Description: A truly world-class cabinet specimen from Las Trancas, Mexico. This massive 594g geode features a botryoidal Hyalite Opal interior. However, under UV light, it reveals a rare bi-color "Christmas" reaction: the Hyalite erupts in an intense neon green, while the associated Calcite crystals across the geode glow a vibrant, contrasting red. Large, dual-reactive specimens of this caliber are rarely seen on the market and serve as a definitive centerpiece for any elite collection.
