Physical properties
Likely a natural, colorless quartz crystal with reflective faces and internal fractures; Mohs hardness 7, vitreous luster, hexagonal crystal system, and no true cleavage. The image alone cannot confirm the identification or distinguish natural from treated material.
Formation & geological history
Quartz crystallizes from silica-rich fluids in veins, cavities, and pegmatites; it occurs in rocks of many ages and geological settings.
Uses & applications
Used for collecting, jewelry, ornament, and industrial applications such as glassmaking and electronics.
Geological facts
Quartz is among Earth’s most abundant minerals; internal fractures can produce bright rainbow-like reflections.
Field identification & locations
Look for glassy luster, hardness sufficient to scratch glass, and lack of cleavage; common worldwide in veins and geodes. Comparable clear quartz specimens typically sell for about $5–$50, depending on size, clarity, and crystal quality.
