White Sea Glass
Silicate glass (anthropogenic, tumbled) · Decorative Stone / Ornamental Material
Crystal System
Amorphous (Non-crystalline)
Mineral Group
Man-made vitreous material
Chemical Formula
SiO2 with various fluxes and stabilizers (Na2O, CaO)
Formation Process
Anthropogenic production followed by natural marine weathering, mechanical abrasion, and tumbling by wave action over decades
About This Crystal
An opaque, matte-textured, frosted white piece of sea glass, irregularly shaped with smoothed, water-worn edges, securely wrapped in copper wire as a necklace pendant
Physical Characteristics
White to off-white body color, white streak, amorphous habit, no cleavage, conchoidal fracture smoothed by tumbling, specific gravity approximately 2.4 to 2.8, brittle tenacity, inert to magnetism and piezoelectricity
Optical Properties
Isotropic, singly refractive, opaque to translucent depending on thickness, dull or frosted vitreous luster, no pleochroism or special optical phenomena
Hardness & Durability
Origin Region
Found globally along ocean shores, sea coasts, and large freshwater lakes
Hardness & Durability
Mohs hardness around 5.5 to 6, moderate durability, stable under normal environmental conditions, suitable for casual jewelry if securely set
Care & Maintenance
Wash with warm soapy water and a soft cloth, store separately to avoid scratching softer materials, avoid harsh acids and abrasive cleaners
Rarity & Value
Common, though specific frosted shapes and colors vary; low monetary value, prized primarily for hand-crafted artisan jewelry and beachcombing collections
Special Characteristics
Frosted, etched surface texture created by natural sand-blasting and water-action over long periods in a marine environment
Lore & History
Often associated with themes of renewal, healing, transformation, and connection to water elements in modern crystal and beach lore, though these are symbolic beliefs rather than scientific properties
