Stacked, colorless halite cubes to about 1 cm with a few colorless, transparent selenite gypsum blades, these to about 1.5 cm in length. The halite displays intense orange fluorescence under shortwave UV. The matrix is thin and concave, hollow on the underside of the specimen. Sits perfectly for display and in superb condition. Halite has a reputation for instability (most likely due to impurities); I have owned this sample since 2010 and it shows no signs of decay.
