This acanthite crystal is unusually flattened on one axis, so it looks like a square perched upon a cluster of cubes, and displays very dramatically like some sort of oddly beautiful building blocks. While the finds from Guanajuato are classics, this little jewel also has unusual aesthetics compared to the average example.
