Book Description
Among rock-forming minerals, the colorful tourmaline group is a favorite of both mineral collectors and gemologists. Superb examples are found at many locales worldwide, and in diverse geological settings from pegmatites to schists. Over 120 clear, crisp photos show each mineral in its geological context. This book will help mineral and gem collectors understand tourmaline mineralogy and see how changes in nomenclature reflect our evolving understanding of the group. The text explains the chemistry and taxonomy of the group, the environment in which tourmalines form, provides a detailed entry for each mineral including locality information and full-color photos wherever possible so that collectors can see what good specimens look like and which minerals one might expect to find in association with them. An extensive bibliography is provided for readers who wish to learn more. Every serious mineralogist, gemologist, and rock hound will need this book.

Book Description
A renowned jewelry expert recounts her career working with nature’s most extraordinary treasures—gemstones—and traces these rare jewels from ancient Egyptian records through the high-stakes auctions of today. Helen Molesworth has been captivated by precious stones since early childhood but she struggled to join the gemstone industry, having no connections to the few family-run companies that have dominated the field for centuries. She persevered, and more than two decades later, Molesworth is now an international authority hired to appraise the extraordinary jewelry of such clients as the British royal family. Precious is packed with inside stories about fabulous jewels associated with generations of celebrities, from Cleopatra (emerald) to Catherine, Princess of Wales (sapphire); from Marilyn Monroe (pearl) to Beyoncé (garnet); from Jackie O (pearl) to Lady Gaga (diamond); and from Marie Antoinette (pearl) to Elizabeth Taylor (pearl, ruby, and emerald)! As Molesworth tells it, the history of gemstones is the history of humanity. And so she journeys the world, navigating African diamond mines, Colombian emerald mines, and the sapphire-rich rivers of Sri Lanka to study gems at their source. She has selected ten of nature’s most dazzling gems, tracing their discovery to when these cut-and-polished masterpieces first adorned empresses and kings. From the stories of a priceless emerald watch hidden under floorboards for centuries to the common quartz fashioned into world-famous royal jewels, and diamonds selling for multi-millions, Precious is not just a chronicle of archeology and geology, high society and high finance, it’s the story of our timeless ambition to make—and wear—something beautiful.
