    Amethyst druses are crystalline formations belonging to the quartz group, with the chemical formula SiO2. They are characterised by their distinctive violet colour, resulting from the presence of iron and exposure to natural radiation during their formation.

    These impressive structures originate from cavities in volcanic and sedimentary rocks, where amethyst crystals grow on the inner surface, creating spectacular mineral landscapes. Highly valued in collecting, amethyst druses stand out for their brilliance, depth of colour and the beauty of their crystals, making them essential pieces for any mineral collection.
