Kristallsystem-Referenzkarte

I keep this chart on my desk while sorting my collection, and being able to compare all six crystal systems side by side has made identifying my specimens way easier. It's laminated too, so I don't worry about smudging it with dusty hands.

The layout is so clear that I can instantly tell the difference between tetragonal and orthorhombic — no more flipping through books. Makes my crystal study sessions much more efficient.
