Physical properties
Hardness: 6-7 (Mohs scale); Color: Tan/Beige with black and pink ink; Luster: Dull/Earthy; Texture: Smooth, water-worn/rounded clastic texture.
Formation & geological history
Formed through the accumulation of sand grains in high-energy aquatic environments (rivers or beaches), followed by lithification. This specific specimen has undergone secondary human-induced artistic modification.
Uses & applications
Primarily used as a decorative novelty item, paperweight, or childhood craft project.
Geological facts
The 'Pet Rock' was a marketing craze in the mid-1970s created by Gary Dahl; this specimen continues that tradition of personifying geological materials.
Field identification & locations
Identify in the field by its distinct smiley face and unusual facial features not typically found in nature. Found commonly in suburban households and craft bins.
