Selenite is easily one of the most underrated forms of gypsum—there’s something genuinely captivating about those clear, windowpane-like sheets, especially when you contrast them with the fibrous satin spar that usually gets all the attention.
A few things that always stand out when discussing true selenite:
Cleavage Precision: The way it splits into perfectly flat, mirror-smooth sheets along the basal cleavage plane makes it feel more like crafted glass than a naturally occurring mineral.
Optical Clarity: Historically used as windowpanes before glass production took over, high-clarity selenite has a unique way of bending and transmitting light without modern distortion.
Giant Crystal Cave Phenomena: Sites like Naica, Mexico, show what happens when hydrothermal fluids and stability meet—yielding massive selenite beams that feel completely alien…
