Physical properties
Hardness: 7 on Mohs scale; Color: Clear to white with reddish-brown streaks; Luster: Vitreous; Crystal system: Hexagonal (trigonal); Cleavage: None/Conchoidal fracture; Specific gravity: 2.65.
Formation & geological history
Formed in hydrothermal veins and pegmatites. The red coloration is due to the presence of hematite (iron oxide) inclusions that were trapped during the crystal growth process.
Uses & applications
Used primarily by collectors and in metaphysical jewelry (often called 'Fire Quartz' or 'Hematoid Quartz'). High-purity quartz is also used in electronics and glass-making.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust. Specimens like this one, showing internal iron staining, are often found in areas with high oxidizing iron content.
Field identification & locations
Identify by its ability to scratch glass, its lack of cleavage, and the characteristic rusty-red internal staining. It is commonly found worldwide, particularly in Brazil, Madagascar, and the USA.
