Each stone varies. Named for the area in Africa where it is mined, Botswana Agate is called the Sunset Stone because it retains sunlight and comforts people through the night. It's often used to help balance physical, mental and intellectual energies and harmonizing yin and yang. Botswana Agate is excellent for those serious about giving up smoking. To increase success drink an elixir first thing each morning, made by soaking the crystal in water for a few hours. This stone helps with sensitive children or teens when it comes to bullying and it promotes inner stability with warm energy. 
Botswana agate is a great stone to use if someone wants to rid their body of toxins or treat depression as it is an overall good healing stone.
