Quartz Groups

Quartz group crystals are among the most abundant and versatile minerals on Earth, known for their remarkable beauty, durability, and wide range of varieties. Composed primarily of silicon dioxide (SiO₂), quartz forms in a hexagonal crystal system and exhibits a vitreous luster with a transparency that ranges from transparent to opaque. Quartz crystals are admired for their six-sided prismatic shapes, often terminated with pyramidal points.
