Botswana Agates

Botswana Agate is a variety of banded Chalcedony, a mineral of the Quartz family. It is predominantly banded in shades of pink and purplish-gray, though some layers may contain a muted brown or apricot. The volcanic activity that produced these banded stones dates back nearly 187 million years ago, and though the igneous stones of Botswana began as volcanic flow, they did not originate from normal, mountainous volcanoes. Rather the lava flowed in waves from long faults along the lower rock layers and rolled across the landscape, depositing layer upon layer of Silica/Quartz, creating the extra fine banding and patterns which make Botswana Agates highly unique and desirable.
