Natural Dendritic Agate 113.9ct 59mm Oval Cabochon

A large, generously proportioned oval cabochon in milky white chalcedony, with a broad open center that gives the stone a calm, spacious quality. The dendrites, natural manganese oxide formations, are clustered primarily around the outer edges and along the left side, forming fern-like and snowflake-like patterns in dense black against the white ground. A soft pale blue-grey chalcedony tone washes through the lower-center portion, adding quiet depth. The right side remains largely open and clean, making the dendritic border feel deliberately composed, like ink brushwork on white paper.

Brazil is one of the most consistent sources of dendritic agate worldwide, producing chalcedony with well-developed black manganese oxide inclusions in a range of forms from fine dots to elaborate branching systems. Dendritic agate is natural and untreated. At 59mm in length, this is a statement cab suited to large bezel or wire-wrap settings, or displayed as a collector piece.
