Cavansite Crystal Sprays in Natural Vug on Matrix, Blue Mineral Specimen, Approx

Natural Cavansite Crystal Sprays in Matrix A striking collector's mineral specimen featuring vivid blue cavansite crystal sprays nestled deep within a natural vug in the contrasting matrix. At first glance the specimen has an earthy, understated appearance, but look inside the cavity and an intense blue pocket of delicate radiating cavansite crystals is revealed. The recessed position of the crystals creates an unusual hidden-crystal display and has helped protect the delicate formations. The surrounding matrix also displays areas of fluorescence under UV light, including a particularly bright fluorescent crystal or cluster. UV photographs are included to show the observed reaction; the fluorescent mineral has not been independently identified. Specimen details - Mineral: Cavansite on matrix - Approx. size: 7.5 cm - Natural crystal-lined vug/cavity - Multiple vivid blue radiating crystal sprays - UV-reactive areas within the surrounding matrix - Flat/sawn area to the reverse/base You will receive the exact specimen photographed This is a natural mineral specimen, so irregular surfaces, inclusions, fractures and variations are part of its geological formation rather than manufacturing defects. Please note: Colours can vary slightly according to lighting, screen settings and viewing conditions. UV photographs demonstrate the specimen under UV illumination and should not be taken as identification of the fluorescent associated mineral.
