Physical properties

Hardness: 6-7 (mostly quartz-based); Color: vary from purple, pink, white, green, and metallic gold; Luster: Vitreous to metallic; Crystal Structure: Hexagonal and Cubic

Formation & geological history

Formed through hydrothermal processes, igneous cooling in pegmatites, and secondary mineral growth in volcanic cavities (geodes).

Uses & applications

Ornamental use, gemstone collecting, metaphysical jewelry, and industrial oscillators for quartz components.

Geological facts

This collection includes Amethyst (colored by iron and radiation), Rose Quartz (colored by titanium/manganese), and Pyrite (fools gold).

Field identification & locations

Identify by testing hardness (quartz will scratch glass) and observing crystal habit (6-sided prisms for quartz). Commonly found in riverbeds, mines, and volcanic regions.
