Top Quality - Amethyst - 30x30x16 cm - 'Double Pyramid' Geode- 16.5 kg

Amethyst is a renowned variety of quartz distinguished by its regal purple color, which can range from a soft lilac to deep violet hues. This exceptional 'Double Pyramid' geode features amethyst crystals arranged in two opposing pyramid-like formations within a 30 x 30 x 16 cm specimen weighing 16.5 kg. Geodes are hollow rocks lined with crystals formed when mineral-rich water seeps into cavities and slowly deposits crystals over millennia. Amethyst's purple coloration results from trace amounts of iron and natural irradiation within the quartz structure. Historically prized for its beauty and believed protective qualities, amethyst has been used for ornamental and jewelry purposes since ancient times. Large geodes like this double pyramid specimen are especially valued for display, providing striking insights into natural crystal formation and the geological history of the area where they originated.
