Amethyst geode is a violet-coloured variety of quartz

Amethyst geode is a violet-coloured variety of quartz, with some samples formed over hundreds of millions of years. Amethyst geode crystals are typically composed of quartz or chalcedonic deposits, but other minerals are commonly found within geodes.

Amethyst geode is a violet-coloured variety of quartz, with some samples formed over hundreds of millions of years. Amethyst geode crystals are typically composed of quartz or chalcedonic deposits, but other minerals are commonly found within geodes.

The formation of geodes begins from a small piece of limestone or anhydrite and over time, mineral-rich waters seep into the burrow allowing minerals to harden around the small rock. It is the repetitive layering of hardening deposits from mineral-rich waters that eventually forms the crystalline structure and outer crust of the geode.

Amethyst geodes are commonly collected for display at home. Some cultures believe geodes have the ability to attract wealth and luck, to bring good fortune and block evil spirits. Amethyst geode can also be used as a magnetic filter.

Origins: Brazil, Uruguay and other South American countries.

 

Exhibit Introduction: Amethyst geodes typically have three layers, with a crystalline inner structure and an outer protective crust. However, this exhibit showcases an exceptional geode, where the crystal grains have grown and formed clusters in the shape of stalactites, which may also resemble chandeliers but can be interpreted as meteor showers.
