A flat cleavage plate of colorless, very clear gypsum. (The find consisted of large uninteresting gypsum masses, so these were cleaved to better show the internal structure.) Although the term selenite is **widely** misused, this gypsum example is quite clear and transparent, and hence worthy of the moniker. At the center is a hazy inclusion stripe, consisting of at least unidentified minerals: an amorphous muddy brown (limonite?), a black, somewhat iridescent, octahedral (?) species (cuprite?), and a white, nonfluorescent, crystalline mineral. This stripe is also the nexus point of twinning; angled growth lines radiate away from this central point. Reminiscent of the central line in faden quartz. Interesting under the microscope. A must for the collector of twins, of gypsum or of Greek minerals. From finds in 2016 or 2017.
