Fig. 1

The single-crystal diffraction patterns (a) and (b) were collected during compression at 10 and 25 GPa. Circular Debye rings correspond to the polycrystalline gold standard used as a pressure calibrant. (c) represents a sketch of the peaks of quartz (gray) and the high-pressure phase (colored) at 26 GPa (cf. (b)). The red, orange, and blue reflections refer to different orientations of the same high-pressure phase within the quartz single crystal (cf. Figure 5).
