Repeated sedimentation, made visible as stripes. Each band is a mineral layer deposited in a different era. To look at its cross-section is to read a geological column.
Jasper is found worldwide, yet specimens with clearly defined banding come only from specific strata in South Africa, India, Russia, and Australia. Shifting concentrations of iron and impurities across ages produce the colour variations naturally.
A pattern made without intention. Repetitive, yet never once the same.
