The in-situ angle dispersive X-ray powder diffraction of natural pyrope collected from Zhenyuan in China using synchrotron radiation has been measured under high pressure (0~25.3 GPa) conditions with diamond anvil cell (DAC). We have not found any convincing evidence for a phase transformation in the experimental pressure range. The XRD patterns were then refined by using the refinement module combined in the Materials Studio program. We fit the Birch-Murnaghan equation of state and obtained its ambient pressure bulk modulus B0=199 GPa (B′0=4).
