Identification Molecular Weight 12.01 u Color Typically yellow, brown or gray to colorless. Less often in blue, green, black, translucent white, pink, violet, orange, purple and red.[1] Crystal habit Octahedral Crystal system Isometric-Hexoctahedral (Cubic) Cleavage 111 (perfect in four directions) Fracture Conchoidal - step like Mohs Scale hardness 10[1] Luster Adamantine[1] Polish luster Adamantine[1] Refractive index 2.4175–2.4178 Optical Properties Singly Refractive[1] Birefringence none[1] Dispersion .044[1] Pleochroism none[1] Ultraviolet fluorescence colorless to yellowish stones - inert to strong in long wave, and typically blue. Weaker in short wave.[1] Absorption spectra In pale yellow stones a 415.5 nm line is typical. Irradiated and annealed diamonds often show a line around 594 nm when cooled to low temperatures.[1] Streak White Specific gravity 3.52 (+/- .01)[1] Density 3.5-3.53 g/cm³ Diaphaneity Transparent to subtransparent to translucent
