Physical properties
Hardness of 7 on the Mohs scale, colorless to white, vitreous luster, hexagonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Formed when mineral-rich hydrothermal fluids precipitate silica within gas cavities in volcanic or sedimentary rocks over millions of years.
Uses & applications
Widely used in jewelry, ornamental decor, metaphysical practices, and industrial electronics.
Geological facts
Geodes appear as ordinary rocks on the outside but conceal stunning crystal formations within their hollow interiors when cracked open.
Field identification & locations
Easily identified by its high hardness, inability to be scratched by steel, and crystalline druzy interior. Found globally, especially in Brazil, Mexico, and the USA.
