This is blue barite with calcite, from Sidi Lahcen, in Nador Province, Morocco. By daylight, fine lines run the length of each blade and the light lies on them like satin, the blue closer to frost than to sky. Under ultraviolet light, the specimen answers with a glow of its own, a second life that waits in the dark for the one light that can find it.
The blades never settled into a tidy crest. They crossed and leaned and built over one another, and the calcite found its room in the hollows between them. So the piece reads differently from every side: a thicket of ice at the front, a caramel shoulder at the flank, a glittering crust across the back.
In crystal traditions, blue barite has long been said to calm and clarify, and to open the way to vivid dreaming. Keep it for the late hours: put out the room lights, switch on the ultraviolet, and watch it wake.
