"Gems and Gemstones features nearly 300 color images of the cut gems, precious and semiprecious stones, gem-quality mineral specimens, and fine jewelry that are all part of the new Grainger Hall of Gems at The Field Museum. The book and exhibition explore 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 necklace. 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. And for anyone who has ever marveled at the innovations of top jewelry designers, Gems and Gemstones features an array of polished stones, gold objects, and creations from around the world."--Book jacket.
