Amethyst druses.
Size: approx. 7-17 cm.
SET OF 12 UNITS
Amethyst druses are crystalline formations belonging to the quartz group, with the chemical formula SiO2. They are characterised by their distinctive violet colour, which is the result of the presence of iron and exposure to natural radiation during their formation.
These impressive structures originate in cavities in volcanic and sedimentary rocks, where amethyst crystals grow on the inner surface, creating spectacular mineral landscapes. Highly prized by collectors, amethyst druses stand out for their brilliance, depth of colour and the beauty of their crystals, making them essential pieces for any mineral collection.
