Fluorite cubes (fluorescent blue) and powdery cerussite (fluorescent yellow) from the Blanchard Mine, Bingham, NM, USA.
The overall size is about 12 x 10 x 7 cm.
Biggest fluorite cubes are between 8 and 10 mm in size. In the matrix there are some small shiny galena cubes, only partially visible. Best fluorescence under long wave UV light.
The fluorescence spectra are typical for fluorite (activated by europium ions) and cerussite.
