Botswana Agate is a variety of banded Chalcedony, a mineral of the Quartz family. It is predominantly banded in shades of pink and grey, though some layers may contain a muted brown or apricot. Agate has a lower intensity and vibrates to a slower frequency than other stones, but is highly regarded as a stabilizing and strengthening influence. [Simmons, 6] It is excellent for balancing emotional, physical and intellectual energy, and in harmonizing yin and yang, the positive and negative forces of the universe. (Hall, 39)
