• Schäferite - Wikipedia

    en.wikipedia.org/wiki/Schaferite Schäferite is a rare vanadate mineral with chemical formula Ca 2 NaMg 2 [VO 4] 3.Schäferite is isometric, which means that it has three axes of equal length and 90° angles between the axes. Schäferite is isotropic, meaning that the velocity of light is the same no matter which direction the light passes through.
