Physical properties
Hardness varies 1-7 (Mohs), diverse colors (red jasper, green aventurine, etc.), luster ranges from vitreous to dull, various crystal systems.
Formation & geological history
Global origin; includes igneous (Obsidian, Granite), sedimentary (Sandstone, Coal), and metamorphic (Marble, Gneiss) specimens formed over millions of years.
Uses & applications
Educational sets for earth science learning, rock hounding starters, and decorative lapidary collecting.
Geological facts
This set contains common representative samples like Pyrite (Fool's gold) and Snowflake Obsidian (volcanic glass with cristobalite inclusions).
Field identification & locations
Identifiable by labeled grid; used to teach the rock cycle and mineral identification techniques like streak tests and hardness comparisons.
