A cluster of water-clear gypsum crystals showing a magnificent luster and transparency. We would like to emphasize the “phantoms” inside some crystals, with inclusions and a deepest yellow tone. These “phantoms” are not very common. On a white alabaster matrix covered by small gypsum crystals. Under short and long wave ultraviolet light sources all specimens show fluorescence and evident phosphorescence. Fluorescence UVC & UVA. THE MAIN CRYSTAL IS: 2,5 x 0,9 x 0,2 cm.
