Red Botswana Agate 10mm Round - 15-16 Inch 02172022FEATURE calcium carbonate and other materialsRed Botswana Agate displays highly defined parallel banding, usually in white on hues of brown, gray, pink, tan, apricot and purplish red.

This lava rolled across the landscape, depositing layer upon layer of Quartz silicate to create the banding and patterns now prized in Botswana Agate.
