large agate slice, gilded, in a rotating stand from Brazil

A large agate slice from Brazil, gilded along the cut edge, mounted in a free-rotating stand with fully legible banding from both sides.

Agate is a banded chalcedony variety (microcrystalline quartz aggregates) with characteristic concentric banding. The banding lines document different solution phases during geode filling with varying trace element concentrations.

The gilding of the cut edge is a curatorial staging decision applied to the raw material. It contrasts the warm gold-yellow against the natural agate banding and defines the slice as a designed collector's item.

The rotating stand allows for 360° presentation; both cut surfaces are visible. Brazilian agates from Rio Grande do Sul provide the highest quality material in this slice size.

The gilding technique is an embellishment method traditionally practiced in Idar-Oberstein, which has reached the Brazilian workshop tradition of Rio Grande do Sul. It combines the natural mineral with a controlled metallic edge.

A gilded agate slice of this size is a curatorial statement. The rotating stand mounting makes the piece a dynamic collector's object that can be appreciated anew from every direction. The warm gold edge harmonizes with the grey-brown agate banding lines and gives the piece an additional visual resonance.
