Nathan C. Martin photograph and specimen. I collected this small (~3mm) spray of colorless milarite crystals in 2002 from one of the many boulders at the then deserted construction site. These colorless hexagonal prisms always intrigued me because they fluoresce a sky blue color under mid-wave UV light. Jim Nizamoff recently confirmed my suspicion that these were milarite crystals by performing an SEM-EDS analysis. To my knowledge these are the only identified milarite crystals from Connecticut.

Jim Nizamoff EDS analysis of Nathan C. Martin milarite specimen. This is the SEM-EDS analysis spectrum from Jim Nizamoff that confirms that my Trumbull, CT crystal spray is milarite. Although the analysis technique cannot identify the Be, the identification is based on the fact that the K, Ca and Al are close to the correct ratio in comparison with Si.
