ELBAITE IN QUARTZ
Complete, well-terminated crystals of blue-green cap elbaite tourmaline hosted within a well-sized reverse scepter quartz crystal. White albite is also present in parts of the specimen. The main quartz crystal has strong translucency in areas that allow one to see the embedding of the tourmaline straight through it. It's rehealed in many places, with complex growth all around, and the reverse scepter termination is pristine. Alluring and unique piece from a world renowned locality.

Elbaite-quartz assemblages occurs within alpine-type fissures at Stak Nala, formed through hydrothermal processes under conditions of regional metamorphism. The mineralization sequence produced exceptional specimens featuring elbaite crystals intergrown with clear quartz, indicating complex fluid evolution during crystallization. These minerals precipitated in open spaces within the host gneiss under moderate to high-pressure conditions during the Himalayan orogeny.
