Beautiful Agate Tower

An agate tower from Brazil/Botswana. A particularly slender vertical column geometry with continuous banding stratigraphy over the full height.

Agate is a banded chalcedony variety with characteristic concentric banding. The banding lines document changing solution phases during geode filling. Botswana agate shows typical gray-brown banding with occasional blue-gray accents as its own deposit signature.

The tower cut shape with a narrow cross-section and pronounced height is a striking vertical column geometry. In this narrow shape, the banding acts as continuous stratigraphy.

Brazilian processing workshops cut and polish the Botswanan raw material into these column shapes. The premium classification evaluates banding visibility and polishing quality.
