Physical properties
Hardness 7 on Mohs scale, vitreous luster, conchoidal fracture, lacks cleavage. White to clear base with reddish-brown to orange staining.
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments. The iron staining occurs when iron-bearing fluids penetrate fractures or coat the surface, often during weathering.
Uses & applications
Tumbled stones for collection, landscaping, occasionally used in low-end jewelry or crafts.
Geological facts
Quartz is one of the most abundant minerals on Earth's crust. The red coloring is often referred to as 'hematoid' quartz if the inclusions are primarily hematite.
Field identification & locations
Can be identified by its hardness (scratches glass) and conchoidal fracture. Common in riverbeds, beaches, and gravel deposits worldwide. Good for tumbling.
