Polyhedral agate - Sitio Garguelo, Paraiba, Brazil

€15.00

Tax included

A polished polyhedral agate with a particularly well-defined triangular shape, its edges slightly rounded by polishing.

The piece features a beautiful sequence of concentric zones in shades of gray, beige, and white, with a wide translucent border and a striking white band that highlights the agate’s geometric shape. In the center, a small cavity is lined with fine, sparkling crystals, adding depth and brilliance to the piece.

The agate’s partial transparency also allows you to appreciate the different growth layers and a few small brownish inclusions, which give the piece its natural character.

3.2 × 1.8 × 1.1 cm

Highlights of this piece:

- A particularly well-defined triangular/polyhedral shape
- Smooth, lustrous edges thanks to the polishing
- Beautiful concentric zoning in white, gray, and beige
- A small central cavity lined with sparkling microcrystals
- Translucent borders
- A unique, graphic, and decorative specimen, suitable for display in a collection or set as a pendant

For your information

Paraíba polyhedral agates are agates that formed within polygonal cavities, giving the specimens their characteristic geometric contours. They were discovered in Brazil in the 1970s. Their formation is generally interpreted as the total or partial filling of spaces left between ancient crystals, often attributed to calcite (see *Le Règne Minéral* No. 163)
