Physical properties
Varied: Hardness 3-7 (Mohs); colors include purple (amethyst), white (quartz/calcite), gold (pyrite), and red (jasper); lustors range from vitreous to dull; crystal habits include hexagonal prisms and rhombohedrons.
Formation & geological history
Diverse geological origins including hydrothermal veins, sedimentary deposits (fossils), and metamorphic formations across various eras from the Paleozoic to the Cenozoic.
Uses & applications
Educational purposes, crystal healing, decor, and starter kits for mineral collecting.
Geological facts
This collection contains several distinct types of specimens including a large quartz cluster, polished tiger's eye, amethyst druze, pyrite (fool's gold), and small fossils like crinoid stems.
Field identification & locations
Identify by testing hardness (quartz scratches glass) and acid reaction (calcite fizzes). Common in gift shops and rockhound starter kits worldwide.
