Madeira Orange Citrine Portal Slice with Crisp White Agate FrameCitrine Geode Portal Slice with Imponent, Sculptural Formation This rare, large citrine geode portal slice stands out for its natural sculptural formation and the way the golden orange druzy wraps around the entire opening. The crystals bring beautiful luster, with a clean, gemmy look and bright reflections, creating a warm glow that displays beautifully in a collection, meditation space, or dcor. What really makes this piece special is the formation.
