The elastic behaviour and the high-pressure structural evolution of a natural topaz, Al2.00Si1.05O4.00(OH0.26F1.75), have been investigated by means of in situ single-crystal X-ray diffraction up to 10.55(5) GPa. No phase transition has been observed within the pressure range investigated. Unit-cell volume data were fitted with a third-order Birch-Murnaghan Equation of State (III-BM-EoS). The III-BM-EoS parameters, simultaneously refined using the data weighted by the uncertainties in P and V, are: V (0)=345.57(7) angstrom(3), K (T0)=164(2) GPa and K'=2.9(4). The axial-EoS parameters are: a (0)=4.6634(3) angstrom, K (T0)(a)=152(2) GPa, K'(a)=2.8(4) for the a-axis; b (0)=8.8349(5) angstrom, K (T0)(b)=224(3) GPa, K'(b)=2.6(6) for the b-axis; ...
