Quartz is a vast family of stones found across nearly every continent, known for its remarkable diversity of colors and forms despite a simple chemical makeup of SiO₂ (silicon dioxide). Forming in a trigonal crystal system, quartz typically grows as six-sided crystals with pointed terminations, though its shape can vary based on its geological origins.

Quartz’s colors are created by trace elements and mineral inclusions, giving rise to a broad spectrum of varieties. These include rock crystal, amethyst, citrine, smoky quartz, and tiger’s eye, as well as microcrystalline forms like jasper, carnelian, and agate. Additional structural and optical forms exist, each shaped by unique environmental conditions within Earth’s depths.
