Exceptional pair of amethyst geodes with great color and a beautiful wide rim

A pair of amethyst geodes from Brazil with an unusually wide agate rim and uniformly deep violet coloring of the crystal field.

The wide whitish agate rim documents an extended chalcedony phase before the actual amethyst growth. Such pieces are rarer on the market than the usual narrow-rim geodes, because the mineralization occurred in two clearly separate main phases.

Amethyst belongs to the quartz family and crystallizes in the volcanic gas cavities of lava flows. The violet color is caused by tiny traces of iron in the crystal lattice, which are stimulated into color centers under natural radiation.

The elongated, upright shape of both halves allows for an unusual display option: two pillar-like pieces facing each other, together forming an entrance frame.

The uniform distribution of crystals over the entire height indicates slow, undisturbed crystallization in a uniformly flushed cavity.

A collector's item of the highest class, suitable as a central anchor composition in a spacious living room.
