The concept of crystals dates back to ancient Greece, where the term *krystallos*—meaning ice—was used to describe clear, transparent stones like quartz. Early civilizations prized crystals for their beauty and perceived mystical properties, incorporating them into jewelry, amulets, and royal regalia. This reverence laid the groundwork for later scientific inquiry into their atomic structures.
By the 19th century, scientists such as Auguste Bravais and William Hallowes Miller systematically classified crystal structures, revealing the periodic arrangement of atoms. This period marked a shift from symbolic to scientific understanding, enabling advancements in materials science that would later influence industries from electronics to cosmetics.
