Physical properties

Hardness of 5.5 to 7 on the Mohs scale, frosted or weathered surface texture, various translucent colors, amorphous crystal structure.

Created from discarded manufactured glass objects that have been weathered, tumbled, and smoothed by wave action in bodies of water over decades.

Used primarily for jewelry making, mosaic arts, decorative crafts, and as collector items.

Genuine sea glass requires 20 to 40 years of continuous tumbling in the ocean to achieve its characteristic frosted finish and smooth edges.

Found worldwide along the shores of oceans, seas, and large lakes, identifiable by its frosted, pitted texture and completely smooth, rounded edges.
