QuartzChalcedony

Physical Properties of Roselite

Lustre:Vitreous
Diaphaneity (Transparency):Transparent, Translucent
Colour:Rose-red, pink; rose coloured in transmitted light.
Comment:Darker coloured crystals frequently exhibit marked colour zoning due to variations in composition.
Hardness (Mohs):3½
Cleavage:Perfect
On {010}, perfect (easy).
Density (measured):3.46 - 3.74 g/cm3
Density (calculated):3.65 g/cm3
Comment:Density increases with Co content

Crystallography of Roselite

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 = 5.801Å, b = 12.898Å, c = 5.617Å
β = 107.42°
Ratio:a:b:c = 0.45 : 1 : 0.435
Unit Cell Volume:V 401.00 ų (Calculated from Unit Cell)
Z:2
Morphology:Crystals short prismatic [001]; thick tabular {001} uncommon. Terminations commonly simple and exhibiting monoclinic or orthorhombic aspect with large {122} and {122}. Druses of interlocking crystals and spherical aggregates.
Twinning:On {100}, very common, with {100} as the composition plane; also as fourlings.

Optical Data of Roselite

Type:Biaxial (-)
RI values: nα = 1.725 nβ = 1.728 nγ = 1.735
2V:Calculated: 68°
Maximum Birefringence:δ = 0.010

Chart shows birefringence interference colour range (at 30µm thickness) and does not take into account mineral colouration.
Surface Relief:High
Dispersion:r > v weak
Pleochroism:Visible
Comments:Light rose coloured material:
X = ^c~ 0° to 4° = Light rose
Y = b = Lighter rose
Z = ^c~ 90° to +91° = lightest rose

Dark rose coloured material:
X = b = Dark rose
Y = ^c +12° to +20° = light rose
Z = ^c -78° to -70° = lighter rose
