Alexandrite Origins

The book also explains the physics behind alexandrite's pleochroism, the phenomenon that causes it to appear green in daylight and red in incandescent light. This color change is due to the way chromium ions absorb light within the crystal structure. Furthermore, it examines the historical and economic significance of alexandrite discoveries, noting how its rarity contributes to its value.

The book progresses from introducing chrysoberyl's composition to exploring geological environments and metamorphic events to discussing pleochroism and historical discoveries. This book uniquely emphasizes the geological rarity and specific formation conditions of alexandrite.

By presenting complex scientific information in an accessible manner, Alexandrite Origins caters to a broad audience, including geology students, gemologists, and anyone interested in Earth sciences and the origins of gemstones.
