Physical properties
Mohs hardness of 7, white to translucent color, vitreous luster, cryptocrystalline or microcrystalline structure, conchoidal fracture, and specific gravity around 2.65.
Formation & geological history
Formed via prolonged water tumbling and natural weathering of quartz-rich rocks in riverbeds or marine environments over millions of years.
Uses & applications
Used as a decorative keepsake, novelty specimen for collectors, and in lapidary displays.
Geological facts
Naturally occurring heart-shaped stones are exceptionally rare geological curiosities formed by selective erosion and differential weathering.
Field identification & locations
Identified by its high hardness, absence of effervescence with acid, and distinctive natural heart shape found along beaches and streams.
