Physical properties
Hardness: 5.5 to 7 on the Mohs scale, Color: various frosted shades of green, brown, or clear, Luster: vitreous when wet, frosted or matte when dry, Crystal structure: amorphous solid
Formation & geological history
Formed from discarded man-made glass objects that have been weathered, tumbled, and smoothed by wave action, sand, and saltwater over decades in marine environments
Uses & applications
Collected for crafting, jewelry making, and beachcombing displays
Geological facts
Genuine sea glass takes anywhere from 20 to over 40 years of continuous tumbling in the ocean to achieve its characteristic frosted surface texture and rounded edges
Field identification & locations
Found along the shores of oceans, large lakes, and rivers worldwide, particularly near historic shipping lanes or populated coastal areas; easily identified by its smooth, frosted appearance and lack of sharp edges
