This 1397g agate geode from Brazil features a deep amethyst crystal interior framed by natural agate banding. The sculptural cut reveals a sparkling purple quartz-lined cavity formed over millions of years within volcanic rock.
A natural calcite formation is visible within the crystal interior, adding contrast and geological character to the piece.
Weighing 1397g, this substantial geode creates a strong visual focal point for shelves, consoles or curated interior spaces.
The inner cavity is lined with densely formed amethyst crystals in soft lilac to deeper purple tones. Amethyst is a purple variety of quartz formed through trace mineral presence and natural geological processes.
A naturally occurring calcite formation has developed within the amethyst cavity, a common secondary mineral growth found in Brazilian geodes.
Brazil is known for producing high-quality agate and amethyst geodes. The visible banding and crystal structure reflect this characteristic geological origin.
