Description:
One of the best four-colors fluorescent combination from the Dara-i-Pioz Massif in Tajikistan. Baratovite needles on a matrix of agrellite and albite/microcline, and some unidentified uranyl minerals. Under shortwave UV light the baratovite fluoresces bright light blue, the agrellite pink (best in midwave), the albite/microcline dull red, and the uranyl minerals the typical green. It is quite rare to find such pieces.
