Rocks is not only a story of geological history told from two perspectives, it is also a chronicle of two people from very different cultural and scientific heritages learning to understand and appreciate each other’s distinct yet complementary ways of viewing the land we share.
