Great Citrine Geode Pair with Crystal Hedgehog

A Citrine Geode Pair from Brazil in a deep amber-gold hue, featuring the hedgehog-like growth pattern known for its dense crystal distribution across the entire inner surface.

Citrine belongs to the quartz family. The warm golden-yellow color results from iron trace elements in the crystal lattice under natural irradiation over millennia.

The crystal hedgehog formation occurs when the geode develops hundreds of fine, densely packed crystal points instead of a few large ones. This requires particularly uniform mineralization conditions and a finely pulsating silicic acid concentration.

Both halves show the dense crystal distribution from base to top edge. The narrow whitish agate rim forms the geode wall between the volcanic matrix and the crystal interior.

Brazilian citrine geodes from Rio Grande do Sul are formed in volcanic gas cavities.

A collector's item with a warm presence and unusual crystal density, suitable as a facing pair in a living space.
