very beautiful citrine geode with great shape

A very beautiful citrine geode from Brazil, with an unusually harmonious shape. Its 123 cm height makes it a stele-like collector's item with visual elegance.

Citrine forms in volcanic geodes of the Serra Geral Basalt Formation from silica-rich solutions. The honey-yellow color comes from traces of trivalent iron. The shape of the geode follows the geometry of the original cavity; harmonious slender shapes are rarer than irregular geodes.

Brazilian citrine deposits in Rio Grande do Sul yield particularly intensely colored material. Slender tall geodes are classified as tower geodes in the collector's trade and are particularly sought after for foyer or gallery displays.

Recovering intact slender geodes from the basalt layers requires special caution from miners, as they are very brittle.

A collector's item with a harmonious shape and collector-relevant height.
