Paperback. Condizione: new. Paperback. What is a gemstone?At first glance, it appears to be simply a beautiful stone-clear, colorful, and shining. Yet beneath its surface lies a long history.Gemstones form deep within the Earth under conditions of pressure, heat, and time. Over millions of years, their crystals grow within rocks, hidden far below the surface until geological processes eventually bring them into view.This book explores gemstones from a scientific perspective. It explains how crystals form, why gemstones display their colors, how light is refracted within them, and which geological processes make their formation possible.In doing so, it becomes clear that gemstones are more than decorative objects. They are small archives of the Earth-mineral structures that preserve clues about the history of our planet.The Science of Gemstones combines natural science with a quiet reflection on the processes that transform simple elements into some of the most fascinating structures found in nature.
