Great agate tower with unusual banding

An Agate Tower from Brazil and Botswana in a slender column geometry. The grain shows an unusual swirling variant, not classic parallel banding.

The unusual grain documents more complex flow patterns during geode filling. Wavy or swirling lines document changing solution movements in the cavity.

Botswana agate provides the raw material, and Brazilian workshops process it into the tower shape. The narrow base with pronounced height results in a slender vertical presentation.

The material quality is classified by cut-polish and banding visibility. Swirling-grain pieces are a collector's item beyond standard banding.
