dreamy lilac amethyst geode pair from Brazil

An amethyst geode pair from Brazil in a light lilac hue. The light pastel variant of amethyst is rarer than the intensely violet pieces and forms with reduced iron concentration in the crystallizing cavity.

Amethyst is the violet quartz variety, colored by iron trace elements and natural radiation exposure. The lilac hue indicates a lower iron concentration or a shorter radiation exposure time. The result: the same mineralogy, a different color.

Brazilian geodes from the basalt flows of Rio Grande do Sul provide a wider spectrum of amethyst shades than Uruguayan material, from light lilac to deep violet. Pastel pieces like this are sought after in the collector's market as a complementary variant to the standard coloring.

Geode pairs form when the geode is split along its axis of symmetry during recovery. Both halves then mirror the same growth geometry of the inner wall.

A collector's item with a lighter color variant than usual, suitable as a visual contrast next to darker amethysts in a collection.
