Formation & geological history
Formed in cavities of volcanic rocks or limestone via deposition from silica-rich groundwater. Often associated with the Cretaceous period in northern Mexico.
Uses & applications
Widely used as an ornamental stone, fashioned into cabochons for jewelry (as seen in the ring), and polished for collectors.
Geological facts
Often called the 'Laughter Stone' or 'Happy Lace' in metaphysical circles. The most famous deposits are in Chihuahua, Mexico.
