Physical properties
Hardness: 6.5-7 on the Mohs scale, Color: complex banding in white, gray, cream, brown, and sometimes red or pink, Luster: Waxy to vitreous, Crystal structure: Cryptocrystalline, Cleavage: None (conchoidal fracture), Specific gravity: 2.58-2.64
Formation & geological history
Formed in cavities within volcanic rocks or ancient lavas. Silica-rich waters percolate through the rock, depositing layers of chalcedony over millions of years. Often found in Mexico.
Uses & applications
Commonly used in lapidary arts for cabochons, beads, carvings, and polished display pieces due to its intricate patterns.
Geological facts
Known as the 'Laughter Stone' or 'Happy Lace' in metaphysical circles. It is almost exclusively found in the state of Chihuahua, Mexico.
Field identification & locations
Identified by its chaotic, swirling, lace-like banding patterns. Found primarily in Mexico. Collectors seek pieces with tight, complex patterns and distinct color contrast.
