Physical properties
Hardness 6-7 on the Mohs scale, tan to yellowish-brown color, dull luster, granular crystal structure, and porous texture.
Formation & geological history
Formed from the accumulation, compaction, and cementation of quartz sand grains over millions of years.
Uses & applications
Primarily used as a decorative collector's item or novelty due to its natural heart shape.
Geological facts
Naturally shaped by differential weathering and erosion, where softer mineral veins erode faster than the resilient quartz core.
Field identification & locations
Found commonly in sedimentary rock formations, riverbeds, and coastlines. Collectors value naturally weathered heart-shaped stones as unique keepsakes.
