Botswana Agate 7x8mm Faceted Swirl Oval - 15-16 Inch HPS06302022 from pastel to bright toBotswana Agate displays highly defined parallel banding, usually in white on hues of brown, gray, pink, tan, apricot and purplish red. Botswana Agate was formed nearly 187 million years ago by lava flowing in waves from long faults in the earth. This lava rolled across the landscape, depositing layer upon layer of Quartz silicate to create the banding and patterns now prized in Botswana Agate.
