CHARACTERISTICS
Chemical Composition: Quartz is composed of silicon dioxide (SiO₂).
Color: Pure quartz, known as rock crystal, is colorless and transparent. However, impurities can give quartz a wide range of colors, resulting in varieties such as amethyst (purple), citrine (yellow), rose quartz (pink), and smoky quartz (brown).
Hardness: Quartz ranks 7 on the Mohs scale, making it a durable mineral suitable for various applications.
Crystal Structure: Quartz has a hexagonal crystal system and typically forms six-sided prisms ending in six-sided pyramids.
Transparency: Quartz can be transparent to opaque, with the level of transparency affecting its value and use.
HISTORY AND LORE
