Moss Agate gets its color from greenish, moss—like inclusions that come from a mineral called chlorite. Sometimes there will be so many inclusions that the beads will look almost black — but when you hold it up to the light, you will see the inclusions. Moss Agate can also be almost clear — or have white or light green inclusions.
10mm Moss Agate Gemstone Round beads are sold on 16" (40cm) strands.
