Large Amethyst & Banded Agate Cathedral Geode with Calcite Inclusion - Height: 30 cm - Width: 15 cm- 4.5 kg

An exceptional, upright amethyst cathedral geode specimen characterized by a thick, beautifully polished border of blue-grey and white banded agate.

The deep central cavity is lined with glittering, pale-lavender to white amethyst points and features a striking, naturally grown golden-yellow calcite inclusion nestled near the base.

This remarkable mineral specimen offers a captivating window into a prehistoric volcanic pocket. The exterior features a wide, smoothly polished rim showcasing flawless, concentric agate banding in rich tones of smoky blue-grey, icy white, and soft cream. This structural framing creates a stark, elegant contrast against the highly textured, crystalline interior cavern.

Inside the deep, protective hollow, a dense field of sparkling microcrystalline quartz and light lavender amethyst druzy blankets the walls. The standout feature of this specific lot is a distinct, naturally nested cluster of golden-yellow calcite located within the crystal bed. This contrasting mineral formation breaks the symmetry of the geode beautifully, elevating its value as a true collector's conversation piece.

The geode has been meticulously cut with a completely flat, stable base, allowing it to stand unsupported as a majestic centerpiece for high-end home decor, mineral collections, or wellness spaces.
