Physical properties

Formation & geological history

Formed in hydrothermal veins or cavities (geodes) where silica-rich minerals crystallize from cooling fluids. This specific 'Super Seven' variety is unique to the Espirito Santo region of Brazil, where amethyst grows alongside cacoxenite, goethite, lepidocrocite, rutile, smoky quartz, and clear quartz.

Uses & applications

Primarily used in jewelry, metaphysical practices, and as a mineral specimen for collectors.

Geological facts

This specimen is often marketed as 'Super Seven' or 'Melody Stone' because it is claimed to contain seven different minerals, even if all aren't visible in every piece. It exhibits distinct growth triangles on its faces, known as record keepers by collectors.

Field identification & locations

Identify by its purple hue and hexagonal prism shape. In the field, look for quartz crystals with phantom layers or inclusions. Collectors value these for their complex internal growth patterns and associations with other rare minerals.
