Amethyst Stalactite
Also known as: Amethyst flower, Amethyst star slice
Variety of Amethyst.
📜 Key facts
| Age | Lower Cretaceous basalts, about 135–130 million years old |
|---|---|
| Origin & sources | Artigas, Uruguay, and Rio Grande do Sul, Brazil, from inside large amethyst geodes in basalt. |
| Composition | Amethyst (quartz) grown around a core of chalcedony or agate, usually sold as polished slices |
How it forms
Inside gas cavities in basalt, silica-rich water dripped and built finger-like chalcedony columns, which later got coated in amethyst crystals. Cut across, each slice shows a chalcedony 'eye' surrounded by a ring of purple crystals that looks like a flower or star.
