These two pieces of moss agate AKA tree agate tumblestones came from an old crystal collection. They feature a bright white chalcedony or quartz with a pattern of green mossy parts in it. We call the mossy parts dendrites. So this is technically dendritic agate, which is a scientifically recognised agate pattern.

These two tumblestones were donated ot team TSC in April of 2026. They are seeking their new homes. They have been washed in hot, soapy water and are ready to go.
