Physical properties
Hardness: 2–7 (Mohs scale), Color: Variegated (purples, greens, blues, whites), Luster: Vitreous to pearly, Crystal structure: Various (Hexagonal, Monoclinic, Cubic)
Formation & geological history
Formed through hydrothermal processes, sedimentary deposition, and volcanic activity over millions of years across various geological environments.
Uses & applications
Educational sets, metaphysical tools, jewelry making, and beginner mineral collecting.
Geological facts
The collection includes Amethyst (the purple variety of quartz), Selenite (the fibrous variety of gypsum), and likely Sodalite and Turquoise-colored stones.
Field identification & locations
Identify by testing hardness; Selenite can be scratched by a fingernail whereas Quartz/Amethyst cannot. Commonly sold in 'treasure' bags at museum gift shops or gem mines.
