Quartz

he term “quartz” derives from the German word “Quarz,” which has roots in the Slavic “tvrdý,” meaning “hard.” The ancient Greeks referred to clear quartz as “krustallos,” meaning “ice,” believing it to be eternally frozen water. Quartz has numerous alternate names based on its varieties, including amethyst, citrine, rose quartz, smoky quartz, and rock crystal.

Composition and Physical Characteristics

Quartz is a silicon dioxide (SiO₂) mineral, crystallising in the trigonal system. It possesses a Mohs hardness of 7, exhibiting remarkable durability. Its fracture is conchoidal, and it presents a vitreous to greasy lustre. Pure quartz is transparent, but trace elements, inclusions, or irradiation can yield a spectrum of colours and patterns. Some varieties exhibit chatoyancy, asterism, or phosphorescence.

Quartz manifests in numerous forms, including:

• Macrocrystalline Quartz (large visible crystals): Rock crystal, amethyst, citrine, smoky quartz, rose quartz, blue quartz.
• Cryptocrystalline Quartz (microcrystalline structure): Chalcedony, agate, carnelian, onyx, jasper, and aventurine.
• Synthetic Quartz: Lab-grown specimens used in industrial applications and jewellery.
