CryoliteWikipedia
Cryolite occurs as glassy colorless white-reddish to gray-black prismatic monoclinic crystals. It has a Mohs hardness of 2.5 to 3 and a specific gravity of about 2.95 to 3.0. It is translucent to transparent with a very low refractive index of about 1.34 which is very close to that of water thus if immersed in water cryolite becomes essentially invisible.
