Pink Botswana Agate 12mm Round Beads 16 inch Strand

Sweet Mix of Earthy Pink Colors Pink Botswana Agate 12mm Beads, 16 inch strand.  Botswana Agate is a variety of banded Chalcedony, a mineral of the Quartz family. It is predominantly banded in shades of pink and gray, though some layers may contain a muted brown or apricot. These stones were produced by volcanic activity nearly 187 million years. The banding in these stones were produced when lava flowed in waves from long faults along the lower rock layers and rolled across the landscape, depositing layer after layer of silica quartz thus creating the extra fine bands known to Botswana agates.
