Physical Properties of Beryllonite

Lustre:Sub-Vitreous, Resinous, Waxy, Greasy
Diaphaneity (Transparency):Transparent, Translucent
Comment:Pearly at times on {010}.
Colour:Colourless, white, rarely pale light yellow; colourless in transmitted light.
Streak:White
Hardness (Mohs):5½ - 6
Tenacity:Brittle
Cleavage:Perfect
On {010} perfect; on {100} good but interrupted; on {101} poor; on {001}, in traces.

Crystallography of Beryllonite

Crystal System:Monoclinic
Class (H-M):2/m - Prismatic
Space Group:P21/b {P1 1 21/b} {P21/c} {P1 21/c 1} {P21/a}
Space Group Setting:P21/c
Cell Parameters:a = 8.178(3) Å, b = 7.818(3) Å, c = 14.114(6) Å
β = 90°
Ratio:a:b:c = 1.046 : 1 : 1.805
Unit Cell Volume:V 902.39 ų (Calculated from Unit Cell)
Z:12
Morphology:Crystals tabular {010} to short prismatic [010]. Crystals are frequently very complex, especially in the zones [100] and [010]. Faces in the zone [010] near {100} may be united in oscillatory combination. Crystal faces often dull or roughened, or, in some cases, delicately etched. Crystals frequently exhibit a columnar structure due to the presence of hollow canals and fluid cavities arranged parallel to [010].
Twinning:On plane {101}, as both contact and penetration twins; repeated at times, or in pseudo-hexagonal stellate forms; also polysynthetic {110} and {100}.
Comment:Marked orthorhombic pseudo-symmetry.
