This is an antique specimen that appears to have been labeled before the first mention of  Andersonite in 1948. The vivid blue fluorescence of the Andersonite overshadows the pale yellow-green Bayleyite fluorescence. The differences in the fluorescence between Bayleyite and Andersonite can be observed in the main picture.

This specimen was stabilized with Paraloid B-72,  a commonly used conservation material in the field of mineral preservation, providing excellent protective qualities for stabilization and long-term conservation. The stabilization process results in a specimen that won’t disintegrate over time like these minerals are notorious for.
