Amethyst Slice

An amethyst geode section from Brazil with clear, rich purple crystals and a wide rock crystal border. The section shows the natural crystal arrangement of an opened geode.

Amethyst sections form in volcanic cavities when inwardly growing SiO₂ solutions leave behind well-formed crystals. The combined layer of rock crystal and amethyst documents changing geochemical conditions during growth.

The generous display surface and clear crystal zoning make this section a display cabinet piece with clear mineralogical readability. A compact gallery presence with precise crystal formation.
