For the earth science student who's had "wait, its hardness isn't constant?" as a genuine lightbulb moment, the metamorphic rock specialist, or anyone drawn to a mineral that refuses to follow the rules.

Kyanite has a property that breaks the usual mineral rulebook, its hardness actually changes depending on which direction you scratch it, a trait called anisotropic hardness that makes it a favorite oddity in mineralogy classrooms.

The Kyanite Shirt features a hand-watercolored illustration of its signature blue blade-shaped crystals, with real metamorphic mineral data, hardness range, formula, crystal system printed alongside.
