Sapphire Growth explores the geological environments and processes that transform the mineral corundum into stunning sapphires, gems coveted worldwide. It delves into the crucial role of trace elements like iron and titanium, revealing how their presence and concentration dictate a sapphire’s color, from deep blues to vibrant pinks and yellows. The book highlights that even slight variations in chemical composition can dramatically alter a gemstone’s appearance.
The book systematically unfolds the story of sapphire formation, starting with corundum’s basic properties and advancing to the geological settings that foster crystal growth. Different deposit types, such as magmatic, metamorphic, and alluvial, are examined to understand their unique influence on sapphire characteristics. Case studies from major sapphire-producing regions like Sri Lanka and Madagascar illustrate the varied geological histories that contribute to gem genesis, using geological maps and spectroscopic data to support its findings.
Targeted toward students, geologists, and gem enthusiasts, Sapphire Growth presents a fact-based, accessible overview of sapphire genesis, emphasizing natural processes and geological factors. By integrating mineralogy, geochemistry, and petrology, the book offers a holistic understanding of sapphire formation, providing valuable insights into exploration strategies and gemstone provenance.
