Moss Agate Necklaces in Sterling Silver  

Natural Moss Agate Pendants with Green Dendrite Patterns

Moss agate registers 6.5 to 7 on the Mohs hardness scale, making it durable enough for regular wear. The stone forms in volcanic rock cavities where silica-rich waters deposit layers of chalcedony over time. Iron oxides create the green and brown branching patterns, while manganese contributes darker filaments. Major deposits occur in India, Brazil, and the western United States. Despite its name, moss agate contains no organic material and no banding, which means it's technically not a true agate. Mineralogists classify it as dendritic chalcedony. The inclusions vary from sparse wisps to dense forest-like scenes depending on the concentration of minerals present during formation. Our sterling silver settings protect and display each stone's natural pattern. The metal's neutral tone lets the green dendrites stand out without color competition.
