Physical properties
Hardness varies from 6 to 7 on the Mohs scale depending on quartz content. Displays a smooth, weathered surface with earthy brown tones and a dull to sub-vitreous luster.
Formation & geological history
Formed through the accumulation and cementation of mineral particles over millions of years, subsequently shaped by water erosion in a river environment.
Uses & applications
Used primarily as decorative items, garden stones, keepsakes, and collector specimens due to its natural heart shape.
Geological facts
Naturally occurring heart-shaped stones are formed by differential weathering where softer minerals erode faster than harder quartz veins.
Field identification & locations
Found commonly in riverbeds and beaches worldwide; identified by its smooth, water-worn contours and naturally symmetrical shape.
