  • This is a very cool specimen! The major feature on this one is the well formed, albite-shrouded hackmanite crystal on the left. It is nicely fluorescent despite the albite coating. In addition, though, there are several very sharp, twinned, colourless-white crystals of eudidymite on the right side of the specimen. Very nice!
