Geological Origin and Formation
Amethyst is a variety of quartz (SiO₂), formed within volcanic basalt cavities where silica-rich fluids crystallised over millions of years. In southern Brazil, particularly the Minas Gerais and Rio Grande do Sul regions, these conditions have produced some of the world’s finest Amethyst geodes. The egg shape of this specimen has been expertly cut and polished to enhance the natural geode interior, which showcases densely packed clusters of purple Amethyst points.
Brazilian Amethyst geodes often form in large hollow nodules, with crystals growing inward from the outer basalt wall. Over time, iron impurities and natural radiation produced the distinctive purple colouration that makes Amethyst so prized. Associated minerals frequently found in these deposits include Agate, Chalcedony, and occasional Calcite, which may appear as secondary formations within or near the cavity.
Mineralogical Characteristics
Amethyst is part of the trigonal crystal system, forming six-sided prismatic crystals with pyramidal terminations. The crystals inside this geode display rich violet hues ranging from deep royal purple to lighter lilac tones, a result of trace iron ions interacting with natural geological processes. The interior surfaces shimmer with transparency and semi-transparency, allowing light to pass through the crystal tips and creating a remarkable visual depth.
With a Mohs hardness of 7, Amethyst is a durable mineral, resistant to everyday wear while maintaining its lustrous finish. This specimen is entirely natural, with no artificial treatments or enhancements. Its large size, clarity, and even distribution of colour highlight the superior quality that defines A-grade Amethyst.
Size, Shape, and Presentation
Weighing 22.45kg, this Amethyst Egg Geode is a substantial and highly decorative mineral specimen.
