Diaphaneity of diamond
WebLustre depends upon a mineral’s refractive power, diaphaneity (degree of transparency), and structure. Variations in these properties produce different kinds of lustre, whereas variations in the quantity of reflected light produce different intensities of the same lustre. http://webmineral.com/data/Diamond.shtml?MobileOptOut=1
