Amethyst & Agate - 101x23x18 cm - Matched Pair - Cathedral Geode- 80.9 kg

Amethyst and agate cathedral geode pairs are large, naturally occurring formations where an amethyst crystal interior is encased within a chalcedony agate shell. These matched pairs represent split geodes, often carefully cut to reveal symmetrical, mirror-like surfaces showcasing deep purple amethyst crystals surrounded by patterned agate bands. Such large specimens are prized for their dramatic display and are often used as striking decorative pieces or in spiritual and meditation settings. The geological processes forming these geodes involve volcanic activity and subsequent mineral deposition in cavities, creating layers of silica that form both agate and amethyst over time.
