Gemstones: Mineralogy and Geochemistry

Gemstones refer to pieces of mineral crystals that have been cut and polished, and are used for creating jewelry and other adornments. They come in a wide variety of colors and shades. Mineralogy refers to the study of the chemistry, crystal structure and physical properties of minerals and mineralized artifacts such as gemstones. Geochemistry refers to the study of the chemical composition of the Earth and its rocks and minerals. As gemstones are formed and found beneath the Earth's surface and may contain traces of minerals, they are studied under the subjects of mineralogy and geochemistry. They can be categorized as crystalline or amorphous. Minerals with a definite and regular internal atomic structure are called crystalline gemstones. Amorphous gemstones have no naturally occurring form and no organized internal atomic structure. This book includes some of the vital pieces of works being conducted across the world, on various topics related to the mineralogy and geochemistry of gemstones. With its detailed analyses and data, it will prove immensely beneficial to professionals and students involved in this area of study at various levels.
