Pink Manganocalcite from Bulgaria in UV Cage

These Manganocalcite crystals come from Bulgaria. They are white, very slightly pink. But presented in a black brass and metal cage that we have created, they completely transform before our eyes thanks to a fascinating property: its intense fluorescence under UV light. This group of crystals will take an intense pink color when you turn on the Ultra Violet lamp discreetly hidden in the upper part of this presentation cage. This is due to the presence of manganese, and it is typical of specimens from the Zlatograd mine. This piece allows to clearly observe this scientific phenomenon, while keeping in mind refinement and precious aesthetic.
