Physical properties
Hardness: 7 (Mohs); Color: Transparent to white crystals on brown/gray matrix; Luster: Vitreous/sparkly; Crystal system: Hexagonal/Trigonal; Texture: Granular to crystalline surface.
Formation & geological history
Formed when silica-rich water cools or evaporates within rock cavities or fractures, often in volcanic or sedimentary environments. These druzy coatings can take millions of years to grow.
Uses & applications
Primarily collected for aesthetic value, used in jewelry (as pendants or beads), and used in metaphysical practices as a grounding stone.
Geological facts
The term 'druzy' (or drusy) refers to the tiny glittering crystals that form on the surface of a larger rock mineral. These crystals act like a natural glitter, catching light from every angle.
Field identification & locations
Identify in the field by looking for a 'sugary' coating that sparkles in the sun. Common in geode-rich areas like the Midwest US, Brazil, or Morocco. Use a magnifying lens to see individual crystal faces.
